On my computer in my room, it was almost impossible to play AA 1.9! Whenever I would encounter an enemy, my FPS(frames per second, not feet!) would goto 0 for a few seconds. When it recovered, I would be dead. Really not that much fun! If they want to decrease lag and improve preformance, they need to make them low poly models! Not focus on the looks but on the preformance and game play. And instead of spending a few months on modeling a new soldier, stick to the old one, add what you need, keep the FPS at a reasonable ammount, and add new things that actually matter (IMO) to the gameplay!
