Quote - that's one thing.. does the collect textures speed up rendering? i've always had it checked because it seemed like the thing to do.

With GPU rendering, its pretty much manadatory. The idea is that all the texture maps are being collected into one huge map, kinda like Texture Atlas if you've used that. Textures, rather, than geometry, is what sucks up all the memory in a render. To get an idea, watch the log when you call Lux and see how many textures are loaded. Then multiply by the average 2k texture (most human characters have 27 maps, ranging from .5 to 4k for reference). That's why its about the only way to get 2gb of video ram to process a larger scene. 

The one I've got running now is 5.7gb at full size, CPU only, and nine additional light channels. Just got the driver dl'ed, so maybe I'll get a test frame done later tonight. Time to go for the nightly father-daughter visit!
