[Bf-cycles] cycles standalone strange rendering...or code / build bug?

[Stefan Werner]

Cuda-binaries instructs the build to compile the CUDA binaries with the rest of cycles, as opposed to doing it on-demand at runtime. I'm not sure if the latter works on Windows at the moment.

CUDA-dynload tells it to use CUEW instead of the CUDA SDK directly. Doing so allows the resulting binaries to run reliably on systems without CUDA drivers.

For builds that you intend to distribute to others, I recommend to turn on both options. For development and debugging, turning both off will shorten build times and make it more compatible with nvidia's profiling and debugging tools (which in my experience are  it reliable with CUEW).
