Yes, go to Wolf:ET - ETMain - Make new txt file. Put inside that file
seta r_primitives "2"
seta com_maxfps "125"
vid_restart
autoexec
Not sure do you need vid_restart but its good to have it. Next you have to rename your to Autoexec.cfg
In case of you don't see your file types do this: Go to your Control Panel - File Explorer Options - Un-mark "Hide extensions for known file types".
If you don't want to do all these things, here, take this file and put it in your ETMain folder. Added new FPS just in case if your FPS is set to 1.
autoexec.cfg
E: But most likely problem is in your GPU drivers. Download latest drivers.
