which games use hyperthreading?

Do you guys turn off or on hyperthreading?i only noticed difference in watch dogs..but by difference i mean more than 10%..i read than sniper 3 makes use of HT but i didnt noticed it..any other games that uses hyperthreading?i rather leave it off cause it saves 5-6C at least

 

If you are happy turning it off on games and feel it gives you a better power/performance ratio then do that.

 

yeah but im interested which actually games benefit from leaving it on?

 

I've heard BF4 can benefit from having it on. I don't know much about it but I think you will only notice a higher maximum framerate rather than your average or minimum.

 

Correct me if I'm wrong. But I've understood HT to also benefit gaming by alleviating medial background tasks while gaming, rather than robbing a whole core in the process.

 

Ive never really seen hyper threading effect a games performance for the worse. Loading up 4 cores and having them play the waiting game when it comes to execution is still more beneficial then working with 2 cores and running into thread over loading, and wasted cycles on cores waiting for its major thread to manage some i/o.

Dumit, keep in mind that hyperthreading is not an acceleration or an instruction set that needs to be supported by games. Visually to games and apps, it looks like your cpu has 4 (or 8. how ever many cores + hyper you have) cores. The game has no idea that they are a special type. The only difference is the execution phase is shared between 2 cores.

 

BF3/BF4 multiplayer and Crysis 3 are the only ones that I know of.

 

Crysis 3 might too.

 

I dont think any game benefit from HT atm.

 

Actually games benefit a fare much from it. Unlike say, video encoding or a program processing a block of data, a game is only responding to the player and situation at hand. There are many quiet times in a game where load is low (were talking milliseconds here, this is the time frame processors work in) and the processor could break off one core and work on the second.

 

Games that utilize more threads than you have physical cores do, although those are few and far between if you have a quad core or better. The i3 and mobile i5, which are dual core w/HT, will benefit the most. I've seen 30-50% FPS improvement with HT on in a desktop i3, almost matching a true quad core i5 in some cases.

 

IIRC, BF4 support hyperthreading, so does Watchdogs. Actually, assuming GPU isn't the bottleneck, BF4 scales quite nicely up to 6C/12T.
