There is a strange article about OTOY on a website called venturebeat.com .... HERE LINK.
Sounds a bit wired in my ears, bud this claims, Otoy have reverseengeniered CUDA and can run it on any GPU´s in the near Future. Means that for example OCTANE can run native on ATI GPU´s ,too.
For me, as MAC PRO 6.1 guy, waiting since nearly a year at the promised octane 3.0 openCL support it sounds a bit unreal, but interesting..... let´s see , what happens =)
