Topic: How can I improve the performances of my laptop?
I have just upgraded an old black Macbook (Core 2 Duo - 2Ghz / 2GB of RAM) to Windows XP Pro SP3 and Mac OS X 10.6.2.
Initially, I tried Windows 7 Ultimate 32-bit and it worked, I could get the Fireface 400 work at 64 samples with Reaper, Max, Pure Data, Audacity, etc. It was necessary to disable the wireless network driver and to switch the user interface to "Basic" mode (the one that is similar to the full-featured Aero, but without the transparency, effects, etc).
But the performances were limited therefore I have replaced it by XP for now (the wireless network still being disabled).
Overally, this laptop works better on XP than on OSX for low latency audio applications (64 samples), but the maximum possible CPU load without getting any crackle is still far from 100%... While a friend had the same laptop on XP (SP1 or SP2) and it was really more reliable.
The DPC Latency Checker stays in the "green" zone, usually around 100 microseconds, with some occasional spikes at 500-1000 microseconds. These occasional spikes are still in the green zone, but ideally they should not occur...
I do not know if it's possible to get better performance on this laptop. Disabling as much drivers as I can (even this new, useless and unfancy "IDT Audio" thingie) does not change things. Any idea?
Thanks for your help
