Thanks for your help. These commands fixed it for me: gxRefresh <your monitor's maximum refresh rate> e.g. gxRefresh 60 (for 60hz monitor) M2Faster <CPU physical cores - 1> (Dual-core = 1, Tri-core = 2, Quad-core and above = 3) Here's the link: http://forum.nostalrius.org/viewtopic.php?t=1100&f=32

They are all running at ~2.5 GHz average. In fullscreen mode it's a little higher, in windowed mode a little lower.

Can MSI Afterburner show that information or do I need additional software?

I've got MSI Afterburner installed. Core 1 runs at ~70%, the others are running on a lower percentage. None of them is getting hotter than 40°. I am constantly watching my FPS via CTRL + R in WoW and it's sitting at 60 or slightly above at all times. If I do not move my character there is no stuttering. But as soon as I start running around the screen is stuttering just as if the FPS is dropping. But it isn't.

Hello Guys, while running around with my character the game is stuttering. It's no FPS issue though since the FPS are at 60 and above constantly. I already tried windowed mode, disabling vertical synch and using compatibility mode. With the stuttering the game is really unplayable. Im getting headaches from playing like this. So, any ideas? Thank you in advance. CPU Intel Core i5-4750 @3.20GHz
