After reading the TimeDelta wiki page, I wanted to make sure my game won't suffer any problems when it comes to computers with varying performances. So what I did is follow the wiki and set the Framerate Mode to unlimited FPS. After doing this, my game ran at ~500 - 1000 FPS and everything ran fine (though I don't have any TimeDelta commands since everything is behaviour based). Everything ran fine except for the fact that the particle rate increased dramatically.
Should I be worried about this and try to limit it? Or it it normal for particle rates to increase when setting to unlimited FPS? The game is going to be V-synced and locked at 60 fps, so it shouldn't be a problem, correct?
Everything in terms of speed runs the same with unlimited FPS, so all is fine?
EDIT: for those wondering, the particles are done like this
Always (every tick) > Bullet: Spawn object 'Bullet_trail' on ...
