I have a good pc, but games still lag, what can this be?


Nov 20, 2012
Hello, i think by myself i got a pretty decent gaming pc, but yesterday, when i played assasins creed 3 i couldnt run it on max settings.
i checked Can u run it, requirementslab, and the bar was reaching fast.
this are my system specs.
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz (running it on 4ghz).
8 gig 1600mhz ram ddr3
Microsoft Windows 7 Ultimate Edition Service Pack 1 (build 7601), 64-bit
amd radeon hd 6990 4gb graphic card
and over 1 tb free space.
850Watt power supply.
i really dont know whats wrong, but used drivesweeper to uninstal graphic drivers, and updated them after to the newest.
reinstalled windows 7.
maybe other people know what can be wrong, i cant find more solutions to try, thats why im posting here.

ps dissapointed gamer :p
Is it only one game or others as well? Double check your temperatures and make sure your antivirus wasn't running a background scan or something like that (reboot a few times and try the game again)
