i updated my Windows to Windows 8.1 64 Bit and i'm very happy that it works with my Radeon HD 5770.
Everything works fine, but i have some laggs/fps drops in the game "Counter-Strike Source". I'm playing "Medal Of Honor" too and i think i don't have laggs there.
Is there any solution to fix that? I already downloaded the newest driver for Windows 8/8.1 64 Bit (Not the Beta-Version).
Could it be that the Beta-Version fix that? I don't want to install a beta, so do you know anything new about a new version?
I hope you can help me, sorry for my bad english
Best regards, Liptoic
