Hi Michael, I think a certain amount of slowness could be explained by the limitations of the card. In general, there often won't be a simple linear relationship between the performance on different cards with Nuke nodes, and when you get close to the limits of your hardware you might see performance suddenly drop off in some cases. In addition, the K600 and 600 are very low spec cards, even compared to the K1200, and especially when compared against workstation cards such as the K5000 and M6000:
Model | Cores | Mem bandwidth 600 | 96 | 25.6 GB/s K600 | 192 | 28.5 GB/s K1200 | 512 | 80.0 GB/s K5000 | 1536 | 172.8 GB/s M6000 | 3072 | 317.0 GB/s While we don't recommend cards for Nuke, on Linux it is currently tested against the K4000 and K6000 ( https://www.thefoundry.co.uk/products/nuke/sys-reqs/), which gives an indication of the range of specs we are mainly targeting when testing the GPU acceleration. While I wouldn't expect a BlinkScript that works on one machine to take hours on any other machine, unless there is a bug somewhere, I also wouldn't expect good performance from a Quadro K600 or 600 with any of our GPU-accelerated nodes, to be honest. We'll be able to give a more definitive answer once we've got your script in through Support. I hope that is some help in the meantime.
