Thank you for your reply, but I have tried a lot of methods for the week.
The game looks like not optimized for such resolutions or badly optimized.
In 1920x1080 resolution the game seems to understand and upscale by itself, but its not my native resolution now, and all becomes jagged and awefull in game and in Windows.
Really, I tried a lot of things, even go to support, but they seems cant help me, only if optimize it for high resolution.
