Hello, I have an MSI GeForce GTX 980TI 6GB video card. I updated soon as the NVidia 378.49 driver came out. I went to CloneBD settings and for hardware acceleration my CUDA was greyed out. I never had this problem before. I did some tests from the CloneBD hardware acceleration sticky forum troubleshooting, and the results are posted in the log file. So I rolled back drivers to the second newest NVidia driver in Device Manager ,and POOF CUDA is checkable to use for hardware acceleration in CloneBD again. I'm sure Elby, has to just update driver support for CloneBD for NVidia CUDA to the newest driver version.
