For some reason the UNSC Wasp adds 10% to the fx budget, but no other land/air vehicle does this. Is there a reason for this and is it bad to go over the fx budget?
Hmm, that's weird... maybe the smoke effects when it gets shot? I wouldn't stress out on the FX for the Wasp pushing you over - just make sure the other things on the map don't go above 100 on their own to dodge performance problems. You can go over 100%, I believe, but you'll need to test the map carefully at that point to be sure there's not any weirdness.
You can go ove 100%, I wanted to see if there was a limit and spammed wasps till about 212% I was just wondering if it was glitched or what because no other vehicle causes the fx go up by 10%
