    nice video, noticed with the HT you got a couple of pausing stutters, very hard to notice, but it was noticeable, only a crysis 3.

    I find that BF4 needs ht but when i play NS2 i get way less fps drop with ht OFF, and that game only uses 3 cores, but bf4 uses i htink all cores. Its probably better to turn ht off with single threaded application and games but would benefit from it with multithreaded applications.

    I notice HT does help bf4 fps, uparking cores give me a 20 fps bump in max ultra 1080p 64 players, avg 90, rare low dips to high 50s, which is better than before, I'm sure I saw 48 once or twice with the cores parked.

    Hmmm ya i don't think the HT made the pausing stutters though. IT did the same think with the HT off. I dunno what causes it it might be some background softwares like skype and thx mate and i want to add that the ac unity was running on SSD and crysis 3 on HDD so it might have to do with the HDD or something why its suttering sometimes.

    Its the HDD for sure, something was loading/reading from the hdd, it only happened when you went into a new scene, I alawys found that alot of games microstutter when installed on a HDD as compared to be installed on a SSD.

    Leave it on. Intel has been working on HTT for 15 years, it's as efficient and mature as it'll get.

    yup i can confirm that it's HDD causing the stutters i moved the game on SSD and no more stutters

    With and Without makes little to no difference, just personally find more fluid performance without Hyper-Threading.

    Always said sense the first gen i5 that HT is primarily for creating video's and such and not for gaming... Look at the temps and performance boost with and without HT..

    With HT really doesn't make to much of a difference besides higher core temps. Without seems to run fine and cooler to boot. May just wait to see what Intel really has in store for 1150 socket and maybe later go to a i7 4770k but right now seems I picked a good choice going the i5 4690k

    I figured disabling HT on a 4690K would have no impact on GPU performance. CPU intensive tasks such as video encoding, Mandelbrot, and ray tracing, sure... but not games where the graphics card does all the heavy lifting. A side by side comparison of GPU usage charts, one with HT and one without would be a better approach to testing.
