Playing in 4k, some issues

[ZeusBrocken]

I am trying to run War Thunder in 4k because on native 1080p I have some texture problems like flickering trees and bushes. This is a major issue lots of people have. But when upscaling it to 4k, all these problems vanish. But now for the new issues.
My Mouse is stuck to the 1920x1080 resolution, so I cant pan my mouse over the whole screen and my HUD is way too small when in Battle.

Is anybody here playing in 4K (I highly think so) and do you have any tips on this?

I play 2560x1600 [native] without any problems, but I play PC on a WQHD monitor.

i have the same issues and played on 4k for a good while but i was so annoyed with the small hud and texts so i switched back to 1080 and go used to it again. Still very annoying with the flickering trees/bushes and other stuffs and that i know i see everything much better on upscaled 4k. Also i have min80fps on 1080p and usually 100fps+ on max settings wich is more a joy for the eye than 4k with lowered fps imo.

Exactly my thought. I am playing on 1080 maxed settings with around 170fps, on 4K I get above 60fps, but it feels like 30, dont know why. The flickering etc is really annoying but its better than some crappy 4K settings
