GPU error message

I'm running SP on Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz 3.60 GHz, 16GB RAM, NVidia M2000, Win10 Pro. I adjusted TDR in my registry editor, and followed all the other suggestions at https://substance3d.adobe.com/documentation/spdoc/substance-3d-painter-doesn-t-start-on-the-right-gpu-182266570.html.

I'm still getting the GPU error message when I launch SP. 

This is the log:

[Resources List Model] Icons memory budget set to 100MB.
[Plugin - resources-updater] No project open, resources updater discarded
[GPUIssuesCheck] Your operating system may automatically shut down Substance 3D Painter during long computations because your GPU doesn't support preemption.
To avoid crashes, you can try increasing the TDR (timeout detection and recovery) delay
(Learn more: https://www.adobe.com/go/painter-gpu-drivers-tdr-crash-long-comp).

I don't know where to set Icons memory budget - my local cache budget, in preferences, is set to 3000MB.  Suggestions? Ignore the error message? I'm not actually crashing but a 220MB file is stuttering occasionally and slow.
