Just tried the alpha 5 with openCL support. But mandelbulber claims the openCL.dll to be missing in the system. Using a nvidia GTX960 with current drivers installed (on win10 64). Can find several opencl.dlls in my system partition. What is going wrong?

Hi Taurus,

can you tell me the exact driver version installed for your card?
Also the location of your OpenCl.dll files would be helpful.

Maybe its an issue with OpenCL.dll vs opencl.dll?

The program expects to find the dll with: const std::wstring openclDll(L"OpenCL.dll");

This problem is related to the NVidia driver. Many users of NVidia cards report this problem. In every case helped reinstalation of the driver to the newest version.

Ok the driver update was successful but the next problem followed instantly. Hitting "render" shows the following. Tried with several settings.

Maybe I was too greedy. The limited setting works and wooah - fast. Here's the screenshot, that didn't work.

So everything is all right. "Fast" engine is not implemented yet.
