When I alt-tab and try to go back into the game sometimes it would take sometimes before it would let me. Most of the time when im back into the game from alt tab then the game would be running again as if Im just waiting for it to resume without alt-tab. I run just one monitor and full screen.Im going to try and uncap my fps and see if it stop it from happening. Its just so random that some days it wont happen and other days it does.With most games I play, gpu is always at 99% load( fps uncap) I just cap fps with FFXIV b/c I like to afk a lot and don't see the need to run the game more then 60 fps. Helps even lower the heat from gpu.
