Microstuttering when running on external monitor

Hi guys,

 

i noticed that I had stuttering when doing stuff (even just moving the task manager around) on the external monitor.

Searching for a solution I found this reddit thread: https://www.reddit.com/r/eGPU/comments/djivwi/micro_stuttering_fix_for_lenovo_yoga_c930_with/f4dxe6r/

The proposed solution actually works. Disabling and reenabling the iGPU in the device manager fixes the issue.

Running extended mode instead of just the external monitor helps a bit but is not as good as the other solution.

Despite the title of the reddit thread it seems like the issue affects all kinds of laptops.

 

Now my question is: I did not come across this issue here as far as I am aware but from my experience and the reddit thread it seems to be quite common.

Does someone here now about a good solution?

Are some drivers messed up and reinstalling could help?

If not then is there some script that can automate the dis-/reenabling of the iGPU when the eGPU is connected?

 

Kind regards,
Christian

I just wanted to chime in because I have the exact same problem: Dell Precision 5540 Laptop (with an Intel 630 iGPU and an Nvidia Quadro T2000 dGPU) > Razer Core X with an AMD 5700 XT and my two monitors are connected to the AMD / eGPU card and I do get microstutters no matter what I try...

 

I tried

  • All GPUs enabled > microstuttering happens
  • The two iGPU/dGPU disabled and only eGPU enabled > microstuttering happens
  • re-enabling and re-disabling iGPU/dGPU after bootup > microstuttering happens
  • I tried thermal pasting the CPU and iGPU/dGPU to improve thermals / take thermal throttling out of the picture just to be sure (and also use ThrottleStop) > microstuttering happens

I typically have my eGPU connected all the time, so not plugging it in 'plug and play' while the system is running, but I think I remember having the microstutter problems in that scenario, too. I also run the laptop with its lid closed (and therefore its display off) and the two external displays are run as 'Extended' in Windows' display settings.

Moreover, when this stuttering appears it is not only visual, just like this user reported on the dell forums, if it happens in the exact moment I am typing / pressing a key.. it appears that that key gets stuck and the input contuinessssssssssssss.... even though I let go of that key already.

 

At the moment I am somewhat lost what else to do. I am running Windows 10 2004 and all drivers are up to date. I have no Error-12 or so problems and it's quite unfortunate to hear that it seemingly affects all devices.. or well.. that's what I'd like to hear/know, too: does anybody with monitors connected to their eGPU NOT have microstutter problem and if so, did it just work or what were the fixes/steps necessary to get there?

 

Thanks,

-J

One update here: I tried 'one last thing' (hopefully) which seems to finally have fixed the problem for me: as mentioned before I had the laptop lid closed all the time and only used the external displays hooked up directly to the eGPU.

However, I just gave it a try to keep my laptop's lid open AND use them along with my external displays - those still being attached to the eGPU - and none of the iGPU/dGPU is disabled. All three displays are set to 'extended' and it works! By "works" I mean: I haven't had one microstutter in the past hour.

 

Will keep this post updated if this does fix this indeed.

Nope, does not fix it.. just make it much more less common / occur less. However it happened in a 'burst' again.. meaning it happend 4-5x times within 1-2 minutes and now it has not happened for a while again.

I appreciate you writing this out very much. I have an x1 Carbon Extreme, gen3, so I was forced to have an iGpu, a dedicated gtx1650Ti, and now an 2070 Super eGpu.
The same issues with microstutter, also fixed by keeping the lid open. Can not yet confirm that they "return" after a while.
