This is the weirdest issue i find in a game! My Skyrim is in Ultra settings and with my realively old ATI HD4870X2 card works "on the edge" 20-24 fps at 1920x1200. Now here the weird thing: i ALT-TAB on windows (maybe to open a website or so) then re-ALT-TAB to the game... OH MY GOSH!!! THE GAME ALMOST TRIPED HIS FRAMES PER SECONDS!!! Now i go even at 60 fps or more! (i disabled frame limiter) And... ops... crap i died. Reload the game... what?? SLOW AGAIN?? Alt-Tab out and in... 60fps. Why this behaviour? This also happen when i load in a new area, the games slows, I Alt-Tab out and in then go fast again. The real question is: Can i keep Skyrim go fast without minimize it to windows every time??
