Hello guys, can someone explain to me or give me some source of info on what affects performance most? I know that polycount, uv seams, drawcalls on ue4 and texture numbers/ sizes all affect a game"s performance, but I dont know to what degree nor have any reference so I generally dont know how to model, how much to cut on my geometry and where to use more geo for detail.
1)How much performance does a texture take?
2)is it better to have an rgba texture instead of 4 same sized 1 channel textures?
3)what about material instances?
4)Do you keep track of your vertex count with the uv seams in an engine?
5)How many tris does a close up environment can take before the LOD"s kick in?
6) How much with hq and LOD alltogether?
7) do all the above get expotentially heavier the more lights iI place on my scene?
I have literally no clue about any of these technical information, so if anyone can give me some insight/sources/books to read about that, i'd really appreciate it!!
