Hey,

I got this really weird bug
https://www.dropbox.com/s/lexq2ov0vxp0m ... 4.log?dl=0

while rendering really simple scene
https://www.dropbox.com/s/dzbhznyb61ux6 ... t.c4d?dl=0

VRAM used/free/max:8Mb/35Mb/6Gb

looks like a weird statistic on VRAM.

Try with 3.02. It's working fine on my laptop with 630M.

It's still occuring afrer installing the 3.02.R2
Here is the log https://www.dropbox.com/s/12i13tw7ilm6a ... w.log?dl=0
and simpel file https://www.dropbox.com/s/u7bw62l4x5vsy ... t.c4d?dl=0

Any help?

Here what i see

VRAM used/free/max:1Mb/33Mb/6Gb

used+free should be at least 4.5 or 5gb. Here is 34Mb. This is very strange and i never seen this before. Here is what i see on my test render. Note that the red areas. I think there is some problem on your GPUS. But i'm not sure. Can you try on standalone. Let's see the gpu stats.

Here is the octane standalone result

stats are a bit weird really, I think something got messed up after I installed Nvidia drivers :/

Any ideas?

Hi samborek,
do you have only the GTX 980 ti on your Mac?
If yes, how many displays have you connected to it?
I have CUDA 7.5.26 installed here, did you mean 7.5.29?
Here is the list of the CUDA Mac installers:

Hey,

Only 980Ti here 1 screen not even 4k
I have 7.5.29
But I did notice that Photoshop and damn Chrome are eating a lot of Vram but still I could get it up to almost 3Gb Max if I turn everything off, is that normal?

Edit: ok not sure what going on as it went back to hardly around 2Gb

Hi samborek,
having a dedicated (even weak) GPU for display only is always the best with Octane, anyway, have you tried to go back to 7.5.26?
