GPU Render Issue

[rdcontent]

Hi guys

We're having a problem here whereby when starting a render out from Cinema 4D with Octane the frames start off fine - rendering for example at around 1 minute each. After about 50 frames roughly the speed starts to decline by about 10 seconds each and eventually one of the GPU's stops being used to render. Has anyone else encountered this error? If so how did you go about fixing it? My only work around is to stop the render and restart it again from that frame to get back up to speed.

We are using 2 x GTX1080TI's.

Thanks in advance.

Please post some information about your rendering.
Open console and find output about render log for whole frames

Hi Aoktar.

This is what I found in the Octane log (Have I missed something? Is there a seperate render log?):

Also attaching some screenshots -

Here is the GPU at the start of a render:

Thanks again!

I have restarted the computer, reopened the project and begun the export again - this time also including one network render slave and it is now continuing at the same speed without dropping or losing a GPU. Could this be a bug?
