Question How to fix this texture shimmering / flickering in games?

May 13, 2021
I've seen a lot of people having this issue in different forums with no solution. But I found a specific "solution" that works but isn't ideal and might lead to a real solution.

I'm on a 2560x1440 display and lights / people in games will occasional flicker and shimmer. Sometimes a lot and its super annoying.

I found that dropping my resolution to 1920x1080 in games fixes the flickering (looks like crap tho).
I also found that moving the render scale up 20% or down 20% or more, also completely stops the shimmering and flickering.

Knowing this is there any reason you can think of why its only shimmering on my native resolution?

I don't see how it could be a cable or graphics card issue if it works fine at higher and lower resolutions..
