GPU Drivers crashing

[marchermitte]

Hello
I'm getting an error code 3 with my drivers while using the preview. (message says that "drivers stopped responding" (French Win7)) and lightwave crashes. The strange thing, everything worked well before I re-sized the ground plane and beveled the further lower edge to get some sort of a studio background.(might be a coincidence)

Any Idea?

Thank you!

Do you have displacement mapping in your scene?

If you want to send to me the scene I could test it here.

Yes I do. Only at 1024, nothing crazy (just adding some displ to a mdd driven mesh)

Try to use a lower displacement amount to see what happens.

Do you have the Standalone installed in your system? ... I think that Standalone install program changes one system variable to make the drivers more stable.

I have the original Standalone 2.06 but I haven't updated it as I only use the plugin. Do you think I should update the standalone? I still have similar problems (we've discussed this in other threads) so could that make it more stable? Or do you know what the installer changes so I could check if I already have those changes?

Try this, You can manually change the settings to get a higher timeout via the registry editor:
- Launch the regedit (Start -> Run window -> regedit)
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
- The key "TdrLevel" should be set to 3.
- The key "TdrDelay" is the delay in seconds. Maybe set it to 20 or 30.

Restart your system and try again.

Fast answer
Thank you, I'll try what you advised and let you know how It goes.
For now I'm rendering without the displacement.

Great
Level was 3 but delay only 10, now it is 30.

Let's hope this helps

Can this also affect the 99% render stuck problem? The driver does not SEEM to crash at that point but could it still be related?

Thank you very much again!

I have a scene where GPUs keep crashing and then recovering back every minute or so. Tdr level and timeouts are fine. It isn't related to the timeout since once I put it to 60 seconds but I could see Octane is having trouble becuase the buttons on the rendering progress window would freeze, then after approx. 60 seconds I would get a GPU crash/recovery notification. It is just with this one scene and I was not able to isolate the problem. Should I send this scene to you Juanjo ? In LW or standalone version ?

It is a heavy foliage scene, I had similar troubles before but I corrected it by upping the timeout. This time this doesn't work.

If you can reproduce the problem in Standalone it is better to know if the problem is in Octane, but I only have 3 GB of GPU RAM, I am not sure if I am going to be able to test your scene here if it is too big.

Usually this problems are related to the displacement mapping. Try to use less resolution for the maps, or less displacement distance. Also very dense FFX hair systems, or hairs too thick can crash the drivers. And of course, what perhaps is the problem of your scene, too complex shaders with transparent or opacity layers ... you could try to change the kernel, or use lower ray recursion.
