@sk1lld Basically the server is only sending and receiving updates every 50ms (compared to every 22.2ms for a 45Hz instance). So theoretically, the game is updating less than half as many times per second.
I am playing anywhere between 120-140fps, my ping to the server is 25ms, but to compensate for the slower server tick rate, the game adds a time nudge (TN) to my client (in this case 34ms) to put my client in line with the server.
That makes the game borderline unplayable. EVERYTHING is delayed and jerky. Kills happen late, it feels like you are playing several frames behind.
I honestly didn't know they could even change it as I have only ever seen 45Hz. The fact that they can change it is frustrating as we should be able to go to 60Hz or 30Hz in Portal.
60Hz should be the minimum for BF at 64 players or less. 45Hz is bad, 20Hz is worse. 30Hz would've been better.
