rich Posted October 3, 2013 Share Posted October 3, 2013 Anyone else noticing this, or is it just my PC? But since Chrome auto-updated to version 30 (30.0.1599.66 m to be exact) canvas AND WebGL performance has been horrible. I'm getting noticeable redraw lag in things that used to run super smooth. Happens with pretty much anything I try, so it's not confined to a single codebase but appears to be more of a GPU level change. Naturally enough my PC/GPU is working fine in all other regards including high-end games. Edit: Here's the fix: Go into Chrome flags and set "GPU compositing on all pages" to Disabled.

ben0 Posted October 3, 2013 Share Posted October 3, 2013 I have 30.0.1599.66 too, haven't seen any drop in canvas so far (60fps, as usual). What's the game you're testing Rich? Quote Link to comment Share on other sites More sharing options...
mentuat Posted October 3, 2013 Share Posted October 3, 2013 just updated (30.0.1599.66) and seeing the same issue, current game was smooth yesterday (60fps), jerky today (35fps but looks worse) Quote Link to comment Share on other sites More sharing options...
vids Posted October 3, 2013 Share Posted October 3, 2013 Yup, same here. Quote Link to comment Share on other sites More sharing options...
sbat Posted October 3, 2013 Share Posted October 3, 2013 My games seem to work fine on the updated Chrome, but as they are targeting mobile browser and always performed well on desktop. Quote Link to comment Share on other sites More sharing options...
rich Posted October 3, 2013 Author Share Posted October 3, 2013 Just reading the comments on the Chrome Release blog and it appears this is a known issue: http://googlechromereleases.blogspot.co.uk/2013/10/stable-channel-update.html Quote Link to comment Share on other sites More sharing options...
Ezelia Posted October 3, 2013 Share Posted October 3, 2013 having random lags here ... sometimes it runs at 60fps then randomly drop to 30 .disabling GPU composing fix the problem Quote Link to comment Share on other sites More sharing options...
rich Posted October 3, 2013 Author Share Posted October 3, 2013 I'm experiencing LOTS of other problems with it though. Tabs will randomly freeze, the History is taking minutes to load (causing a "Oh snap!" error in the process), when you search from the address bar 9 times out of 10 the page will never load and it will loop forever. Icons on my Bookmarks bar often don't load the page either. If I've got Dev Tools open very often non-visible browser tabs will hang too. It's about as close to being unusable as iOS7. No easy way to revert version either, so going to have to swap to Firefox until they sort this mess out Quote Link to comment Share on other sites More sharing options...
AshleyScirra Posted October 3, 2013 Share Posted October 3, 2013 I can confirm Chrome 30 also affects Construct 2 games. Our performance test (http://www.scirra.com/demos/c2/sbperftest/) now scores about 30 (avg. FPS) instead of 60 in Chrome, whereas Firefox and IE score 60. I tested Chrome Canary (version 32) however and it seemed fine - back to 60 FPS. So I guess they've already fixed this - just need to wait out an awkward 6-12 weeks of games running at 30 FPS Hopefully we can persuade them to patch the live stable version, but I think they're wary of doing that unless it's an important security fix.

rich Posted October 3, 2013 Author Share Posted October 3, 2013 Thanks for confirming Ashley. It still amazes me how a product like Chrome, with all the resources Google has behind it, have such a major screw-up as this. Next everyone will start crying "conspiracy! it's because of their app store! they hate html5" Quote Link to comment Share on other sites More sharing options...
AshleyScirra Posted October 3, 2013 Share Posted October 3, 2013 I don't think it's really a showstopper bug though. It's a shame and looks a little ugly, but at least most Construct 2 games are framerate independent, so will play out more or less just the same but not quite so smoothly. And we know a fix is on the horizon, which is quite a relief compared to, say, not really knowing when iOS 7 issues will be fixed. Quote Link to comment Share on other sites More sharing options...
Psychho Posted October 3, 2013 Share Posted October 3, 2013 Iv got no problems whatsoever even with GPU page composition enabled, games run at the same speed they always have too. Quote Link to comment Share on other sites More sharing options...

It's not a showstopper in itself, but all the other problems I'm having with v30 certainly are. Learning to love Firefox again Quote Link to comment Share on other sites More sharing options...

captainherisson Posted October 3, 2013 Share Posted October 3, 2013 I might add that chrome 30 on android (still beta) is also a catastrophe. I tested it on multiple nexus devices and noticed a huge performance drop. Quote Link to comment Share on other sites More sharing options...
captainherisson Posted October 4, 2013 Share Posted October 4, 2013 Issue fixed, stable version have been patched:https://code.google.com/p/chromium/issues/detail?id=262437 Pfeew! everything is back to normal Quote Link to comment Share on other sites More sharing options...
AshleyScirra Posted October 4, 2013 Share Posted October 4, 2013 Awesome. Confirming fixed in Chrome 30.0.1599.69. Not a bad turnaround time considering we only noticed yesterday Quote Link to comment Share on other sites More sharing options...
