Hey @Myst_FuyZz!
So the answer is going to lie in how you coded your movement. If you travel forward at 1m/s and left at 1 m/s, our mind assumes we have 2m/s when really we have 1 still. If you factor in acceleration (Which most templates of movement do) it seems you will slow down if you are using physics, because you’re not ALSO accelerating… I don’t know it’s hard to explain. But the answer is going to lie in how you’ve coded your movement regardless, so if you need more help please bring us some screenshots of that!
