How do I test to ensure my eGPU is working?

So I have had nothing but issues with with my eGPU. I have Windows 11 with a Nvidia GTX 1080, using a 7290 2in1 machine. The reason I don't think it is working is because I will be scrolling a web site and the scroll just stutters and pauses, when I highlight text it slows down and stutters the highlighting which makes me think that the eGPU is not being used properly. The Windows 11 device manager says it's there and the drivers are installed properly. I have NVidias Power Management set to Max Performance. 

 

I just want to know if there is a simple test you can do to test that your card is performing as expected. I can do all the benchmarks in the world but it really does not tell me much other then where I rate with other users with the same kind of setup. Also the eGPU seems to work one day then not work another day, once day I can feel how snappy the system is and the next day it seems like opening a window causes slow downs and typing the text stutters and is slower to show up.

 

I want a way for sure way to test to ensure the eGPU is being used. even with the internal GPU disabled Windows can still use it. Any recommendations?

I did find an open source tool called LuxMark and I did a bunch of base line benchmarks. Problem is I don't know if my eGPU is working properly so there is no way to know these are baseline tests. I did look at the site and other results and there is only one other person with a GTX 1080 that was a bit faster then I was on the score. So I guess i have to wait for a time when I think the device is not performing and run the bench mark again?

The stuttering during website scrolling sounds like classic eGPU / iGPU conflict behaviour. Have you tried disabling your iGPU? You might be able to disable and re-enable it immediately and still fix the stuttering.

3DMark has a database searchable by CPU / GPU combination. If you were able to run the TimeSpy Benchmark, you could cross reference your results with the database. There are currently 100 benchmarks with an NVIDIA GeForce GTX 1080 and Intel Core i7-8650U Processor.

Another way to see what GPU is being utilised is to simply open Task Manager, and under the Performance Tab it should list all available GPU's. When you are running a program that requires graphics processing, the GPU that is doing the work should display utilisation percentage load.

I had the same question Thanks for the answer. Smile

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Is there anything that is a stand alone benchmark, these seems to require Steam which I can install if required but would rather a stand alone app that you run that doe not install stuff

Unigine Heaven is a solid graphics test that isn't impacted by CPU performance too much, but doesn't have the same database as 3DMark does.

There are a fair few Unigine Heaven results posted here though, so if you found a system with similar specifications you could compare them or ask the author to run the test themselves. I have a GTX 1080 and could provide you with my results, for example.

That's would be awesome, any way you could also do the LuxMarK with the GTX 1080 and provide your results? Seems like a simple stand alone test. You don't have to make an account you can just write your test down but would be nice to have more results in their database. Here are my results from the test you suggested

Well it looks like the results are pretty close, I am assuming your Unigine one is better because of your CPU, the other one seems to GPU only and you can ignore the CPU. Look sliek I have a reliable baseline. If I notice any slow downs I have something to compare it to!

For giggles I decided to benchmark my iGPU and I have a docking station plugged in at work as well. It blows my mind how well a GTX 1080 card still works!
