I might've mentioned something similar previously on the forum, but I have been noticing very severe framedrops lately during preview on setups with monitors of different resolutions.
I first dismissed it as some isolated incident, but when I tried hooking my new beast mode laptop to a monitor (with different resolution than the laptop itself), it quickly became unworkable. A blank project with one platform object chugged along at 20 fps during preview. The moment I went back to a 1 monitor setup, it all worked again. Is this a C2 issue or a chromium issue?
Edit: This happened on all browsers I tested on (Chrome, Firefox, NWjs)
Had the same problem. I have three monitors and one is a 144hz monitor and for some reason all previews lags like hell when I try to run it on that one. So I have to turn off the other two to run the game smoothly. But I have no problem running the game on the other two even when I have all three monitors on.
But it's probably my graphics card that is the bottleneck here. What do you have and are you using high Hz monitors?
Develop games in your browser. Powerful, performant & highly capable.
Anonnymitet I only have two 60 hz monitors. I refuse to think it's the GPU. My main setup has a 970, the laptop that got the worst results has a 1060 optimus setup. While one could first blame it on the intel card, that screen was only duplicated. No such thing as any overload taking place. The moment I unplugged the monitor it ran butter smooth again.
It's a chromium bug, there's an open report. This mentions multi monitor trouble: https://bugs.chromium.org/p/chromium/is ... ?id=467617
If you have two monitors with different hz, vsyncing is going apeshit.
I think it uses the frequency of the "main monitor" to vsync even if the project is playing on another monitor with different frequency.
