I also run a high end system and have been plagued by fps drops/spikes and the occasional screen tearing until recently. The suggestions I am going to put here I have got from other posters all over the web so will not be taking credit for it. CPU Affinity or CPU Binding: (This applies to CPU's that have more than 4 cores.)Processor affinity, or CPU pinning, enables the binding and unbinding of a process or a thread to a central processing unit (CPU) or a range of CPUs, so that the process or thread will execute only on the designated CPU or CPUs rather than any CPU. As mentioned by iLG, GW2 runs on Directx 9.0 which only focuses on 4 cores. If you have a processor with 8 cores or more, your system will more than likely be stuttering as Directx 9.0 is bouncing between these 8 cores.There is a way to subsequently get your system to use only 4 cores for a particular program.Load up GW2 -> Load up Task Manager -> More Details (bottom of task manager) -> Details (its a tab at the top) -> find gw2.exe -> Right click on it and choose Set Affinity -> disable cores 1-3-5-7 by un-ticking them (and all remaining cores after 7).You basically want to tell your system to run gw2 under 4 cores. There are applications out there that can set Affinity for programs permanently. Just google Setting Affinity Permanently. There is also a theory that turning off HyperThreading will also improve system performance. I havent tested this yet. Watch your systemTemperatures are a key thing to watch on your system. Software may be telling you that your system CPU is running at a cool 55C, however, that is usually the package temperature. Make sure you have software installed that is telling you what each core temperature is running at. You will be surprised at how 1 core can spike to 75-80c which will then cause an occasional throttle which then creates the stuttering. Know your settingsThere are a few great youtube videos that explain what each Guild Wars 2 setting does and how it effects your CPU and GPU. Do a search on youtube for optimize gw2 graphics and watch the video by SimNationTV. He explains all of the settings and how they are used, even down to how sound quality can effect your fps. My last one, which I found out recently, and made me giggle: Windowed Full ScreenI found that if I hoped from wp to wp in windowed full screen mode my fps would drop down to around 25fps and never recover. If I ALT-TAB to another application, and then ALT-TAB back to GW2, the FPS would recover and stay at a steady 100fps. Jump to another wp, and same thing would happen. If anyone can explain this, then please feel free. So these are the things that really stabilized my system, and I really hope this all help's some of you as I know how frustrating it can be. Cheers, Bumble.
