Hi Sylvain, Nice work, I just gave it a spin here are my results;- I hit the 'clCreateFromGLTexture' issue when compiling the benchmark tool, not only did I need to comment out the #define but I also needed to turn off -Werror in the makefile. I get 61msps with a GT9800 on a i7-950 @ 3.06G Inter

[Discuss-gnuradio] First proper build - missing blocks
