i installed the latest demo version along with cuda 3.0 drivers. cant seem to render out some old scenes i tried with previous demo 8.1a. it just stalls when i click on the mesh node. it renders the old demo scenes provided like the chess scene and rocket scene... the old scenes which wouldnt work were imported out of Sketchup.
maybe i gotta install cuda 3.0 drivers again... how can i uninstall it????
PS.. i tried rendering the same scene with 8.1a demo again and it seems fine...
any help would be most helpful.. seriously considering a buy here this week.. but without it working....
