Should I disable hyper-threading?

[Connor Bittick]

Hear me out. I use Solidworks, which is a singlethreaded(I believe) application. I have several cpu bottlenecks in games that don't take advantage of all the threads. Shouldn't disabling hyper-threading allow those applications to make more use of my cpu? I use my gpu for rendering so there really isn't much that fully utilizes my cpu.

 

If you're wondering, I have a 1700x.

Why not test it your self?

 

But normally smt only help, and doesn't hurt very often.

I don't see how this would really benefit you, but you can try?

Well, I suppose it can't do any harm.

You do lose a little bit of single threaded performance, but it isn't much, and for games that properly utilize CPUs with 16 or so threads might see a loss of performance.

I concur with the others, if you have any kind of benchmark you can measure the performance with it won't hurt anything to give it a test. If it does something for you, great. If not, no harm done.

I'll be testing it tomorrow. I'll post what I find in case someone could find it useful.

Okay, so I've done some testing. A lot of 3dmark physics tests saw a 20-40% decrease in performance. Solidworks only slightly improved. GTA Story Mode improved from 87 fps(avg.) to 101. GTA Online saw no improvement. Subnautica effectively doubled in fps. The Witcher 3 didn't change, though I was only checking it to make sure I didn't create a bottleneck. CS:GO started stuttering, I had to disable multicore rendering to fix it. General applications like chrome and steam are much snappier now and my computer feels a bit more responsive. I have only seen performance drops in 3dmark, nothing else.
