So, I think I got backwards-deck. I play Rocket League, so input lag is a big deal for me there. However, the issue I have seems opposite of what I see online:
- Using deck controls has noticeable lag
- Using a wired X-Box controller has noticeable lag
- Using a Bluetooth X-Box controller works pretty good
Can anyone think of why I would have such bad lag on the built-in controls?
EDIT So this might be display, not input lag!
- Set Gamescope Disable FPS Limiter On
- Set Gamescope Allow Tearing On
- Set Rocket League Vsync Off
- Set Rocket League FPS to 144
The deck works a lot harder, and fans go crazy, but it’s playable without an external monitor now. I think in limiting to the didplay’s 60hz, the Deck must be doing something else causing display lag.
That’s really bizarre. A lot of rhythm games have a calibration test you can do for both visual and audio lag, the visual lag test would be a great way to get some time measurements of the lag with different controller types.
Edit: Rift of the Necrodancer has a free demo that includes a visual latency test.
Oh perfect, see edited post for a partial solution (so far), I will use this game to test my findings.
