Hey there guys!
Right now im playing 2 games on daily basis, unfortunately both are bad optimized. I have Lenovo Y50-70 with pretty good components. It should run games with no problem. Anyway im playing Guild Wars 2 and Rainbow Six: Siege. I have FPS drops in both of them. I did a research saying that i should disable Hyperthreading for Guild Wars 2 because its not good optimized, its CPU demanding and running on DirectX 9, etc etc. After this research i found out article which says that even Ubi games might be problematic when it comes to HT so im wondering if FPS drops in this 2 games dont have same problem. And that would be HT.

I was in BIOS but theres no option for me to disable HT :( So i think i would have to at least try to do that with Set affinity through Task Manager. I have i7-4720HQ but im not sure which cores should i disable/enable there. I have 8 (0 - 7) options there. Which ones are actual cores and which one that virtual? Is it even possible to find that out?

Thanks for all answers

Don't disable hyperthreading. I've played both games on hyperthreaded CPUs and in the vast majority of cases, the difference with it on and off is minimal, but everything else you do on your PC will suffer from disabling it. Also, the Windows scheduler is HT-aware, and will not load up a "hyperthread" before filling up all of the real cores first, so setting affinity should do nothing. Most likely your drops are just related to having a low-clocked mobile CPU and a GPU that's *relatively* weak. Guild Wars 2 will dip even in areas with an overclocked desktop 7th generation CPU, so it's no wonder you're seeing dips with yours.

Question: Does lowering your graphical settings prevent the frame drops in these games?
