Windows 11- Fatal Graphics Error

[aceshot1000]

Have edited Battle and campaign resolutions in preferences file to match my computers resolution.

Have set game to comparability mode for windows 7, vista and xp, never worked. I even set my compatability to 640 x 480, ran in administrator mode and disabled wide screen support.

Have reinstalled the files. verified integrity and installed both 4GB VRAM Patch from Ntcore as well as Windows SDK. I also made sure to properly apply the patch to the .exe file.

I do not know what to do. The game worked on my old computer just fine with windows 10, but I have no idea how to make it work now. Any suggestions?

Fatal Graphics Error (Possible Solution)
Problem: First, this process seemed to resolve an error I was receiving when trying to launch Medieval II: Total War from Steam or the root .exe (Application type). I would get a black screen followed by a crash and an error message stating: "fatal graphics error."

Solution: Find Medieval II: Total War in your Steam folder; for most people this will be under the directory of: Local Disk (C:) -> Program Files (x86) -> Steam -> SteamApps -> Common -> Medieval II Total War
After you have opened the Medieval folder, locate the application "medieval2" and right click it. Select the "Troubleshoot compatibility" option. Follow the instructions and allow Windows (I'm running 8.1) to find a solution, it should recommend an option for running the game with Windows Vista (32 bit) compatibility. Select that option and choose to "test program." If it works, then it should launch the game immediately without any error. From there, you can go in and select your optimal settings for the game. From now on, you should be able to launch the game without any issues.

Hope this helps some people!
