I was playing Project Cars, I suddenly see that FPS indicator (Steam's in-game FPS counter) shows 30-32 FPS, previous time when I played the game it was solid 60 FPS (VSYNC) 72 FPS (no-VSYNC). So when I seen the FPS drop, I alt-tab to desktop to check my Radeon Settings (did not changed anything here), then return to game, and FPS is up to 60 FPS.
Its the same for all games I tested. Game loads at nearly %50 FPS drop until I alt tab It comes to normal 60 FPS.
Anything wrong with Multisampling ?
Using latest AMD (non-beta) driver.
