Lost Soul Aside – DLSS 4 & Ray Tracing Benchmarks

Sony has just released the third-person action game, Lost Soul Aside, on PC. The game is powered by Unreal Engine 4, and it supports both DLSS 4 and Ray Tracing. Thus, I’ve decided to benchmark these two features first. So, let’s see how the ray-traced version runs on PC.

For these benchmarks, I used an AMD Ryzen 9 7950X3D with 32GB of DDR5 at 6000Mhz, and an NVIDIA RTX 5090. I also used Windows 10 64-bit, and the GeForce 581.15 driver.

Lost Soul Aside does not have a built-in benchmark tool. So, for our benchmarks, I used the first market area. This area has a lot of NPCs. So, in theory, it should be one of the most taxing areas.

Lost Soul Aside has three different settings for Ray Tracing: Low, Medium, and High. And, even at Native 4K with Ray Tracing High, the NVIDIA RTX 5090 is able to push over 60FPS at all times. Sadly, there isn’t any major performance boost between Low and High Ray Tracing. This is most likely due to CPU/RAM bottlenecks, as the RTX 5090 was not used to its fullest at both Medium and Low RT.

Turning on DLSS 4 Quality Mode did not really boost performance when using High RT on our PC setup. If you want higher FPS, you’ll need to turn on DLSS 4 Frame Gen. When we did that, our framerate jumped all the way up to 180FPS. Using MFG X3 and MFG X4 also gave a big performance boost.

But what about the image quality of MFG X4? Well, the good news is that there are very minimal visual artifacts. Here are two screenshots I took when I was moving the camera as quickly as possible with my mouse DPI set to 3200. These images are from a worst-case scenario. You won’t be moving the camera as much as I did. Still, this is an ideal stress test to see how MFG can handle very fast movements.

In theory, things should be great, right? Performance seems to be great with Ray Tracing, even at Native 4K. Sadly, though, RT introduces noticeable stutters in this title. This is something we’ve seen in other UE4 games that have Ray Tracing, too. So, I don’t believe these RT effects are worth the extra stutters, especially if you are sensitive to them.

Another big problem is the main character’s running animation. For some reason, Kaser looks like he’s stuttering every time he runs. You can really see this at the 3:57 mark in the video. The camera also moves in a jerky way. This has nothing to do with DLSS 4 or Ray Tracing. It happens even when those are turned off. So, the devs definitely need to fix this.

Overall, Lost Soul Aside can run at high framerates on powerful GPUs, even with Ray Tracing turned on. However, Ray Tracing also causes some stutters, so it’s a bit of a trade-off. Some players may turn it on for better visuals, while others may turn it off to keep things smoother. On the bright side, DLSS 4 appears to be excellent. I didn’t notice any input lag, and visual glitches were kept to a minimum.

Enjoy!
