Still no improvements
Affinity and Priority
I wasn't able to change either the affinity or the priority. I started the Fiesta client, then switched to the Task Manager and tried to switch both. Neither worked giving me some error not allowing me. I don't have the exact error, but I got the impression that perhaps it was complaining because I was running the program at them time. Is there a way to set these setting for Applications/Processes *before* they are running ? This would seem counter intuitive to me :/
Video Card Drivers
Remembering that *all* of my problems started after Vista SP1 installed, I didn't think this was an issue. I went to the vendor website (NVIDIA) and saw they had updated drivers for my card as of May '08. I tried to install them, and it errored, telling me that I had to download my NVIDIA drivers from HP (the make of my laptop). I went to HP's update site and say the most recent drivers there were from sometime in 2007! So HP thinks I *do* have the latest drivers, but I kinda doubt this now

... but again, this was *only* a problem after the SP1 update, so whatever drivers I did have were working fine before that!
SP1
I have not actually rolled this back yet. I will likely try this tonight or tomorrow...will post again once I have more info
