Hi,
just started to try some hardware render engines for testing. Now I had to realize that I have no idea what’s happening on the graphics card. I have a GeForce GTX 560 with 4GB ram. But all hardware engines, Viewport 2.0, Redshift, Octane, only see 1.2 GB ram. In the nvidia system info I can see taht I have 1280 MB dedicated video ram. So my question is: If I can use only this dedicated video ram, what are the other 2.8GB ram for? Are they used at all? Is this different on quadro cards?

That is really strange. I’m using a GTX 550Ti, different card but it’s only got 1GB on it, and all 1,024MB show up in the Nvidia System Info, as well as in Maya/VP2. Let’s not just jump to conclusions, but it’s possible your card doesn’t have 4GB on it, after all?
I also use a GTX 660, a newer card, which only has 3GB on it. Perhaps you were sold the wrong model?
Here’s the spec sheet for the 560, straight from Nvidia. Default was only 1GB of RAM, not 4GB, although of course some vendors would add more. I’m not sure it COULD support 4GB though.

The interesting point here is that in the nvidia system info I can read:
Total available graphics memory: 4096 MB
Dedicated Video Memory: 1280 MB GDDR5
So I suppose there are 4Gig on the card, but not available for normal render tools.
