A game you programmed yourself? A game you have the source code for? A game you bought but for which you do not have the source code?

Your question is so imprecise (being posted in a programmer’s forum) that it’s impossible to give a good answer. Also it’s quite unrelated to CUDA.

Nvidia support told me to go here and ask how to resolve my problem.

(1) If NVIDIA support told you to take your problem to the “NVIDIA forums” and you picked this particular sub-forum on your own, revise your choice. Best I can tell your issue has no connection to CUDA programming whatsoever, so your chances of getting a helpful answer are practically zero.

(2) If NVIDIA support specifically told you to post your question in this particular sub-forum, NVIDIA support staff need re-training. Your question if off-topic here.

but where can i find help? they gave me this forum.

Consider using Google to find places for help.

There’s a scriptable tool called AutoHotkey

it gives scripted access to many nVidia specific functions, such as Digital Vibrance control

for brightness controls they recommend this:

I haven’t found anything to adjust contrast yet
