Lost Soul Aside is a new action-adventure RPG released on August 29, 2025. The game has a visually immersive storyline, featuring rich animations, detailed characters, and ray tracing. It is moderately demanding on PC, requiring at least an NVIDIA RTX 2060 or an AMD RX 5700 XT GPU.

Lost Soul Aside looks and runs well on the Steam Deck, showing close to 60 FPS at 800p resolution. We've opted for a mix of Low and Medium settings to get a good balance of performance and visual quality. Moreover, AMD FSR upscaling has also been enabled and set to Balanced mode. This provides a decent boost in performance and visual quality.

The game looks less pixelated without upscaling but faces huge performance drops during demanding scenes. It even hits upwards of 60 FPS with the low preset, but also sees drops as low as 30 FPS. Thus, for a more stable experience, we must resort to using FSR, even though it causes some amount of pixelation.
