I did- I did a clean re-installation of Windows and it completely resolved the video playback issue, and also fixed a whole host of other power management problems I was also experiencing (e.g. battery drain when in sleep, processors over active, etc.). Pretty annoying to need to do that out of the box just to have a functional laptop, but everythign runs very smoothly now. Hope this helps.
Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.
I had problems with video performance when trying to use my laptop (Dell XPS 15 9500, GTX 1650 Ti, 16 GB RAM, 1TB SSD) with Steam VR. After some time using my headset (Oculus Quest 2), the performance would become unworkable. Then after some time it would get back to normal and after some minutes again go down.
I spent several hours to resolve this, and I am writing this up in hope it may save someone time and frustration.
My problem was that Steam VR, after starting, set the power plan of the laptop to "High Performance" (a setting not available when Steam VR is now running - maybe it creates a power plan and activates it - people are complaining about that in forums).
This power plan made throttling of the laptop behave irregularly: Despite the temperatures of GPU, CPU, Hotspot (as shown by GPU-Z) were fairly low, "PerfCap" (performance cap) was kicking in as a combination of excess power being drawn (Reason: "Pwr") and excess temperatures existing (Reason: "Thrm"). When throttling for either reason the laptop runs OK. But when it throttles for both reasons ("Pwr,Thrm") then it drops the memory clock to 300MHz and performance suffers greatly.
What I figured is that it stays in that clocked-down state for a given amount of time, before stops throttling. This period is not defined directly by temperatures nor power drain. Can not be less than some minutes no matter what. Can be more than some minutes though if the load remains very high.
SOLUTION: You can either restrict your application from changing power plans and lock your laptop in one power plan ("Dell" power plan works fine with me), as described here:
If downloaded videos play reasonably well, but streamed ones do not, the network connection is all but certainly the cause. If you have more than one device connected and they're OK:
1. Dump McAfee if it's running and use Windows Defender
Check out my "solution" post from February 2021- for me the solution was to do a clean install of Windows. That solved all my video playback issues and performance issues. I highly recommend starting there before purchasing additional hardware/software/services.
I just bought an XPS 15 9510 and I have the same issue. At first I thought it my be because I was using an external monitor, but on removing that, the problem still exists. I've ordered a memory upgrade, and I'll see if that makes any difference. I've run the Dell and the Norton system diagnostics, and nothing comes up. Any assistance would be greatly appreciated.
Hmm, I've done two clean re-installs since getting mine in... I had the blue screen of death many times and the same issues as above. I guess it's due for another clean install for the third time! ridiculous.
I have the same issue with my dell xps 9700. Youtube lags especially when my laptop is not plugged in. Sometimes screen goes black then comes back and windows animations lag a bit also. I noticed that after disconnecting my charger a certain time processor gets stuck at 0.78 Ghz. I reinstalled windows 11, went back to windows 10 with full disk clean but the problem persisted. Really disappointed after paying 2700€ for my this laptop that I like too much but with this problem it became unusable at all.

Did you find a solution to this? My Dell XPS 9500 has the same issue.

Dear Dell moderator,
Is there a solution available I seem to have the same issue on my dell XPS 15 9500?
Kind regards

Specify a custom active Power Plan and force Windows 10 to use it (thewindowsclub.com)
OR, have the control panel open and when the power plan switches to whatever exotic plan the app prefers, switch it back to "Dell" or "Balanced"
Hope this works for you!

1. Dump McAfee if it's running and use Windows Defender
2. If you're running SmartByte, disable it:

I have the same issue. I tried to do a fresh install AND the tool says my version or language of Windows 10 is not supported by the tool.
I'm on a brand new Dell XPS 15 9510.

Uninstalling Nvidia graphics card driver and reinstalling it solved the program

The solution for mine was to do a wipe and clean re-installation of Windows. Haven't had the issue since.
