really poor performance in latest chrome version

Discussion and feedback on Construct 2

Post » Wed Jun 01, 2016 8:13 pm

On a pretty beefy computer and on my android/ipad devices, i'm getting really bad webgl performance in chrome recently.

tested construct r227 and r229
Chrome Version 51.0.2704.63 m (windows 10 64 bit)

In chrome im getting 31fps with 65% CPU
estimated img memory 25.6mb
collisions checks/sec 154(~5/tick)

in edge explorer im getting a solid 60 fps with only 9% cpu (and its defaulting to canvas 2D for some reason)
in chrome with webgl disabled, i still only get around 31 fps with 65% CPU

anyone else experiencing this recent chrome performance drops?

Why is webgl disabled in your Chrome? Does it have your GPU on the blacklist?

@justifun your events cause cpu usage, just check in inspector

@delgado - But its performing way differently in edge vs chrome.

Here's a pic of the debug screen. there's really not that much going on at all. There's 2 physics objects.

@glerikud - webgl is disabled in edge for some reason, not chrome. but canvas 2d in edge still runs this at 60 fps in edge, so its something chrome related.

Look at your print screen, you see small button on right side?

So I also get poor performance with Chrome and would like to know what it is?
This is particularly evident when running the inspector with the 'inspect' tab. My feeling is that Chrome struggles anyway without the inspector (compared to other browsers, Edge has never dropped FPS on me).

The above images are from running the same layout and any differences in object counts are purely incidental the FPS readings are stable. Chrome noticeably speeds up when switching from 'Inspect' to 'Profile', suggesting it is having major issues with the inspector?

I'd appreciate any help in modifying Chrome to make it work (assuming it is a local issue)?

Thanks
