There is no *.cubin files generated.<br>I read the svn log r41657 and find that cuda binaries will be generated at runtime.<br>Then I launch blender.exe and set cycles device to "GPU".<br>Then,in 3D View window, I set ViewportShading to Rendered, but nothing is rendered. <br>The blender console window says:<br>`C:\Program` is not recognized as an internal or external command, operable program or batch file<br><br>I infer that Blender uses some CUDA environment variable which contains a whitsapce character.<br>Then I set environment variable %CUDA_BIN_PATH% from %CUDA_PATH%\bin to "%CUDA_PATH%\bin", and relaunch blender,<br>I find that it is "OpenCL GPU" instead "GPU" in Property->Render->Device. It means I can't use CUDA anymore. Very
strange!<br>I load factory settings and delete all *.pyc in BlenderROOT\2.60\*, and relaunch blender, it is still "OpenCL GPU". <br>I want to use Cycles with CUDA, but where is the "GPU" gone?<br><br>My environment is WIn7-x32, and some environment variables are:<br>CUDA_BIN_PATH=%CUDA_PATH%\bin<br>CUDA_INC_PATH=%CUDA_PATH%\include<br>CUDA_LIB_PATH=%CUDA_PATH%\lib\Win32<br>CUDA_PATH=%CUDA_PATH_V3_2%<br>CUDA_PATH_V3_2=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\<br>PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v3.2\bin\;C:\Program Fil<br>es\NVIDIA Corporation\PhysX\Common;.;C:\Program Files\Novint\HDAL_SDK_2.0.0\bin;<br>D:\ProgramFiles\Perl\site\bin;D:\ProgramFiles\Perl\bin;D:\Program
