I think you're the one not understanding lol.
Server tickrate does not impact animations, recoil control and so on so those are all client side and easily improved by a higher fps cap client side. A lot of gameplay will overall will just be smoother and easier to control.
The higher the refresh rate the more information you can see.
It doesn't take any money to uncap a client side fps limit.
Technically since the image refreshes more often you'll be able to see the information the server sent you quicker. It'll still arrive at the same rate, it will just appear earlier on your screen.
Unless the implementation of this fps cap is fucked, it won't even take longer than 10 minutes to raise the cap, or allow uncapping.
