I'd also like to point out that I have a somewhat new but not top-of-the-line graphics card and it easily handles all the new graphics features without much impact on performance. Still they will be disabled by default in A11, as it's experimental and we don't yet know which hardware best supports which options. The real issue with performance is not graphics related, but definitely pathfinding and AIs (this is easily verified by using the profiler in game - F11). That said, I've played several multiplayer matches lately with up to 6 players and performance was surprisingly good (all humans, no AIs). Think of it like this; we're moving toward a completed game by adding necessary features, it would be somewhat counterproductive if we only focused on performance issues, because adding new stuff could introduce new performance issues, the game might never be finished. We currently put a lot of effort into finishing art and programming tasks, a similar amount of effort into bug fixes, and the leftover is performance issues. Not to mention that at least on the AI and pathfinding side of things we're currently waiting for 1-2 people to finish their work so it's hard for anyone else to assist
