OCTANE RUNS SLOW

[manos]

Hello im working on this small project... i notice after adding more geometry in to my scene, octane starts to work very slowlly...
i restarted computer and it got better
is this sounds normal ? i dont know much about the new ver of octane that uses some of the computers resourses...can anyone advice - help ?

Hi manos,
there is something weird, looking at your screenshot, it seems that you have another CUDA application running and you are loosing VRAM and power, I guess
You also have alot of movable objects, but no animation... why don't you work with one single obj node?
which is exactly your workflow?

Well, I'm using the sketchup plugin for exporting the scene and when I need to add geometry I hide everything alse and export again ....if a geometry is complex I prefer to use the plugin export but I also use the sketchup a obj exporter for less complex geometry....

2gb card is the reason i think. You are running out of GPU memory. Can you invest in 8 GB 1070?

Hi manos,
2GB of VRAM are not too much, but there is another issue here.
As I told you in the previous message, you are losing too much VRAM, 800MB on a 2GB card is too much:

Since you have 4 GPU, could you try to disable the GPU connected at the monitor?
Which GPU do you have exactly?
Do you have the MultiGPU active or SLI enabled in the Nvidia control panel?

I have two GTX 690 with 2gb ....

Sorry I ment two GTX 960

beppe is right - use one gpu (not graphics card but a gpu chip) for monitors.

To do it so you have to disable so called internal sli bridge on 690 in nvidia settings - I did it some time ago with Titan Z. So you'll have 3x680-like gpus for rendering with fully available 2GB of vram.

Cheers.

... but my best recommendation - sell your 2x690 - they are power hungry - and get 2x1070...or even 1060 with 6GB of vram - you'll love them and your energy bills will go down drastically

[smicha]

...sell your 960 then .... or keep it for monitors and add 1060 6GB for rendering.
