Hyperthreading off = stutters off.
 

S!

Simple like that. It worked for me. Finally a more fluid flight, but near clouds and deck flight, still there´s a hit, not so bad as before. Everything in High but Forrest Medium and vsync, shadows and grass on. Some mods too. Hope helps other people.

SP!

This works. Never played ArmA or CloD with HT on. You can disable it in bios btw.

always was.....HT OFF when gaming...

I dont have such function in my bios - Asus P5KC? I got Q6600@3.2 Ghz and these cpu dont use HT?

BTW i have a lot of stutters/freezes in CLOD - expecially over cities and when other planes is coming. I dont know how it was before patches beacuse dont try CLOD too much, now i got new ATI HD 6870 and even with quite good fps i got a lot stutters??

Try reducing texture quality to high from original, landscape shading to medium, SSAO off, and excluding both Steam/1C and Documents/1C directories from antivirus real-time shields. Check out link #8 in my sig just in case.

How does this work?

You switch off Hyperthreading at BIOS?

Will the system (Win7-64) boot normally after the change?
(I remember hearing of problems with WinXP and the first generation of PIV HT CPUs after such a change...)

~S~

Always been off..but still a few hiccups on beta2 here v15866 , not very much; but there

Yes, disable it in BIOS. Win 7 will boot normally.

AMD here, always "off"! LOL!

Same, here!!!!:grin:
