Thanks for both of your replies, I looked into how Delta Time worked and came up with a different solution - I changed most "every tick" events to "every 0.0167 seconds", which is near enough 60fps translated for any refresh rate. This is nice because I can now do the same to my older games, which I had designed whilst only using a 120hz monitor, and are most likely partially in slow-motion for 60hz monitors.
Be verry careful when you do this. Especially if you are thinking of selling on steam. There are verry high profile people who will trash your game if it is not to their expectations:

Don't worry, I'm not this stupid. I don't sell anything on Steam that I make and if I did, that's the last thing I'd do. I can't play FPS games in anything under 100fps on a 120hz+ monitor, and I hate games that are even locked to 60fps for the most part. (I used to watch TB too ;D)
