This is an updated version of the Intel XeSS Supersampling plugin for The Witcher 3. Digitally signed by Intel and unaltered.

v1.3 of XeSS brings significant performance and image quality improvements, even compared to FSR 2. I now run XeSS exclusively on my AMD RX 6600 rig, and it has made a significant improvement in my experience. You can learn more about the improvements at this article on Tom's Hardware.

Installation: Simply install with Vortex as mod type "Engine Injector" or manually unzip in the root game directory.  I have tested this in-game and it works well.

I highly recommend you install this with Vortex, just in case you have any trouble with it. You can simply disable the mod and the original DLL from the game will be restored.
This mod will be updated when new versions of XeSS become available.

Disclaimer: This DLL was made by Intel, and I claim no ownership of these files. I am posting them here for convenience in updating the game.
