I am using 417.35 with 4 Titan RTX and no problems so far.

Maybe Win10 is more stable then Win7 with Octane. I consider upgrading but with all the tools and stuff it would be a nightmare...

Hi mbetke,
upgrading to Windows 10 you will loose 19% VRAM on each GPUs, It doesn't depend on Octane.

I'm sorry, you're right, 417.22 doesn't support Titan RTX.

I'm not maxing out the 24GB at the moment. So 20GB would be okay.
Next year there will no Win7 support anymore and with NVLink I will get more VRam.

So the 20% trap will come sooner or later for all windows 7 users.
I don't think Microsoft will do anything about the VRam reservation anymore. The issue is open for such a long time now and affecting all people using CUDA.

New report from my CUDA999 error.
I sent you scene via PM.

As soon as I disable "Enable Displacement" in Kernel all works fine.
Maybe you find a bug there.

Hi mbetke,
I feel the same about Micosoft..

Hi mbetke,
about CUDA error 999, you should fix setting TDRdelay:

https://msdn.microsoft.com/en-us/librar ... s.85).aspx

In the Standalone installer we set these values:

WriteRegDWORD HKLM "SYSTEM\CurrentControlSet\Control\GraphicsDrivers" TdrLevel 3
WriteRegDWORD HKLM "SYSTEM\CurrentControlSet\Control\GraphicsDrivers" TdrDelay 10jh

Some Win 10 users have set the TdrDelay at 60, to solve their stability issues with Nvidia drivers.

What is "Live View"?

My settings were:
TdrLevel 3
TdrDelay 10

I set TdrDelay to "60" (although I'm using Win7) and kept Level on "3".

Hi mbetke,
sorry, last forget the last two lines.

I tested with new registry settings. It renders without crash but the computer hangs, lags so hard that I only can do one thing every minutes until driver crash.
Only with this scene and displacement.

I will give up on this and built the metal framing with geometry...would appreciate a solution for further versions because it is something wrong in Octane.
