You are the star!
Thanks a lot Karba

- after reopen file, (3ds Max 2011) all emission slots in diffuse material, became empty, and had to reload all textures again,

- all power in Black Body Emission reset to 100

- no chance to make simple UVW mapping when texture is in distribution slot (texture emission) sometimes work sometimes ...

Problem:
I have GTX590 3GB for rendering and GTX 680 4GB for monitor and rendering
when 1 procesor used from gtx590 - shows 1260mb available memory
when 2 procesor used from gtx590 - shows 640mb
when I used all - shows 510mb or less

driver: 310.90

???

fixed
if anyone else have the same problem ...

I bought a 4gb gtx670, on 2.58e failed, and the 2.59 does not see any GPU.

installed every driver from 301.42 to 306.23 all failed (installed only graphic driver and removing every time with sweeper)

WIN7/x64/i7/16RAM/EVGAGTX670 4GB/
