Just having the game open in this one map causes these lag spikes
I've searched for a while and have no Idea what can be the cause, many people were saying about shaders but I don't have a single one in the whole scene. Disabling all of the map meshes fixes the lag, but enabling just one of them causes it again.
I have another bigger map that does'nt suffer from this, runs smooth with no spikes.
Texture sizes are the same, no reflections or transparency, and I'm using occlusion and double checked if it was working. I just have no Idea what to search next.
Suggestions are appreciated.
