HC3 not working, vs HC2

Hi,

I previously used HC2and it seemed to work well.

I use x11-drivers/nvidia-drivers-367.35 on my system


cudaHashcat-2.01 # ./cudaHashcat32.bin -b
cudaHashcat v2.01 starting in benchmark-mode...

Device #1: GeForce GTX 560 Ti, 963MB, 1670Mhz, 8MCU

Hashtype: MD4
Workload: 1024 loops, 256 accel

after downloading the HC3 binary, it seems no able to find the cuda device?

hashcat-3.00 # ./hashcat32.bin -b
hashcat (v3.00-1-g67a8d97) starting in benchmark-mode...



ERROR: clGetDeviceIDs() : -1 : CL_DEVICE_NOT_FOUND


Do you have any advice how I can fix this? Do I need additional binaries installed? I did not find a seperate cudahashcat and oclhashcat 3.01 so i guess it is included?
