As with anything, every time you put something into a game, it takes more to get it back out (processing, graphics, audio drivers, etc.). But at the same time, I'd really like to see some improvements in A3 over A2, such as light not shooting through opaque objects, and light fade over a distance. The A2 flares and NVG effects, as well as it's post-processing effects, I found to be quite good as they were, but a few tweeks here and there would be an incredible improvement in night-based OPs.
