I would have agreed if Windows had offered developers an easy way of prioritizing threads and processes. But as far as I know it doesn't (or developers don't know how to use it). In my experience the performance of a PC with 90% CPU load is miserable for all processes running on it. With that said, I don't see why PowerSDR should incur that kind of CPU load on a 3GHz machine. I am running XP home edition on a dual core Dell at 2.9GHz and 2Gb of RAM. My CPU utilization is hovering between 15 and 30% with all of the following running:
LP-Bridge HRD PowerSDR with EMU-0202 sound card at 192ks/s VE7CC cluster client (highly recommended) Iexplore composing this message Thunderbird mail client DX Atlas I can add more applications and the CPU barely nudges upwards. I think most people would agree that a car that has to be driven always with the accelerator nearly to the metal is underpowered and not much of a joy. I am a firmware developer and we always worry whenever the CPU utilization exceeds 50% even though we use OS's that allow intelligent prioritization of tasks.
