The max resolution I can use is 1200x800. At higher resoution I get an access violation error.
Tried to change the AN2 Data file. But it isn`t working with the mod, also.
The log.txt shows:

GFX Information
---------------
resolution : x:640 y:480 d:32 v:1 m:65535 t:0 a:0 w:0
driver : nvldumd.dll

whql signed : no (warning: the current graphic card driver is not whql certified!)

Is there a way to fix it that I can setup the resolution to UHD? Or WQHD?
The current driver is wqhl signed and the maximum resolution of the 2080TI Card is more than 4K.

Have you tried dgVoodoo 2?

Just set a resolution which keeps the GUI in the game usable and set your desired resolution in dgVoodoocpl.

This tool helps!
It is a good tool to configure the resolution in the game as it should be.
Unbelievable, I searched so long in the www and found nothing.
It is easy to understand, thats good.
All the best to the Netherlands!!!
