Subject: Re: Nvidia CUDA drivers

Hello,

My bad, did not knew that Nvida supported OpenCL .... JtR Its now running
with OpenCL.
Anyway, just saw these graphic cards are almost useless but wanted to
report that some of the OpenCL formats fail to run in case its relevant for
someone - please see below.

Thx
Luis
