We examined the influence of SSD pace on gaming efficiency in 11 titles — we analyzed from SATA to PCIe 5.0 to see whether or not upgrading to a sooner NVMe SSD would have an effect

We examined gaming efficiency with each NVMe and SATA SSDs throughout 11 video games to find out if upgrading to a sooner drive is value it. Solid-state drives (SSDs) have been a staple of PC gaming for years, however their significance grew considerably with the launch of the PlayStation 5 and Xbox Series X|S in 2020. Both consoles characteristic high-speed NVMe SSDs and storage architectures designed to totally leverage their capabilities, enabling sooner asset streaming and lowering conventional storage bottlenecks.

As a end result, sport builders have more and more developed their titles for SSDs, with many trendy video games now itemizing them at least system requirement. But how precisely do video games use SSDs throughout gameplay, and does upgrading to a sooner SSD really enhance gaming efficiency? In this text, we’ll look at SSD exercise in trendy video games and decide whether or not increased storage speeds translate into a greater gaming expertise. Given the surge in SSD costs, will a slower drive ship comparable gaming efficiency to high-end options?

Load Times

Load Times

While this text focuses totally on SSD exercise and efficiency throughout gameplay, loading instances stay some of the vital benefits of solid-state storage. It’s well-known that video games can take a number of minutes to load from an HDD, whereas trendy SSDs usually cut back load instances to only a few seconds.

The hole between SSDs is far smaller. In some titles, PCIe NVMe drives can load video games a number of instances sooner than SATA SSDs, however in lots of circumstances, the distinction is comparatively small. Naturally, totally different generations of PCIe SSDs have even smaller variations, with flagship drives usually delivering solely marginal enhancements to loading instances regardless of their considerably increased sequential throughput.

Disk I/O Operations in Games

Disk I/O Operations in Games

Before inspecting the efficiency outcomes, it is necessary to grasp the sorts of disk I/O operations that video games usually generate. Two key metrics are block measurement and queue depth. The block measurement of an I/O operation defines the dimensions of the chunk of information a sport will learn at one time, whereas queue depth is the variety of pending I/O requests {that a} storage gadget has queued at anybody time.

During gameplay, the overwhelming majority of storage exercise consists of random learn operations as sport property are streamed from storage into reminiscence. Sequential reads are much less frequent, and write exercise is mostly minimal.

Microsoft provides several storage optimization recommendations for developers in its DirectStorage documentation. Although these guidelines are intended for DirectStorage-enabled titles, many of the underlying principles apply to games in general, even if they do not use DirectStorage. Among Microsoft’s recommendations are the use of block sizes of at least 32k and sufficiently high queue depths to maximize storage throughput.

Modern games typically employ 32k or 64k random I/O requests. However, despite Microsoft’s recommendations, most games continue to operate at relatively low queue depths.

Performance Comparison

Performance Comparison

Now we will examine SSD activity and compare performance across different SSD generations. The games included in our testing were selected because they either exhibited higher storage bandwidth than usual, had greater peak or average SSD utilization, had support for DirectStorage, or because they are popular titles that many gamers would be interested in seeing analyzed from a storage-performance perspective.

To place as much stress as possible on each SSD, all testing was conducted with 16GB of system memory. Using a smaller memory capacity reduces the amount of game data that can be held in RAM, forcing games to rely more heavily on the SSD than they would in a 64GB configuration. It also better reflects the configurations found in many mainstream gaming PCs. That said, we observed little difference in SSD activity when comparing 16GB and 64GB memory configurations.

When interpreting the SSD activity data below, it is important to understand that 100% utilization does not necessarily mean an SSD is reaching its maximum rated bandwidth. For example, a PCIe 4.0 SSD reporting 100% utilization is unlikely to be delivering its full 7.5 GB/s of sequential read throughput. In gaming workloads, SSDs can become fully utilized while transferring data at significantly lower bandwidths.

This is because the speeds advertised by SSD manufacturers are based on sequential read performance, whereas games primarily rely on random reads. While random-read throughput can approach sequential-read speeds under certain conditions, doing so requires sufficiently large block sizes and high queue depths. Although modern games often use relatively large block sizes, they typically do not use the high queue depths needed to fully saturate an SSD’s theoretical bandwidth.

We have also chosen not to test any traditional hard drive disks. There are many documented examples of modern games performing poorly, taking an unbearably long time to load, or having visual issues when installing the game on an HDD. There are some games where this may not be an issue, but we still do not recommend playing modern games on an HDD.

The testing was conducted in gameplay. No built-in benchmarks were used. We found that SSD activity increases with higher settings, so that is where we focused our testing. We set each game to its absolute maximum settings.

We used HWiNFO to measure SSD activity and set it to the lowest polling rate possible to capture activity accurately without incurring overhead.

Test system

Forspoken

Forspoken

Forspoken was the first game to support DirectStorage on PC. DirectStorage is a feature that aims to allow games to make full use of high-speed storage devices while reducing the CPU overhead associated with making reads from disk.

Looking at the table below, you can see that it does exhibit a fairly high peak and average bandwidth. In fact, it’s the highest average bandwidth we have seen in any game we have tested. Average utilization is also quite high, and the game hits 100% SSD utilization frequently.

How does this translate to performance?

While there is no difference in performance between the PCIe NVMe SSDs, you can see that having a PCIe SSD can give you a large boost in the 1% lows compared to a SATA SSD. We see a 39% increase in 1% lows at 4K, a 51% increase at 1440p, and a 22% increase at 1080p.

The higher peak and average bandwidth used by the PCIe drives resulted in higher 1% lows in this game, which makes for a smoother gameplay experience.

Alan Wake 2

Alan Wake 2

Alan Wake 2 makes extensive use of modern rendering technologies, including path tracing, mesh shaders, and RTX Mega Geometry. In a recent interview, Remedy defined that the sport operates with a set reminiscence finances, repeatedly streaming the property required for the present scene from the SSD whereas evicting property which might be now not wanted. This strategy retains reminiscence utilization beneath management regardless of the sport’s extremely detailed textures and geometry, making Alan Wake 2 some of the storage-intensive titles accessible at the moment.

The SSD exercise will increase with decision on this sport. We see a median of over 200 MB/s on every drive at 4K, which is uncommon for a sport. We additionally see a whopping 5.1 GB/s of peak bandwidth on a PCIe 5.0 SSD at 4K.

How does this influence efficiency?

Unlike Forspoken, we don’t see any distinction in efficiency right here for any of the drives examined.

Although the sooner SSDs attain increased peak bandwidth, these peaks are solely temporary bursts slightly than sustained transfers. In different phrases, the sport is just not repeatedly streaming a number of gigabytes of information each second. Instead, it transfers smaller quantities of information over very brief intervals, leading to excessive instantaneous bandwidth readings. As a end result, the typical bandwidth is the extra significant metric, and it stays comparatively comparable throughout all the SSDs we examined.

The common utilization on the SATA SSD can attain over 80% at 4K, however it’s not sufficient to degrade its efficiency compared to the PCIe drives.

Ratchet and Clank: Rift Apart

Ratchet and Clank: Rift Apart

The disk bandwidth via this sequence is definitely decrease than the earlier two video games. This is smart, as the sport makes use of GPU decompression, which will increase the efficient bandwidth flowing via the PCIe bus past what CPU decompression would. However, this improve in efficient bandwidth is just not mirrored within the information that’s being learn from disk.

When studying the efficiency charts beneath, it is very important word that PCIe SSDs cut back portal transition instances by roughly 2-3 seconds in comparison with SATA SSDs. On SATA drives, Ratchet subsequently spends extra time inside every portal sequence. As a end result, common efficiency and 1% lows can usually be barely increased on SATA SSDs, since there may be much less lively rendering throughout these prolonged transition intervals. However, there may be one exception.

While the SATA SSD has a bonus at 1440p and 1080p as a result of prolonged time spent inside of every portal, the 1% lows take a success at 4K. The SATA drive doesn’t deal with the primary portal transition within the sequence significantly effectively at 4K, and so the PCIe drives have a few 38% benefit in 1% lows.

This portal sequence is essentially the most storage-intensive a part of the sport. In regular gameplay, the sport makes use of considerably much less bandwidth, and so there is no such thing as a distinction in efficiency in any respect between the SATA SSD and the PCIe SSDs.

Spider-Man 2

Spider-Man 2

Spider-Man 2 was the second sport to make use of GPU decompression of property on PC. This is the third DirectStorage title we have now examined up to now.

Since the sport makes use of GPU decompression, the efficient bandwidth after decompression shall be significantly increased than what we see right here, however not one of the SSDs we examined are being careworn on this sport.

Performance is nearly equivalent on all drives on this sport.

Starfield

Starfield

Starfield is an open world sport that continually reads information from disk. It additionally regularly hits 100% disk utilization as you traverse the world.

In earlier video games, 100% SSD utilization was accompanied by a lot increased peak bandwidth. Here, the decrease peak bandwidth suggests the sport makes use of a really low queue depth for its learn operations. As you progress via the open world, it repeatedly streams information from the SSD in frequent, small transfers, retaining common bandwidth very low.

Once once more, we see no enchancment in efficiency going from the SATA SSD to any of the sooner PCIe NVME SSDs.

DOOM: The Dark Ages

DOOM: The Dark Ages

DOOM: The Dark Ages was the primary sport to listing an NVMe SSD as a requirement. Not solely is it listed as such on the PC system necessities, however Bethesda has a assist web page that reiterates that putting in the sport on an NVMe SSD is required.

The builders at idSoftware talked about that the sport makes use of a proprietary ultra-fast steady sector streaming tech that nearly eliminates load instances between ranges.

The drives we examined are hardly being careworn in DOOM: The Dark Ages.

Given the disk utilization figures, it comes as no shock that all the examined drives ship equivalent gameplay efficiency.

Although this text focuses on in-game efficiency slightly than loading instances, we additionally discovered little distinction in load instances when utilizing a SATA SSD. Loading screens weren’t noticeably longer, and we noticed no visible artifacts or streaming points whereas enjoying on the slower drive.

Based on our testing, it’s unclear why Bethesda lists an NVMe SSD as a requirement. A SATA SSD offered an indistinguishable gameplay expertise, with no measurable efficiency drawbacks or observable streaming points.

Dead Space Remake

Dead Space Remake

Dead Space Remake made headlines when it launched with abhorrent efficiency and stuttering points. But how a lot of that was resulting from streaming from slower storage? Does a sooner SSD assist efficiency?

Although common disk utilization and bandwidth are comparatively low, the sport regularly reaches 100% utilization. Yet even throughout these intervals, peak bandwidth stays effectively beneath what PCIe SSDs can obtain beneath high-queue-depth random workloads. This signifies the sport is issuing learn requests at a really low queue depth, leaving a lot of the SSD’s accessible efficiency untapped. Additionally, the distinction in common bandwidth between the SSDs is minimal.

All drives present the identical efficiency. There is nothing to be gained from a sooner SSD on this title.

Cyberpunk 2077

Cyberpunk 2077

We included Cyberpunk 2077 in our testing as a result of the sport options a big and seamless open world, and it is without doubt one of the hottest video games ever launched.

The common bandwidth is by far the bottom we have now seen within the video games examined up to now. This is just not fully shocking. Although the sport was launched in the identical yr because the PlayStation 5 and Xbox Series X|S, growth started effectively earlier than these consoles have been launched. As a cross-generation title, it additionally wanted to run on the earlier technology of consoles, which relied on mechanical laborious drives. As a end result, the sport’s streaming system was designed to carry out effectively on considerably slower storage gadgets.

There is not any noticeable distinction in efficiency throughout the drives examined.

The Elder Scrolls IV: Oblivion Remastered

The Elder Scrolls IV: Oblivion Remastered modernizes the look of the unique sport with improved visuals. Built on Unreal Engine 5, it makes use of Nanite virtualized geometry, Lumen international illumination, and digital shadow maps. This is an open-world sport, and our first UE5 title is examined on this article.

None of the SSDs we examined reached 100% peak utilization and common utilization is extraordinarily low, too.

As is the case with many of the video games we have now examined, the SATA SSD holds its personal and there’s no distinction in efficiency throughout all the drives.

007 First Light

007 First Light

007 First Light is a just lately launched sport that makes use of DirectStorage. In a recent interview, the builders at IO Interactive revealed that the real-time degree streaming system within the Glacier engine was redesigned for 007 First Light. The new system makes use of dynamic loading and unloading to permit for seamless transitions between sequences.

It’s clear that this new streaming system doesn’t place a heavy burden on storage gadgets.

Given the I/O exercise on this sport, it’s not shocking to see that each one SSDs we examined carry out the identical.

F1 25

F1 25

We included F1 25 as a result of it displays increased peak bandwidth and utilization than most video games. The sport’s high-speed driving requires speedy streaming of trackside property, because the setting adjustments rapidly and the participant covers massive distances in very brief intervals of time.

The sport displays increased peak and common bandwidth than lots of the video games we have now examined, however it’s nonetheless not sufficient to actually stress a SATA SSD.

Once extra, all the drives present equivalent efficiency.

What About the Visuals?

What About the Visuals?

Many readers could also be questioning if enjoying on a SATA drive resulted in any visible anomalies, akin to slower loading textures, further pop-in, or different visible artifacts. We didn’t discover any such points within the 11 video games we examined. There are some video games that exhibit pop-in, however that’s constant throughout all storage gadgets. All of the drives we utilized in our testing offered an equivalent visible expertise.

The Verdict

The Verdict

Out of all of the video games examined, solely two confirmed measurable efficiency variations between SATA and PCIe SSDs: Forspoken and Ratchet & Clank: Rift Apart.

In Forspoken, shifting from a SATA SSD to any PCIe SSD – no matter technology – resulted in a big enchancment in 1% lows.

Ratchet & Clank: Rift Apart confirmed extra nuanced outcomes. During the portal sequences at 1440p and 1080p, common framerate and 1% lows have been barely increased on the SATA SSD, as slower loading elevated the time spent contained in the portals. Since the portals include much less on-screen complexity, framerates are naturally increased inside them. However, at 4K decision, PCIe SSDs delivered higher 1% lows. Outside of the portal sequence in regular gameplay, there was no measurable efficiency distinction between any of the drives.

Across all different titles, PCIe SSDs offered no significant efficiency benefit, and there have been no observable variations between PCIe generations. In the overwhelming majority of video games examined, a SATA SSD delivers comparable efficiency.
