I have an application that is using OptiX 2.5.1 under windows 7 64bit using Cuda 4.0. It runs smoothly on a machine with a gtx 580 gpu. Now, I switched to a new machine with a gt 640 and I get the following error message:
“_rtContextLaunch2D” caught C++ standard exception:
invalid device function
Does anybody have an idea where this error is trying to point me to.
