We should troll the mwo boards like" you got a kick ass system, OH you gotta try mwll.
As much as I appreciate the enthusiastic sentiment and share it in kind, I must ask to all, please don't.
you'll get an upgrade kit with 4gig ram, at least 4core cpu, and mainboard for 250 bucks here and then you need just a recent or a little bit older graphics card.
so you can't say you need a high end pc. this would be for me a dual cpu server board or similar, which is much more expensive.
the problem is, that i think we got big maps with a LOD engine (Level of detail) theese engines always need a good multicore cpu, although you could implement it all on gpu side...
if that is the reason, then i could offer me to optimize it, i have at least some experience in building opengl shaders. IF we can lay a hand on this part of the engine....
