How to Enable DLSS 4.5 in Forza Horizon 5
If you notice 'trailing' behind your car, switch DLSS Preset to Preset C using DLSSTweaks (safe for offline/free roam, risky for competitive).
Is it Safe to Swap the DLL?
For single-player games like Forza Horizon 5, updating the nvngx_dlss.dll file to version 4.5.10.0 is generally safe and can improve image stability, reducing ghosting and shimmering compared to the stock DLL file. Always use DLSS Swapper to backup your original file first.
