Screen goes black when switching layers

Jakub

Hello, 

I am experiencing a weird issue while using SP.

I am working on a file with 2k textures, around 17layers total. Substance is working really smooth, no lags, issues, I could probably stack up more of them there. 

When I start switch layers below on&off to check how things look,  my screens go black(or some other color) and I have to reboot my PC. At first I thought it might be my GPU, but I run a lot of stress test, painted 16,000 x 16,000 textures in Mari and it worked fine. Only substance does it. 

Any idea what that issue might be related to ? 

16GB RAM / GeForce 970 / I7 CPU / SSD

Greetings,
Jakub

For a note: I increased the TDRDelay



It still just randomly crashed my drivers. 

I tried stressing out SP by changing between 4k/2k, throwing patricles and rotating light while it computes and it did not crash. But I guess it will tmr, when I'll just try to check one layer Quite annoying

You can't really compare Mari and Substance Painter since our software don't work the same way. Substance Painter work very intensively on the GPU, which can lead to TDR in some cases.

Did you already saw this page ? https://support.allegorithmic.com/documentation/display/SPDOC/GPU+drivers+crash+with+long+computations

Ah yeah, I've already done it. But I also read that it might be the issue with 970 and VRAM, since there is no way to fix it, you can close the topic

The TDR has nothing to do with the memory issue on the GTX 970 however. 
Try to disable completely the TDR in the registry to see if it helps, and if not let us know and we will investigate.

I had my TDRlevel set to 0 since I started using Substance. You can see that in the screen in second post. I added two lines with 120decimal and it still happened after that. 

With VRAM I meant your last post in this topic:

I noticed that crashes are not likely to happen if I start my Substance Painter first, so this is a small solution.
