Using Cuda 10.2 after OpenCL installed
* Device #1: GeForce GTX 1080, 8118 MB, 20MCU

OpenCL API (OpenCL 1.2 pocl 1.1 None+Asserts, LLVM 6.0.0, SPIR, SLEEF, DISTRO, POCL_DEBUG) - Platform #1 [The pocl project]
* Device #2: pthread-Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz, skipped

OpenCL API (OpenCL 1.2 CUDA 10.2.120) - Platform #2 [NVIDIA Corporation]
* Device #3: GeForce GTX 1080, skipped

From what I've been reading Hashcat would perform better using the 3rd option(which is skipped). I've read over the help files, but I can't find anything directly addressing this issue. I'm not sure if I need to uninstall the CUDA 10.2 or if I can somehow just tell hashcat to use the OpenCL 1.2 Cuda. It has been a long road to get to this point, and I will really appreciate some help.
you can select individual devices using -d

but as can be seen hashcat will use device #1 by default, which is the CUDA interface of your GPU, which is optimal.
Thank you so much!
