Pixio PX277 not smooth at non-native resolutions
I just made a discovery about the Pixio PX277 monitor, using the latest firmware M270QHD V07.
When playing at 2560x1440 @ 144hz everything feels smooth and crystal(ish) vision so long as I maintain a high framerate. However, once I switch to 1920x1080 @ 144hz suddenly that smoothness goes away, and it's very noticeable when engaging in fast motion close quarters combat. The monitor and the game are reporting 144hz, but something about the gameplay just didn't feel as smooth visually as when I was in 1440p.
I solved this by enabling GPU Scaling in AMD's options. However, enabling GPU Scaling creates noticeable input lag when using the non-native resolution (2560x1440) but now at 1080p (and I'm assuming lower resolutions) everything feels as smooth as butter. The input lag, while noticeable, might not be that impactful on gameplay however. It seems that you just need to have more prediction in movement to make up for the extra few ms of input lag.
I'm not sure, but I think this might be a monitor issue. It doesn't rescale well perhaps?
