I just bought a new system after hearing all these great things about dual-processor systems being hot for DV work. I was getting sick of the old Dell not being quite fast enough so I found my current system for a great price and picked it up. You can check my computer details for more info but otherwise I have two Athlon MP 1900+ on a Tyan 2460 mobo. On my old box 1.6GHz P4 TMPGEnc clocked the CPU right up to 100% when doing encodes (or at least according to the neat little display in the task manager). On the new system I get peak 64% from both CPUs and I'm only decreasing my encode times by a small amount. I wanted at least a 25% reduction in encode times. Is there some sort of limiter built into XP or TMPGEnc that I don't know about? If both ran at 100% I'd probably almost cut encoding times in half. I haven't done a benchmark between the two (I still have the P4 handy) to see for sure if there is much of a difference between the two. I do have a PAID version of TMPGEnc, latest edition. Which CPU options should I have flagged in TMPGEnc?

Anything else I should be comparing between the two systems that could make a difference. In almost every aspect the new box has the old one beat so it can't be hardware. Maybe I'm missing a codec that's making a difference? Doesn't sound right to me though.

Thanks!
