It requires DirectX 9c by the way, sorry i forgot to mention that, it could be that or it may be its just not a 3D card...oh and as far as framerate..i set the screensize to 800x600 and gained 20fps...also the particles are the real slow down, i set the inteligent particles off and the fps didnt fall below 230, and when i turned the smoke off completly it didnt fall below 270 peaking at 330ish....so looks like ive got some optimizing to do, and inquiring about a little problem i have.
The Walls now can be deep as well as wide and high, just a little update as i was posting !
