FidelityFX FSR2 v2.2.1

FidelityFX FSR 2.2.1

FidelityFX FSR2 v2.2.1 is a minor update that increases image quality in a few more cases and fixes several reported issues.

The application-side API has very minimally changed, so updating to FSR 2.2.1 from 2.2.0 will be very simple. If it's the first time you're looking at FSR 2.2, please pay particular attention to the changes around mask generation to get the best quality upscale.

We aren't able to get to every GitHub issue filed, but we do read and appreciate all of the feedback. Thanks for helping us make a better FSR 2!
