Windows 11 has issues with slowing down games for those using AMD Ryzen processors, as was officially confirmed last week, but a new patch from Microsoft is said to have made those issues worse.
Unfortunately, the very first Tuesday patch update for Windows 11, which arrived yesterday, appears to have thrown more keys into the works regarding the pair of bugs that include a gremlin with the L3 cache latency being much higher, resulting in decreased gaming performance. (Note that this fix wasn’t meant to fix anything gaming related, but it certainly wasn’t meant to make the situation worse).
This is according to Tech PowerUp, the tech site testing using a Ryzen 7 2700X processor that originally had an L3 cache latency of 10ns, which was increased to 17ns by the cache, and is now much worse after Microsoft’s new cumulative update. has been applied. In fact, the latency now stands at 31.9 ns, so the problem is not far from twice as bad (and triple the original latency).
There is good news in the report, however, and that is that AMD has given us release dates for fixing these two bugs, according to a post on Reddit.
The L3 cache issue has already been fixed by Microsoft, indeed we have seen references to remedies in development builds of Windows 11 go back a month and the fix is expected to be rolled out on October 19th.
Wait a bit longer for the other issue to be addressed, which is an issue with UEFI CPPC2 affecting some apps and games, but the fix is expected on October 21. Note that these are target dates, so it’s not inconceivable that this will last – tiny issues could arise to delay things a bit longer.
Analysis: A painful problem made worse but don’t rush or rush the solution, Microsoft
It’s an alarming measure to see cache latency increase even more quite dramatically, really after applying a bunch of Windows 11 fixes, and that could obviously leave some AMD CPU owners even more frustrated with their performance. of game.
That said, this is only one test case for a particular Ryzen chip, so we can’t overemphasize it. Other people may not find the same with their PC, and indeed, there are posts on the Reddit thread linked above where gamers say they don’t see any noticeable difference in their performance levels.
The level of impact is, of course, based on a whole host of variables, including not only the exact hardware configuration of the PC, but also the game being played (and the parameters with which it works).
As AMD made clear in its initial admission of the cache latency issue, the most important performance, up to a 15% drop in frame rate, is apparently what it describes as “outliers.” So most systems shouldn’t see this kind of slowness.
Those bigger slowdowns are likely to be for those using CS: GO at 1080p and high frame rates, with a high refresh rate monitor for super smooth gameplay (AMD specifically mentions esports shooters like the worst case scenarios). Of course, these are the kind of competitive players who are going to pull their hair out even with a slight slowdown, not to mention a double-digit drop.
Other people more likely to see their performance levels affected are those running 8-core Ryzen chips or processors with even more cores than that (and TDPs over 65W), as AMD previously has. clarified is the case with UEFI CPPC2 bug.
Tech PowerUp makes an interesting point about the urgency of these fixes, not only because of the potential high levels of slowdown experienced by an apparent minority, but because of the impending launch of the Intels Alder Lake chips.
The new 12th generation Intel processors are expected to arrive in early November and are tuned to work with Windows 11. This means reviewers will rate this operating system and do the same with AMD Ryzen 5000 processors for comparison and contrast. performance. So if the results of Windows 11 with the Ryzen chips are upset by these bugs, it’s easy to see why AMD is so keen on getting the fixes to keep Alder Lake from looking even better than it should (with rumors already indicating its a strong performer).
However, if Microsoft rushes a fix for next week under pressure, well, we can only look at the history of wobbly Windows Cumulative Updates that fixes something while breaking something else, and hopefully that won’t be a scenario. which we will face again later. in October.
