Yeah... the audio sucks. Anyway, some of your assumtions are wrong,especially regarding that 'random' german guy called 'Gipsel'... read my PMs..
and regarding the likelihood calculation...well gipsels app did that on the CPU as well.

So even if you move it to the GPU, you're still not getting the performance of Gipsels app.. it'll still be at least 20% slower(copmpared to those,running stock without tuning gipsels app for maximum output).

And that's already using my 'opt' app that only uses 2 sec to calculate the likelihood on the cpu(vectorized sse2), compared to the 5 to 8 sec that the stock app uses on my V8 5365 xeon...

Nice presentations. You don't have to be Steve Jobs for us to understand what you're talking about.

Hey, language please. These boards are supposed to be kid friendly ;-))
