Please update bad advice in documentation
In https://docs.substance3d.com/spdoc/gpu-drivers-crash-with-long-computations-128745489.html, one of the suggestions is "Disabling the TDR completely -> Set "TdrLevel" to 0 ( not recommended )". Even if it says "not recommended" this suggestion cannot be safely done in a PC running DX12 applications. For DX11 application TdeLevel=0 effectively is the same as an infinite timeout, however with DX12 you also get page faults which go through the TDR handling mechanism. When these are triggered, it will cause an unrecoverable PC hang. A number of substance painter users in our production had followed this advice and it took us a number of weeks to track the source of the issue down.
Thanks for reporting (and apologies). It's now fixed.
