Hey Aoktar: I use both for rendering but the machine does nothing else... so there are no demands on it bar Cinema and Octane...
I'll give it a try especially minimizing the memory used in scene but I'm loath to lose one render card
I'm not positive but when It seems to be rendering a frame slowly- If I minimize and then maximize the picture view it *seems* to kick it back into life? I'm probably imagining it but it does seem to work

I thought there might be something going on with the screensaver or some idle mode my machine is slipping into. That's why they are so spaced apart...?
No idea, will let you know what I find...
Cheers!
