Well, I tried running Pathfinder today on my laptop and it was horrible. Click something in the Tactical Console, wait around for it to respond, click the next thing in the Tactical Console... It literally added an extra hour to the fight.
Afterwards I tried rolling back to 8.8, but it didn't work because I had updated Pathfinder.
Edited to add: I played around with it in Savage Worlds, M&M3 and 4e and it seems to be a Pathfinder thing (at least among systems I own).
