Uh... I've been trying to use the existing drivers for about 5 years. Never worked. I finally got sick of putting up with it and decided to try to fix it from the bottom up. I want 2ms. Buffering in a two-URB-deep approach is a minumum of 4ms. What miracle of mathematics will allow that to give me what I want? I don't have to jab a pencil up my nose to know ahead of time it will hurt. > From where I sit, I see your response as "I refuse to even consider > using that known-to-work solution, it's My Way Or the Highway." Tell me how a 4ms deep buffer will give me 2ms latency and I will eat my words. It's a promise. Monty ------------------------------------------------------------------------- Take Surveys.
