Cycles CUDA driver etc.

Hello Everyone,

The more I search, the more confused I get. Please help clear a few things up
I have an NVIDIA Geoforce 8800 GT - CUDA 1.1 - running Ubuntu 12.04 32 bit.

From what I gather, a driver upgrade does not change CUDA compatabilty - correct?

I see that there are some builds on GraphicAll that work with lower CUDA (unfortunately for me, they are 64 bit).

Does this mean that I could build Blender myself, and make certain changes to the source files that would allow CUDA 1.1 to work?

Thanks in advance

Correct

All you (theoretically) have to do is edit a build flag, but in your case it almost definitely wouldn’t be worth it. Cycles will not render some effects in cuda compute capabilities lower than 1.3, and since your card is so old the CPU would probably be faster anyway.

JamesNZ,

Thanks for the info - I’ll have to wait until I can aford a new video card.
