What makes you lack tick?

@apostolateofDOOM Let's consider a server sending snapshots 60 times per second. A client device that's not capable of receiving & processing more than 30 snapshots per second will either start lagging horribly or skip half of those snapshots. But the thing is there is vital information inside those snapshots, like hits registering, players dying, sounds getting triggered, etc., so missing any of that results in big problems.

I know there are devices that can handle very high framerates, but the vast majority of players have their fps drop to 30-40 occasionally or in certain areas. It would be impossible for them to process full server updates at 60 Hz in those moments so they would fall behind and not be able to catch up with the server for long times, if ever.
