Any body know how to fix this?

If your native desktop resolution is too high, the game will fail to start completely. If your primary native desktop screen is locked from fullscreen applications taking control (incorrect dual monitor setup) it will also fail to start. A few things you could try:

1.Backup, and delete the Efconfig file in your base folder completely. Try to start the game again.
2.Open the cfg file with notepad and find the line where opengl errors should be ignored(seta r_ignoreGLErrors "1") and change the value.
3.Launch the game windowed
4.Launch the game using a custom resolution in the shortcut target line.
5.Open the CFG file and find the following lines or add them
seta r_customaspect "1"
seta r_customheight "whatevervalueyouwant"
seta r_customwidth "whatevervalueyouwant"
seta r_fullscreen "1"
seta r_mode "1" <---- keep changing this number between 0 and 9 until the game works.

6.If you're on an Nvidia card - go to Nvidia Control Panel(not windows control panel) and where it says Display go to adjust desktop size and position. Where it says Scaling, uncheck aspect ratio - and set this to Fullscreen. Perform the scaling on your GPU. Check the box that says Override the scaling mode set by games and programs.

7.If you are on Windows 11, go to system > Display > Advance display and change your refresh rate at this location manually. Open the EFConfig file and set your max fps rate to the same value as the HZ refresh rate you've selected.
8.Toggle seta r_swapinterval value between 0 and 1. This is known as vsync (but not really vsync, it's sync every frame between gpu and cpu in idtech games)

can't find Efconfig or launch in a window

modifying autoexec.cfg to set the correct resolution like fullhd changing these lines
seta r_fullscreen "1"
seta r_customwidth "1920"
seta r_customheight "1080"
seta r_customaspect "1"
seta r_mode "-1"

then save and run the game

Doesn't work for me. I CTD.
