hello, i am planning to make a city really big (like in driver or gta 3) but if i make the building just a little bit detailed the frame rate goes like really slow ! how can i make a city like this with people walking and cars riding and much buildings without frame rate slowdown ?

Level Of Detail. Outdoor scenes are all about LOD because you can see into the distance. Note that to use LOD you will need to split the city into chunks, compile the chunks separately, and then import them all into a single level as map entities. Look in the WED manual, in the second "Entities" section, to learn how to use A5's LOD capability.

hello, ive made now 1 house and converted into a prefab (it has no scg substracting!) and the framerate stays constant even if i make 10 houses of the same next to eachother.... could it be that scg substraction has something to do with it to ?

There is nothing fundamental about CSG subtract which would affect the framerate. However in general you should avoid CSG subtract because it tends to create really bizarre geometry; you can usually create much more optimized geometry by hand. CSG creating ugly/inefficient would certainly affect your framerate adversely.

its all about whats in view... like im making a big city... well first i hjave a neighborhood... it is about 150 houses... all map entities... then my roads and sidewalks make up about 400 map entities... then my pedestrians make up about 700 entities... my game doesnt slow down much... mostly because i made the clip range low... but im still working on fog to help hide it...

Would compilation of MULTIPLE "general" low detail houses as one map entity as a kind of LOD help you? Create a very low detail house suitable for all your needs, compile multiple houses of that type into one map entity and substitute a whole block with it, for example, whenever distance reaches a certain degree(Dont forget to do the way around when view gets near house block, tho .
