hi bill, yes, i thought so. but the gpu lux is command line tool that comes without readme, unless i missed it of course. thought it would be plugable into the luxrender.exe, but didnt find out how yet. it is searching for a kind of configuration file that the luxrender does not need.

i have tried the octane demo, and now that i saw it i cannot wait 10 hours for a render any more. i need gpu. like air to breath :)
