Block Build/Explode Smoke Effect Overdone
Grinding/Welding/Exploding block create FPS drops with the block status change (smoke effect)
Setting "disable damage particle effects" is not working for this. If block explodes for 2 seconds you will have 5fps until the "smoke effect" disappear. Then then 120fps with random flying trash and bend iron plates.
Funny that drill block is working fine at 120fps all time with all that smoke and particle effects it produce.
