Pascal and Maxwell on the same computer?

[mbutler2]

Anyone using Pascal and Maxwell GPUs on the same computer?

Wondering if there are any driver issues or Octane issues?

I'm on Windows 10, looking at adding a 1080 to some 980 TI's.

Running 780gtx(Kepler), 980ti(Maxwell) and Titan X(Pascal) as of a few days ago. All working fine through Octane C4D Plugin.

I did have to update my bios to the most recent available. I was having issues with the 980ti and especially the Titan X Pascal before the bios update.

You are running the history of GPU's, rafg! Sounds like a nice setup.

What's your OS, Win 10? What's your motherboard?

How much faster is the titan x pascal compared to the 980 ti ?

Please post results of speed for Pascal X and 980 ti on the same scene on various kernels - DL, PT, PMC. Always use the same settings and same scene camera for comparisons. Thanks in advance.

Yes please !

Also is there a difference in scene loading time compared to other cards ?

Will do at some point today or tomorrow if I can.

This is not scientific by the way. Just opened up the Octane benchmark file I had and set it randomly to Time: 3/15/2013, 02:13:52. It was not updating every second so could not get exact comparisons.

So hard to read this data - could you post just speed ms/s info when rendering the same scene?
