In early October, Microsoft publicly released the 22H2 update for Windows 11. This update brought several new features to the operating system, the return of several features common to Windows that were common in older versions, and several bug fixes. Unfortunately for those that play video games, which is probably you if you're reading this, it also introduced several performance issues.
First off, Nvidia owners that performance in games was severely degraded following the update. Framerates were way down, there was apparently lag, and users' CPUs were being woefully underutilized. Nvidia discovered the issue and first issued a beta update for the GeForce Experience that addressed the issue. This update was then rolled out to the public, so if you're on GeForce Experience 3.26.x you should have the fix already.
The problems do not end there. While Nvidia has done what they could on their end, there are still issues for PC gamers. These issues are not limited to those with Nvidia hardware either as it impacts hardware configurations from all vendors. Microsoft lists "lower than expected performance in some games" at the top of their known issues list for Windows 11 22H2.
Microsoft says that there is a software bug in the 22H2 update that causes games and apps relying on the GPU to trigger a developer debug feature. This debug feature was obviously never meant to be used, seen, or accessed by consumers. It's this debug feature that is causing the performance degradation for end users that updated to 22H2.
Due to this issue, Microsoft has temporarily halted the continued roll out of Windows 11 22H2. If you have not yet updated to 22H2 yet, it will not be pushed to you via Windows Update until Microsoft is confident the issue is resolved. Microsoft also warns against using the Media Creation Tool or the Update Now button in Windows Update to bypass this Windows Update safeguard.
If you have already updated to Windows 11 22H2, Microsoft suggests ensuring your games and other apps are up to date. Frankly speaking, this sounds like a really dumb solution given that the issue seems to originate from within the operating system itself. If it's still possible for you to roll back to a prior version of Windows 11, that would be even better. The best course of action would be to just go back to Windows 10 if that's an option for you. Windows 11 in general still needs a while longer in the oven.
Microsoft says that they are "working on a resolution and will provide an update in an upcoming release." A release date for this potential fix was not provided by Microsoft.
As for reasons to move to 11 from 10? I guess it depends what you want. Explorer in 11 has tabs now, but they're half baked. Apparently DirectStorage will also work better in 11 compared to 10 somehow. There's that snap layout thing, but I think you can basically get the same thing with PowerToys' Fancy Zones in 10. Uhhh... Windows now remembers what monitor apps were on when your computer goes to sleep instead of them all moving to one monitor as is common with 10. Apparently there's better touch/pen support in 11.
But like, that's kind of it? They still have so much crap in 11 that is just half finished. It's mostly 10 with a coat of paint but they missed painting so much legacy stuff still.
I've been looking for a compelling reason to move to 11 from 10 for a while now. I thought explorer tabs would be it but then I hear about how poorly it's been implemented and how it's lacking features that browsers have and I'm just like "mehhh." They still force you to have that "Recommended" section of the Start menu for no damn reason. Then there are these performance issues that seem to pop up more and more with 11.
