Tick rate no longer matters for moving, shooting, or throwing.
Sub-tick updates are the heart of Counter-Strike 2. Previously, the server only evaluated the world in discrete time intervals (called ticks). Thanks to Counter-Strike 2’s sub-tick update architecture, servers know the exact instant that motion starts, a shot is fired, or a ‘nade is thrown.
As a result, regardless of tick rate, your moving and shooting will be equally responsive and your grenades will always land the same way.
