geforce 320m driver causing latency (ableton)
Hello,
I have latency problems on my brandnew macbook pro (2010, with geforce 320m card)
I use my mac for making music and live performances, and I use windows 7 professional.
After various hours of trail and error I figured out that the nvidia driver for windows 7 is causing the high latency, the audio is much 'slower' compared to my other white macbook (from 2007). I used dpclat.exe (dpc latency checker) to determine the latency and i disabled devices one by one and the latency is more than OK when I use the standard vga driver of windows 7 instead of the nvidia one. To bad my external monitor doesn't work with the standard vga driver.
While googling i stumbled upon people talking about the 'powermizer' functionality or that the videocard is switching between 2d/3d, which could case the high latency spikes.
Anybody has a clue to fix this high latency? Or if there is a new decent driver for the geforce320m is in development?
Overall i'm very happy with the macbookpro but this is just strange.
(Update: I also tried windows xp but it has the same issues, also the driver causing the high latency spikes)
