Hi all - I've been using PT LE with a Digi001 for quite a while now, and running into a lot of issues with CPU performance. Whenever I get more than about 8-10 tracks up, I start getting the dreaded "increase buffer size" error. I'm using DVerb and the BombFactory MultiTap delay in parallel on AUX sends. Typically I'm using EQ and compression plugins on the other tracks. I've tried all the optimizations as recommended by Digidesign to no avail. I've seen a PT performance test but I don't know what that entails. Can anyone give me a link to what this is? I'm running a windows PC with a 2 Gig P4, 512MB of DDR, and 2 120GB hard drives (one for programs, and one for data). The machine is networked, but there are no other apps running on the computer. Running Windows XP SP 1, and version 6.2 of PT IIRC. I'd like to benchmark this box to find out where the bottleneck is, and hopefully find some way to improve its performance without having to totally rebuild it or buy a Mac. Any suggestions would be greatly appreciated. I've been able to work around it by premixing and bouncing, or by applying the effects directly to the files, but this makes it more difficult to tweak the mixes and I'd really rather not have to do this. All the stuff I've read says my box should be able to do better than this, so I'm baffled.
