FPS Lag

So i’m using occlusion culling to try and combat the lag spikes i get from time to time while walking but that doesn’t seem to help. It’s not all the time lag but it’s noticeable in certain sections pretty much the same sections everytime where I get a huge fps drop to the point the game basically stops for like 2 sec and then start back up its only every once in a while and not at all common place but enough to annoy me. will this resolve once the game has been built? or is there anything i can do to cease this incessant fps drop.

Try building.
