1st off you have to understand that Third Wire basically is one full time employee, TK with others such as artists/modellers temporarily sub-contracted where need be.
As has been already said TK is very community minded - look at what he has done in terms of opening the game structure etc. up. Now compare that with Il-2, LOMAC etc.
Plus he still brings his oldest games (SF P1 etc.) right up to date whenever he develops the game engine further - how many other developers do that?
here at CA in the downloads section is a good start.
TK doesn't have MP as very high on his list of priorities, in a sense you're probably lucky that it's got what it has as I suspect that the other option wasn't to include any at all.
As such many dedicated MPers find the options a bit simple.
what gfx card & CPU do you have?
Most LCDs perform best at their native resolution (for yours probably ~1680x1050) if your system can handle it.
