Well we have no big questions yet but this sounds great. Hm we need some coders, well as someone how can make the undertext (i hope this is the right word) this could be very difficult because we want to make it like Knights of the Old repuplik with many things you can talk aboutâŚ-.-
Well with this HD texture, its really not that heavy, We textet it several times and what comes aout is that it only takes maximum 8 % of frames also there are many different of them the only thing that reduces Frames per second is vertices. So i hope we get the right amount of Vertices. All other thing are no Problem at all.
What could be a problem is Alpha textures like grass an so on this makes Frames very low so we must develop a way reducing themby distance like Lod and other features.
We gonna Rock the engine really 
But i understand taht many would say, well taht can not work i could not belive it but i have seen working it it is not my first time project ^^
Edit: THANKS MARTINSH FOR YOUR GREAT REALTIME FILTERS ITS BETTER THAN IN UT 3 !!
