Right, the issue is that 60Hz is ridiculously slow. Ethernet hardware is multiple orders of magnitude faster. It's just because of broadcast TV and CRT legacy.

Right, the issue is that 60Hz is ridiculously slow. Ethernet hardware is multiple orders of magnitude faster. It's just because of broadcast TV and CRT legacy. G-Sync / FreeSync allow up to 240Hz, which is ~4ms latency.
- thomasahle 9y ago60Hz is 16.7ms between each picture. However, that only gives you a lower bound on the latency. The actual time from GPU sending picture, to picture being on screen, can be a lot more. See the John Carmack answer above.
- CyberDildonics 9y agoNo, the issue was that he was using a display with a crazy amount of buffering because they were doing so much filtering and doing it poorly.
- Retric 9y agoIt's not just monitors even keyboards can have 40+ms worth of delay and it all adds up.
- CyberDildonics 9y agoI don't think that was what he was referring to
- Retric 9y ago"I video record showing both the game controller and the screen with a 240 fps camera" https://superuser.com/q/419070/2269 https://superuser.com/q/419070/2269 So, it's total response times from key press on a game controller to screen that is important not individual components. Sure, 0.04 seconds on it's own is not a big deal, but when 5 or six things take 0.04 seconds you hit noticeable delays.
- Sephr 9y agoG-Sync and FreeSync have nothing to do with the available maximum refresh rate on any monitor. That is a property of the display interface.
