I have encountered the same issue with the mp ocx being slow at drawing on a dual core machine. MP simply cannot keep up with my requests (unless I set the App and ocx to run on the same CPU). I also noticed the performance is significantly worse when using the flat view vs globe view...

Since my customer is still running MP2004 on a Pentium 4 (single core) machine, I havent had to provide him with a solution yet, but he is planning to upgrade his systems later this year, so my clock is now ticking...It will kind of defeat the purpose of the upgrade if he can only utilize one of the CPU cores.

Does anyone have any more info? Any word on if this might be fixed in the next version? The feeling I get is that MS is not doing much to fix or enhance the desktop version of the product.
