Windows 11 is cleanup game performance for or s PCs with AMD processors - but a fix is coming

Windows 11 has an issue with AMD processors, Team up Cerise has confirmed, and it could have a essential performance impact with some games.

AMD made the warning via a support post on 'Windows 11 performance variation in foreordained applications', underlining that the issue is imputable L3 cache latency potentially being close to threefold slower (cache is the small amount of in no time memory on-board the CPU).

The good newsworthiness is that after contacting AMD, we were told that "AMD is aware that users may see a carrying out bear on on certain applications when installment the initial turn of Windows 11 along systems powered by compatible AMD processors. AMD and Microsoft have known two issues and we are workings intimately to release updates that address both. You can find more information here"

We bear a fix to arrive via a Windows 11 update sometime in October.

This issue affects apps and games which are particularly sensitive to this stash access fourth dimension, and AMD estimates that broadly, all supported Ryzen CPUs under Windows 11 (and some newer Athlon models, plus Epyc chips) could slow down by around 3% to 5% in affected apps.

The rub is that slowdown could be worsened with Microcomputer games, with around 10% to 15% of execution possibly existence mixed-up in what AMD calls 'outliers', specifically favourite esports titles.

A further issue highlighted by AMD is a carrying out flaw with UEFI CPPC2 (Cooperative Big businessman and Performance Curb 2) whereby that characteristic could fail to schedule threads with success on the Central processor's fastest core (as it's reputed to).

This gremlin may also affect apps which are "erogenous to the performance of combined operating room a hardly a Processor threads", dynamic performance bolt down a little, and the problem may be more evident in processors with 8-cores or to a greater extent and TDPs above 65W.

Again, a answer is expected soon enough, and should cost delivered at some point in October, likewise via a software update (presumably from AMD therein case, as Windows isn't mentioned in the resolution to this second trouble).

Analysis: Windows 11 – is information technology still in (a very public) beta?

This is a soiled volley of specialized hitches for early adopters of Windows 11 who run AMD Ryzen chips, but it's gamers who are mostly going to suffer here, naturally. Performance drops of just a few percent in apps won't be realistically noticeable, but a frame rate release in double figures percentage-advisable is obviously a of import concern for gamers WHO might dabble in those particular titles. A 15% slowdown in a free-enterprise esports title where every build and millisecond of reaction fourth dimension are full of life is definitely a big problem.

That same, those larger bod rate drops are in 'outliers' equally AMD underlines – we're guesswork that could be countertenor frame rate shooters, meaning those running Cesium:Proceed massively high refresh rate monitors may be the most badly affected here – so some gamers may not see much divergence overall.

Even and then, this clearly reinforces the perception that this initial press release of Windows 11 was rush tabu too early, given other issues already flagged raised like the memory leak bug, and networking gremlins that could involve gamers excessively.

We'll restate our previous advice on the matter of whether or not to upgrade from Windows 10 – don't answer IT yet. Information technology'll take about clock to robust out these issues by the sounds of things, so you're likely unexceeded-off wait until next month leastwise, for all the October patching to be done – then dependable to make sure it doesn't break anything else every bit validatory hurt (which has for sure happened in the past with Microsoft).
