We've all seen that too many objects on a map can make it flash, slow the frame rate etc. But do invisible objects such as respawn points, hill markers and game specific objects from other game types contribute? If, for example, I added race and rally markers to my slayer map, would the extra objects adversly affect other game types even though they can not be seen?
They shouldn't. The game doesn't have to actually render anything for those objects, it just needs to know where they are. In fact the proof is evident in the difference between forge and custom games - in forge (especially basic editing, with all objects showing) you will often get frame rate issues that aren't present on the same map in custom games. So if there is a performance hit from hills, respawn points, etc. that aren't actually rendered, it's quite minimal.
Cheers. The reason i ask is that I am deciding whether or not to add all game typs to my map or just the core btb style games. If there are no adverse effects, I may as well add all game types.
Anything that is 3d that appears on the screen will affect performance. Hills do have an effect on performance, but it's probably negligible. Spawn points don't because they are not rendered during normal gameplay.
In forge, spawns, respawn areas and everything like that cause tremendous amounts of Lag... In custom games, the only thing that has a holograph interface (like hills etc...) are the only items that can cause lag because they are visible. All other things like initial spawns (That trigger a whole load of lag in forge) don't contribute in the slightest as they aren't visible.
