Author Topic: Substance Painter cannot access Graphics Hardware.  (Read 5240 times)

As soon as I load my project, it says that Substance Painter cannot access the Graphics Hardware. I'm on Windows 10 and I downgraded my gpu driver to 347.88, nothing works for me. I even changed the TdrDelay to 8 seconds and my system still crashes.

Anything I can do? :)

Don't forget your log file. It can be exported from the Help menu of the software.

Thanks, can you also give me the exact error message that you get ?

Well there's an NVIDA OpenGL error message that says:
A TDR has been detected. The Application must close

Error code: 7
Would you like to visit

There's also another message that pops up saying:

Application has been blocked from accessing Graphics hardware. Application Substance Pain has been blocked from accessing Graphics hardware.

Looks like it's still a TDR, I suppose you already saw these pages ?

Try increasing your TDR values, mine is way higher than 8 seconds.

Ah okay, would you recommend like 60 seconds?

Yeah it still comes up with the same error message. The thing is, I set it to 40 seconds and it only last like 5 seconds before the message pops up. The first and second sentence of it (A TDR has been detected. The application must close.) suggests that I shouldn't have a TDR in the first place.

There is more than one regedit key to edit to avoid the TDR error message. I suggest reading again the webpage of the Microsoft website.

Alright well I'm not exactly sure which other Tdr to add as I'm not very experienced with this. So can you tell me which one specifically to edit?
