-- [ Picked text/plain from multipart/alternative ] There is a quantifiable performance difference David, but as I said, the computational delay difference between 512fps and 1000 fps is all of 1 ms.
That is to say, @ 512fps the computational delay is 2ms between updates, @ 1000fps the computational delay is 1ms between updates. Is 1ms that big a difference, I would say not. If it something worth trying to kill yourself over to achieve, I also would say it would not be. On 2/16/06, David Harrison <[EMAIL PROTECTED]> wrote: > > Why are you sure you need 1000fps?
