Windows 11 23H2 update reportedly slows down gaming performance for some but there does seem to be a somewhat complicated fix

pcgamer.com:

Windows 11's 23H2 update has been out for a little while now, but some users have reported a noticeable drop in gaming performance since installation, which seems somewhat fitting for an update released on Halloween. If you've yet to install it, the good news is that Microsoft has currently placed the update on compatibility hold for a different issue which hopefully means both problems might be fixed by the time it becomes available again. 

For those of you experiencing this issue and don't want to rollback to a previous version however, there is a supposed fix. The bad news is, it's a little complicated.

Via HotHardware, Reddit user BNSoul reported that their system slowed down in benchmarks by around 5-8% with the update installed, and their games were also affected by random stuttering that was fixed by rolling back to the previous update version, 22H2.  

After contacting Microsoft they were given a set of instructions that supposedly fixed their current version of 23H2, but the method is rather involved. We reached out to Microsoft for any comment or confirmation on these instructions, and will update this article if we hear anything back.

A quick PSA: While I've tested this method personally and can confirm it doesn't seem to have broken anything on my machine, I seem to be one of the lucky ones that didn't see any performance drops with the 23H2 update. As this involves changing BIOS settings and messing with Windows Defender, which for many users may be their primary line of defence against malware and viruses, my advice would be that if you're comfortable with your PCs performance it's probably best to wait until Microsoft releases an official update fix. 

Try at your own risk.
