well,I use dbp. I did use dbc a while back. Dbp is faster on a lot of parts,but I used dbc for creating a basic first person shooter. If you have trouble with dbc,you can create plug-ins. I've started learning c++ a ways back,and I can now write plug-ins for it. I am starting with directx so I can use stuff like that(You can use dlls if you have dbc enhanced,which I think is an upgrade(free)). But,to answer your question without blabbing,yes,too many objects would cause lag. Objects very complex can generate lag with lighting. When I used dbc,I tried using a halo 1 level(hang 'em high),and it lagged so unbelievable,I felt like crying. Take your time to learn dbc,then,if you have money and stuff,buy darkbasic pro. It is overall better(Yay of udts!!!). But you can create pretty much the same stuff in darkbasic classic. Hope I've helped somewhat.
