Configure DLSS Super Resolution presets (K/L/M) with GPU-based recommendations
RTX 20/30 → Preset K recommended, RTX 40/50 → Preset M or K
Preset L is heavier and may reduce performance

Blacklisted Games
The list of games that are not supported (blacklisted) is now maintained in a separate repository as a CSV file. This allows for easier updates and potential future expansion of game-specific information without requiring changes to the main application. You can view the current list of blacklisted games here:
Use their own version of DLSS for testing (e.g., 3DMark)
Replace the DLL when the game is booted (e.g., Warframe)
Are using a DLSS version <2.0 (these are non-updatable)
Have specific compatibility issues with updated DLSS versions
The games that are blacklisted can be disabled manually by clicking the "Manage Blacklist" button in the GUI. This will allow you to skip games for whatever reason.
Restoring modified DLL's
You can find these in the Backups tab.
