If you see the 8000 value displayed for either power limit then the BIOS is not setting your CPU up correctly. after booting up and before running anything, run CPU-Z, create a report and check this register. The 8 means that this power limit is enabled and the 000 means the turbo power limit register is set to 0 Watts. If you see the value 8000 at these two locations within that register, that is the problem. Ok I checked and my GPU clocks don't change when I come Back to the game after Alt-Tabbing I'll also check to see if the clocks get reduced when I tab back in and report it here too.

I'll look into the game priority in task manager and report back. (I do have gsync enabled for both windowed and fullscreen mode) I guess gsync works better with fullscreen. I do have slightly less performance overall than fullscreen. I can alt-tab with no loss of performance when I tab back into the game. **UPDATE** I went ahead and selected fullscreen borderless window mode for both call of duty modern warfare and black ops cold war and it seems to have fixed my problem (mostly). Only a few titles, especially Black ops Cold war and Modern warfare I just played Borderlands 3, and B元 doesn't suffer any performance hit when I alt-tab out and back in.

I remember reading on the web that apprently it might have something to do with gsync, although I don't understand why The whole game feels very glitchy and hitches a lot when I come to back to it after alt tabbing out. Click to expand.ok I checked and my GPU clocks don't change when I come Back to the game after Alt-TabbingĪs for the priority I set it to High priority manually and my FPS is still about 40% less than when I DON'T alt tab out of the game.
