Disable Incompatible Software

Certain software programs, such as overlay programs, recording software, or performance boosters, can conflict with Modern Warfare 3 and lead to the "GPU Not Supported" error. To troubleshoot this issue, you should temporarily disable these programs while playing the game. Here's how you can do it:

1. Identify any software programs that are running alongside Modern Warfare 3 and may be causing conflicts.

By disabling incompatible software, you eliminate any potential conflicts that may trigger the "GPU Not Supported" error in Modern Warfare 3.

 Tweak the HOST File

Sometimes, the "GPU Not Supported" error can be caused by incorrect information retrieved from certain websites. To prevent this from happening, you can tweak the HOST file on your computer. Here's how you can do it:

1. Access the HOST file on your computer. It is usually located in C:\Windows\System32\drivers\etc.

2. Open the HOST file using a text editor such as Notepad.
