My mouse lags if I don't have it in windowed mode so I chose the fullscreen windowed mode in the f1_resdll file but it looks like it's 1024x768 instead of 640x480. I would like the original resolution because the words are pretty small but I can't change the resolution with the windowed fullscreen enabled. I can change it but it doesn't seem to stick. Idk what's going on. Windows 10.
