You can choose between "fullscreen," "borderless" and "windowed"
Ray tracing can be enabled separately. While the game always uses Unreal Engine's shader-based "Lumen," you may enable the hardware-accelerated version of Lumen here. This does cost some performance, but improves image quality a bit.
The FPS cap can be set to unlimited, 30 FPS and 60 FPS
Dynamic Resolution, when enabled, lets you adjust the render resolution automatically in-game, to reach either 30 FPS or 60 FPS
V-Sync can be disabled completely, there is no hidden FPS cap
The upscalers available are "None," "TSR," "FSR 1.0," "FSR 3.0," "DLSS," and "XeSS," but on Steam Deck you only have access to "FSR 1.0" and "TSR" unless you unlock "XeSS" and "FSR 3.0" with the "SteamDeck=0 %command%" launch option.
Quality has the usual upscaler quality modes, but no "native" setting, so no DLAA
The presets available are "low," "medium," "high," and "epic." The last option "custom" is required to adjust the settings. i.e. you can't customize settings when selecting "High."
The Advanced Quality Settings screen lets you fine-tune the rendering
Anti-aliasing options are "none," "FXAA," and "TXAA"
You may adjust the rendering resolution beyond 100%, to 150% and 200%
Motion blur can be disabled completely
Sharpening can be disabled completely, too
Test Devices
We tested the public Steam release of Silent Hill 2 Remake. The Steam Deck LCD was running SteamOS version 3.5.19, build 20240422.1. Our ROG Ally had the latest Armoury Crate version installed at the time of testing (1.5.11.0) along with BIOS 341.
