I run a higher end rig with an i7 2600K. When ARMA 3 is loading (with the main menu not reached yet), CPU load indicated hyperthreading is working as intended as all 8 threads are running fast. After the game leaves the loading screen, and from here on out, hyperthreading apparently turns off and only the 4 cores are utilized. That the GPU/CPU usage is low has been reported, but I have not seen anyone mentioning this specific problem. Does this happen for any of the other i7 users? Also, playing around with -cpuCount and -exThreads does not enable the hyperthreading.

What chemical reaction are you speculating, good sir? Even 130 F (you should specify you scale in the future) could do very little to a chemical reaction for a compound that has stability form 20-400 F. Good luck with your understanding of the problem. Better yet, you messed up applying the paste and finally (FINALLY) you got it right (HIGH FIVE BRO!).

Is this issue worth opening a feedback post on? And, ugh... Should we not report any bugs with the engine? What is your point? Keep the low effort posting away please.

Tested this on another rig with an i7 and it has the same problem. And to clarify again, I am not concerned if HT will or wil not improve performance, I am pointing out that it is not even enabling.

I strongly disagree with your post. This is a fault of the game. Read through the thread, many users still suffer from low GPU usage even on Low settings (this is enough to dispel your argument). However, what you say about ultra, is valid.

Thanks Tankbuster, it's good to see I'm not the only one with this specific issue. However, see below, some 2600K users see all 8 threads running (but still get bad performance). Quoting Tintee from the sticked thread. He has the same processor and hyperthreading works for him. What is going on here? "My overclocked 2600k is using all 8 threads in game with quite balanced peaks of 50% on each thread and hyperthreading is working fine. What stuck out most was that gpuz was reporting that the game used a max of 3069MB of video memory in the short 10 minute test i did running at 1920x1080 and most things maxed, but not all. I have a 4GB GTX680. I`m guessing most people run with less than 3gb gpus so this will surely have some negative effect on them? Also gpu max usage was 84%. I started gpuz AFTER the game had loaded and while i was in the game playing. In game fps is not great with a best of probably 40 fps and a norm of about 25-30 and extreme dips to as low as 18 fps. The mission was CO 40 air cavalry 1.1. But i notice wild variations depending on what mission i`m running. Some run really well and some seem to run like crap. All above was tested by me opening up a small server game. My performance is far better when on someone else`s hosted game, like when my friend runs it on his 5.1ghz, 6 core intel rig. He reports a similar experience to my own. I`m on the latest beta drivers from nvidia (314.14)."

I am not talking about any benefits from hyperthreading. I am pointing out it is not even working, at least in my case. Sure, the engine likes 3 cores, but the -exThreads option allows for hyperthreading. When I use it, it see nothing.

I noticed hyperthreading shuts off completely on my i7 2600K in game. CPU and GPU load when ARMA 3 is launched (start menu has not been reached). And, CPU and GPU load when ARMA 3 is playable. This is taken in a game of Wasteland. It turns out for my rig, I get great FPS in small online matches (DM's and such), as well as in singleplayer. In large multiplayer matches, the FPS becomes horrible. When you look at the first link, the CPU is fully utilized and all 8 threads are running. However, as soon as the game fully loads, hyperthreading gets shut off and only the four cores operate. I have tried systematically incrementing -cpuCount=# (#=1,2,4) with -exThreads=0, and have found configurations with only 2 or 4 cores running are more stable than with -exThreads=# (#=1,3,5,7). In all, this leads to a very slow, laggy online experience. I am an ARMA2 vet, and I had these issues with Insurgency and some Domination matches. Outside of ARMA, my rig runs all other games on high without any issue.
