You can't specify which logical processor does which process.
if you do indeed have a CPU with hyperthreading enabled then to view 2 CPUs in task manager click on the performance tab> view> CPU history and select one graph per CPU.
I use this method on MS Flight Sim 2004, here's the prodecure copied from my tweaks manual:
After starting FS, go into task manager (CTRL_ALT_DEL) Select Processes tab Right click on FS9.exe, select "Set Affinity" Disable one of the two check boxes so that FS9 only runs on one virtual CPU. Do the same on any other running utilities and select the other virtual processor.
Users who run a lot of extra software report as much as a doubling in frame rates. This, of course, assumes that hyperthreading is supported and enabled on your motherboard and BIOS settings.
So the same applies except the program listed can be something else.
That's a cool concept. But is FS dual processor aware in the first place?
If it's not then maybe it's losing some performance dealing with a dual setup
to make such an impact by designating a single CPU. Otherwise, I don't see
why a program that is dual processor aware would perform better by going to one.
I haven't used the Set Affinity setting yet so it will be fun to check it out.
Thanks for the heads up on that one LS1Chris.................TD
I think the reason this trick increases performance is because it essentially provides a virtual CPU exclusively for FS. All other tasks are being setup on the other virtual CPU. This means that all sorts of interrupt requests assocaited with other background tasks won't need to be serviced by the virtual CPU that is running FS.
So you're saying that by assigning a process this way isolates that process to the selected processor and keeps everything else on the other? This is worthy of some Intel white paper reading. Very cool........TD

^^^^exactly the point.
Is the AGP Aperture set to 64mb default with my Nvidia GeForce FX Go5200?
