The "Graphics" menu has presets, which are "Low," "Medium," "High," and "Epic"
Please do note that selecting any one of those profiles will set upscaling resolution to 66%! This will look terrible at lower resolution, especially when using TAA. I've manually set it to 100% for benchmarking purposes
You may disable motion blur by setting "Motion Blur Strength" to 0%
Sharpness defaults to 20%, which is a reasonable default
The upscalers available are "Off," "TAA," "TSR," "NVIDIA DLSS," "AMD FSR," and "Intel XeSS"
DLAA and FSR Native are supported, by selecting "NativeAA" in "Upscaling quality"
Both FSR and DLSS Frame Generation are supported. You may enable them separately, so GeForce 30 owners can use DLSS Upscaling with FSR Frame Generation
In addition to that, there are several options for fine-tuning performance on your system
You can choose between "fullscreen," "borderless," or "windowed"
The field of view can be adjusted between 70 and 110 degrees. I found the default of 90° a little bit too narrow and increased it to 100°
V-Sync can be disabled completely, there is no hidden FPS cap
The FPS limiter can be set to 30, 60, 120, 240 and unlimited
If the image is too dark for you, increase the Gamma setting.
Test Devices
We tested the public Steam release of "STALKER 2: Heart of Chornobyl" with the Day One patch applied. The Steam Deck LCD was running SteamOS version 3.6.20, build 20241030.1. Our ROG Ally had the latest Armoury Crate version installed at the time of testing (1.5.20.0), along with BIOS 341.
