FSR 4.0.2 For RDNA 2 and 3

The official FSR implementation in Resident Evil 9 can often struggle with "fizzing" on fine details like hair or shimmering on distant foliage. This 4. 0. 2b INT8 build is specifically optimized for RDNA 2 (RX 6000/Steam Deck) and RDNA 3 (RX 7000) architectures, offering:

• []Superior Stability: Works natively with the latest official AMD Adrenalin drivers.

  []Cleaner Image: Drastically reduces ghosting and temporal artifacts compared to the launch-day FSR 3. 1.

  []INT8 Pathing: Forces the AI reconstruction path that was previously restricted to experimental wrappers, resulting in a sharper, more stable image on older RDNA hardware.

Installation Instructions

• []Navigate to your Resident Evil 9 installation folder (e.g., SteamLibrary\steamapps\common\Resident Evil 9).

  []Backup your original amd_fidelityfx_upscaler_dx12.dll file.

  []Download and extract this mod.

  []Place the provided amd_fidelityfx_upscaler_dx12.dll into the game folder, overwriting when prompted.

  []Launch the game and ensure FSR is enabled in the Graphics settings.

Recommended Settings

• []Upscaling: FSR Quality (for 1440p+) or Balanced (for 1080p/Steam Deck).

  []Sharpening: 20-30% (The 4. 0. 2b logic is naturally sharper than previous versions; high values may cause over-sharpening).

UninstallationTo revert to the original game files, simply delete the modded .dll and restore your backup, or use the Steam "Verify Integrity of Game Files" tool.

Compatibility

• []Hardware: Optimized for RDNA 2 (RX 6000 series, Steam Deck, PS5-equivalent PCs) and RDNA 3.

  []Software: Compatible with the latest Windows and Linux (Proton) environments.

  []Anti-Cheat: This is a standalone DLL swap and does not inject code, but as with all mods, use at your own risk in any potential online components.
