which version of DirectX is your game running?
(what number is your “mat_dxlevel” console variable set to?)

Well it’s running either dx 8, 8.1 or 9.1x

One time i put in the lauch options -dxlevel81, but soon after i deleted that command

“What should i set it to”?

try mat_dxlevel 90 then set model quality to high in advanced video options
