Hello, as advised, i am putting up a bug report about blurry display rendering.
Based on https://us.forums.blizzard.com/en/wow/t/slightly-blurry-display-rendering-since-pre-patch/1905668
Some of us are facing what appear to be a blurring of screen image quality (in DX12) since the prepatch. Features appear to be softer and not sharper and happens in DX12 since the prepatch. Some of us have had no other options changed and immediately noticed the disparity of screen quality. For some of us, switching to DX11 resolved the issue. However switching back to DX 12 brings back the problem again.
Putting a report here for blue Eyeballs for additional assistance. Perhaps some sort of beginning guidance would help. Please let us know what to provide.
