I found this nice mod for remastering the graphics for the game. It upscales the textures and includes and upscaled UI for higher resolutions. I am playing the game @4K and it is working finde. You don't need the executable if you don't want additional features like EAX.

Thanks for sharing this. I was actually just wondering if there were any mods available that enhanced this game. You can find them for a lot of older games and they definitelly improve the gameplay on modern computers.

i have the problem my game crash at mission 2 with the mod...

From the looks of it I would say the game did run out of memory.
I can not tell exactly where.

That could be caused by a shader or texture or other modifications made by that mod.
Can you check if it is working by using the savegame (EF2\base\save\yourwindowsusername\) in a version of the game without the mod ?

I suggest looking at my post in these forums for this game...it does a better job at making the game more of a remaster than the mod this thread links to

My post even fixes practically every graphical bug the game typically suffers from while also greatly increasing the graphical fidelity all while barely impacting performance

In my case it helped to delete all ...Kuzja.pk3. files.in base folder of the game. In other cases you have to edit the EF2_Remaster.ini to the follow: ENABLE RS = FALSE or ENABLE EAX = FALSE. Or use the original exe tho start the game.
