Disable Hyper-threading for Intel CPU or the AMD equivalent SMT in BIOS for stable performance

[本夹明SPenguin]

Before disabling hyper-threading, my frame rate dips to 40 frequently. Afterwards however, I am getting mostly locked 60 fps with my old GTX 1080 and i7-8700K (slightly OC @4.2Ghz).

Disabling hyper-threading also helps with AC Brotherhood, Revelations and AC Mirage's performance problems.

edit:
Dragon breath still messes up performance real good... it would seem that nothing can help with that.

Which os is in use ?
Windows 10 or 11 ?

I think an app needs to be purposelessly developed to take advantage of multi threading for it not to cause issues if subjected to hyper threading. Are not most if not all cpu's hyper thread enabled theses days ???.

Some games to utilise hyper threading, although there may be technical limitations with the type of data that's being processed that makes it not that advantageous, would need a clued up dev to break it down to fully understand myself.

Welp, Windows 10.
Settings mostly on max @ 1080p, have to knock down the grass setting to high, some foliage scenes are a bit intense.

edit:
Can't really maintain mostly Max, but can definitely do all high.

Yeah, multithreading is an annoying thing that helps in some games and hinders in others.
I'm betting it hinders more than it helps though.

Interesting. Was this Windows installed with this CPU or with a older CPU ?

Apps and games are not specifically programmed to use HT. HT is a hardware-side feature that is invisible to apps. If the app or game can dynamically create threads based on a CPU's thread count, it doesn't take into consideration which threads are "real" or "virtual" or in the case of Intel's 12th Gen and newer iCore CPUs, which threads belong to the E-cores. It is entirely the responsibility of the operating system to manage threads.

One thing I can point out though is that HT improves CPU efficiency at the cost of increasing temperatures since the CPU will be doing more work for a given processing cycle. In most apps and games this is fine, but for CPU-intensive apps and games, this can result in decreased performance if the CPU temperature hits BDPROCHOT and starts thermal throttling. Elden Ring is definitely one of those CPU-demanding games. Dunno about AC: Brotherhood.

This Windows was installed with this 8700K. Was Win10 out in 2017? I think it was installed when I built this PC back in 2017.
