open the setup.ini file in notepad.exe when Game Guru is shut down and change this statement:
hidelowfpswarning=0
to
hidelowfpswarning=1
Save the file and restart Game guru.
You will not see that message again till update. I make a few changes in the setup.ini file for my use and save a copy of them to replace the settings I want after update.
This works well.
