I have the stock radeon 9600xt… could that be making the difference? It’s my understanding that emitters rely heavily on the processor. I don’t know much about Open GL though, so I’m not sure what else to try!
It renders fine in 8 bit though. However, there’s a noticeable difference the smoothness and realism of the smoke in 16 bit and that’s why I was hoping to use that version. On the HDV output it makes a difference. Again, it’s probably a case of my wanting to tweak with something that looks okay.
Thanks for your response!
