On a Steam Deck (RDNA2 iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Until Dawn runs at roughly 46 FPS at 1080p with our optimized settings — up from about 23FPS with everything maxed. Here's the configuration and what each setting costs.
The Steam Deck (RDNA2 iGPU) is a handheld graphics card with 4GB of VRAM, and Until Dawn is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is playable at 1080p — about 46 FPSwith FrameCoach's optimized settings, a clear jump from roughly 23 FPS with everything on High.
Across resolutions you can expect around 46 FPS at 1080p and 28 FPS at 1440p, dropping to roughly 16 FPS at 4K. Until Dawn offers ray tracing, but the Steam Deck (RDNA2 iGPU) isn't built for it, so we leave it off. With only 4GB of VRAM, keep textures a notch below max in Until Dawn at higher resolutions to avoid stutter. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 23 | 46 |
| 1440p | 14 | 28 |
| 4K | 8 | 16 |
