Hopefully the video cards mean something to some people. I have a Radeon HD 5770 and it is just fine - I have no idea if it is new/older better/worse than yours.

I would suggest verifying without hardware preview, i.e. SreeD. If editing in the mat room is no longer laggy, then there is some unfortunate interaction with the video driver/hardware.

Now - just to be clear, if I have a material with 8 or more of those noise nodes (fBm, Noise, FractalSum, etc.) then it is laggy as all hell in updating. That's just because the tech to do the preview is probably lame.

All that stuff was developed long ago and bought for Poser 5. I don't think it has had an overhaul, ever.

I will say it again and everybody should repeat - I have 8 CPU arithmetic cores. Any program that only uses 1, like it's 1999, is soon (6 years or less) going to be removed from my computer - period. When I have 64 cores, anything that can't use them will be in the trash.

I already have hundreds of processers in my cheap graphics card, capable of 520 GFLOPS. If, in 6 or so years, I am sporting several thousand processers and can do 8 TFLOPS and the software I use is stuck using about 1/100th of that, it's going in the trash.

I expect real-time material preview, including reflections, in 5 years. SM?
