Windows 11 has problems with the slowdown of games for those gushing AMD Ryzen processors, arsenic was officially inveterate parting calendar week – but a new patch from Microsoft has reportedly ready-made these issues even worse.

Unfortunately, the very first temporary hookup Tuesday update for Windows 11, which arrived yesterday, seems to have thrown more spanners in the works when information technology comes to the dua of bugs – which includes a hob with L3 cache latency being much higher – dragging gaming performance down encourage. (Note that this patching wasn't expected to cure anything play-related – but it certainly wasn't expected to exacerbate the situation).

How to fix Windows 11 problems
We'll show you how to build a PC

This is according to Tech PowerUp, with the tech site performing tests using a Ryzen 7 2700X CPU which had an L3 cache latency of 10ns originally, which was driven up to 17ns aside the cache bug, and is like a sho way worsened after Microsoft's new cumulative update was applied. In fact, latency now stands at 31.9ns, so the problem is not far off doubly as dreadful (and three-base hit the original latency).

There is some good news in the report, though, viz. that AMD has tending U.S.A release dates for the patching of these two bugs, reported to a post on Reddit.

The L3 memory cache problem has already been resolved by Microsoft – we have so seen references to the cures in dev builds of Windows 11 going back a month – and the fix is solidification to constitute deployed on October 19.

We'll comprise waiting slightly longer for the other issue to be kicked into allude, which is a glitch with UEFI CPPC2 impacting some apps and games, but the fix is expected on October 21. Note that these are targeted dates, indeed it's non inconceivable that last-minute problems could pop up to delay things a bit further.

Analysis: A stinging problem made worse – just don't rush or botch the result, Microsoft

It's an alarming measurement to see the cache rotational latency empale up even farther – quite dramatically, really – afterwards a round of Windows 11 patching has been applied, and obviously this could leave alone some AMD processor owners even Thomas More unsuccessful with their gaming performance.

That same, this is just a idiosyncratic test scenario of one particular Ryzen cow dung, and we can't put too a lot emphasis connected it as a consequence. Separate folks Crataegus oxycantha not find the same happening with their PCs, and so there are whatsoever posts happening the above linked Reddit thread where gamers are locution that they're not experiencing any pronounced difference with their carrying out levels.

The level of touch is, course, supported a whole load of variables, non just including the demand ironware configuration of the PC, but also the game being played (and what settings it's running with).

As AMD made clear in its initial admittance of the lay away latency problem, the big performance hits – of up to 15% drops in the frame rate, apparently – are what it describes as 'outliers', so the majority of systems shouldn't see this kind of sluggishness.

It's likely that these bigger slowdowns pertain to those flying the likes of Cesium:Depart at 1080p and commanding frame rates, with a high refresh value proctor for ultra-smooth gameplay (AMD mentions esports shooters specifically Eastern Samoa pip-case scenarios). Of course, these are the rather competitive gamers WHO are going to be pulling their tomentum out at true a slight lag, let solely a drop that's in double figures.

Other folks more possible to see their performance levels wonder-struck include those running 8-core Ryzen chips, or CPUs with plane more cores than that (and TDPs of over 65W), as AMD previously clarified is the shell with the UEFI CPPC2 pester.

Technical school PowerUp makes an unputdownable point about the urgency of these fixes, not fair-minded because of the potential high levels of slowdown that an apparent nonage is encountering, but because of the at hand launch of Intel's Alder Lake chips.

The new 12th-gen processors from Intel are expected to arrive initially of November, and are adjusted to work with Windows 11. That means reviewers will be benchmarking in that Osmium, and doing the same with AMD Ryzen 5000 processors to compare and contrast operation. Sol, if Windows 11 results with Ryzen chips are being knocked off kilter by these bugs, it's easy to see why AMD is precise keen to start the fixes out there – to prevent Alder Lake looking even better than it should exercise (with rumors already indicating it's a solid performer).

Even so, if Microsoft is rushing a fix direct for next week under pressure, well, we can only view the record of unstable Windows cumulative updates that fix something while breaking something other, and hope that this won't be a scenario we'Re again facing future in October.
