CPU much slower on win 11

[Origami Cactus]

So what the title says. On win 10 my laptop could render videos at 3.5ghz on Ryzen 4750u, but on windows 11 it is only 2.34ghz, way slower, it isn't thermally bound.

 

The power slider is gone too, so it seems that my laptop is stuck on balanced powerplan, with no way to get it to high performance.

 

In lenovo vantage the power modes are missing too, so im completely at a loss here, on how to regain my lost gigahertzes.

If you click the thing with the wifi, battery etc and then the battery it will bring you to a settings page where you can change power plan.

 

Also know that there's a cache bug for Ryzen CPU's causing slow downs, it should be fixed soon.

Both AMD and Microsoft put out fixes for the AMD bug... get both

My PC lags a very little bit on Windows 11. Ran perfect on Windows 10. 

 

Well, I guess it could be that this is my PC...

• Make sure you have the latest version of Windows 11
• Install latest AMD chipset drivers for Windows 11
• Install the latest UEFI (reports of some boards has performance issues when fTPM is enabled.. not all boards, some. Nothing officially confirmed, based on user feedback that I read... that said, regardless, it's good to have the latest version, especially when a new OS is released)

Yeah i have the cache slowdown bug probably fixed, but surely that has nothing to do with the GHz i am loosing?

 

I've heard that AMD lost performance per clock with win 11, but i am also loosing just the clockspeed as well.

I don't have an amd machine running 11 yet but windows is stepping down the speed when not under load to save on power consumption. When you do a single or multi thread test like in cinebench you should see it come back up to where it should be.
