These are the best overall settings for Lost Soul Aside, ready to be dialed in on Steam Deck and Steam Deck OLED.

Lost Soul Aside is an extremely CPU-intensive game that faces micro-stuttering on older CPUs. The Steam Deck utilizes a Zen 2-based CPU design, which aligns with the game’s recommended CPU requirements. Even with that, there is a chance that you will be CPU-bound. However, the settings below aim to address the CPU-bound issue and, with the help of Lossless Scaling, provide the optimal way to play the game.
Please note that if you do not own the Lossless Scaling software, you may want to consider purchasing it, as it’s reasonably affordable and performs well in situations like these. As an alternative, you can try Intel Xess with the balanced profile. Just so you know, the version used here is Xess 2.0, which uses AI for upscaling. As a result, your performance may be impacted, so your results may vary.

Lost Soul Aside – Best Settings for Steam Deck and Steam Deck OLED

The Steam Deck and Steam Deck OLED have similar hardware, except that the OLED model features a higher-quality screen and a die shrink in the CPU. The GPU used in both devices is the Vang Gogh (Steam Deck) and Sephirot (OLED). It features RDNA 2 GPU design with 8 CUs, for approximately 512 unified shaders.
Performance-wise, it’s inferior to the RDNA 3-powered 780M in the Z1 Extreme; as a result, the base resolution is lower. Below are the settings that you should use as a starting point. Depending on your FPS tolerance and visual tolerance, please make the necessary adjustments.
Very Important: Please watch the guides on how to set up Lossless Scaling with Decky if you haven’t already done so. Once you have it set up, use a base FPS of 30 and apply frame generation at 2x.
