    v29 v30  
    88* we have a '''big''' problem with parallel encoding (maybe I just tested wrong previously?): the threaded, parallel encoding tests using 10 threads show that we are quickly reaching the context limit (Tested with both the GTX 760 and 750 Ti, the latter is a bit faster as per above - only tested with drivers 340.x and 343.x):
    99 * at 1080p: sequential encoding goes at about 128MPixels/s, with 10 threads the speed drops to a 15MPixels/s. This only gives us  8fps, which is just not good enough! (the 750 Ti does 12 fps for 10 contexts)
    10  * at 720p: from 128MPixels/s down to 9MPixels/s with the 760 OC, and 184 down to 20 with the 750 Ti. That's ~11fps and 20 fps respectively.
