I have a relatively new machine that has a P4 with Hyperthreading. I've recently installed Shredder 8 and Gandalf 6. When playing a match I switched to the Task Manager to look at the memory usage and noticed that when Gandalf was thinking, according to the TM, it was only using 50% of the CPU while Shredder 8 was using 100% (both had Ponder = off). On further investigation Shredder was using 2 threads in the engine. Looking at the speed, both were getting approximately the same nps which is inline with other machines I have tested them on. So the question is - does the Task Manager report the CPU resource usage incorrectly in this situation i.e. 50% = 100% usage of 1 processor? I'm reasonably sure that this is the case but wanted to check. Thanks, Steve Maughan
