That's because the gamma setting changes your system gamma, not the game itself, I included a wrapper that fixes this.

Open DxWrapper.ini and set LimitDisplayModeCount to 0

Oh nice, glad that It helped lol, such a simple solution

It's a bit hard to troubleshoot your issue since it doesn't happen in neither my main PC and Laptop with igpu, my suggestion is turn off Windows DEP, rename the game executable and run it as administrator

Could you try this debug version of DxWrapper a little quick? Same procedure as before, access the options menu, exit and sent me the log files, try with HandleExceptions enabled and disabled, sent me the two logs

I can't access the link, could you make it public please?

Ok, I suspected that this would happen, enable HandleExceptions again, on the dxwrapper configuration file set DisableLogging to 0, open the game and access the options menu, then exit it. a dxwrapper log file should be created, sent it to me so I can tell what's crashing the game.

Open dxwrapper.ini, disable HandleExceptions and enable the SingleProcAffinity option, maybe this could be a multi-core issue?

You can delete glide2x.dll and use Direct3D then.

Open dgVoodooCpl.exe and change the output API to Direct3D 12, the last option. Then tell me if the options menu text is fixed

That's really weird, I'll suggest you to use the Glide renderer then, download this and extract to the game folder, select the 3DFX custom driver when prompted:

The fix the disappearing level geometry, set the fog distance to medium

What glitches you're encountering?

Just unzip, no Disc needed

You're using the Steam version right? If so, delete TronLauncher.exe and rename Tron.exe to TronLauncher.exe instead

Does deleting dinput8.dll fixes it?
