sometimes when i alt tab, my mat_monitorgamma resets to 2.2. checking console it still says 1.6. i have to change the value to something different and then back to 1.6 to get the high gamma back. Now and then this also happpens when i launch tf2 out of the box. Another issue that comes with it, is that it drastically drops my fps to bellow 140.
What ive tried so far:
New clean tf2 install
New Nvidia Driver Install
any help is appreciated pce
edit: using mastercoms Low
