Hi,
I know the version of substance painter I have (1.7.3) is no longer in support; however, I seem to not have an upgrade path available and have been getting this TDR problem on my Quadro K4000.
I previously had the 391.33 Certified driver version, and updated to 397.93 QNF but it didn't make any difference to SP crashing with the TDR error 7.
I have a temporary work around by extending the TdrDelay (0x00000014) and TdrDebugMode (0x00000001) in registry settings (
https://docs.microsoft.com/en-us/windows-hardware/drivers/display/tdr-registry-keys)
I just have never before seen my GPU on this thing go to 100% for over 3 seconds

The TdrDelay is set to 20 seconds now, and after many attempts to extend it I found that the model I had been working on had atleast a 10 second delay loading or whatever it was doing with the textures. There really are not that many honestly (imo), but it is what it is.
I am not expecting any miracles here on a backport if a fix is resolved, but I thought I would contribute here about this anyway. If a fix is provided in a newer version of SP; perhaps a grace upgrade path for us older users could be offered? ;p
Anyway, I attached logs from before and after the driver update.. while I do not believe any specific errors are shown in the logs other than system specifics.. it was clearly the TDR error 7 code (timeouts).
If you all would like the project file, please feel free to contact me and I would be happy to email it or provide a dropbox/onedrive DL link for you.
thanks! (still a great tool)

I added DxDiag as there appeared to be a WER6 notification regarding substance painter with a fault bucket code
