I've been making some tests with my fluid simulation(60FPS) and when I replaced every tick, with every X seconds(0.2) My FPS dropped to around 5-10.
I always thought that the every X seconds is speeding up my game as a similar function in Game Maker did.
Does C2 do extra processing and still check every tick and wait until that 0.2 seconds has passed?
Long time ago when I was using Game Maker it was really slow and the best trick was to skip some ticks when checking conditions.
