R190 - jerking on IE, Chrome, Firefox, Opera

Bugs will be moved here once resolved.

Post » Tue Dec 02, 2014 5:16 pm

@Ashley scratch that... as I already stated the original capx works perfectly smooth in IE11. So there's no glitch in the acceleration parameter.

So maybe there was a less pronounced vsync issue in Chrome prior to what it is today? Maybe it was so small people didn't notice it as much. Not sure which NodeWebkit I am using - not sure how to tell. But I downloaded a previous version which made all my vsync issues disappear. Perhaps the acceleration parameter of the bullet behavior exposes the issue?

@Unknow01 - I am interested in this problem, but like @jobel says I need to be able to rule things out in order to make progress on the problem, and you still have not reported on IE11. In order to allow me to be as helpful as possible in bug reports I need all this information, which is also why it's in the bug report template. Opera uses Chrome's engine so doesn't bring any new information, and both Chrome and Firefox currently have known v-sync issues on Windows, but IE11 does not. Therefore if you test IE11 and report that it works well, that would identify that it's probably that you're just seeing known issues in Chrome and Firefox that others are seeing; if you still see problems in IE11, that would point towards a possible issue with the C2 engine, but without testing, I am inclined to assume you are seeing the existing Chrome/Firefox issues and therefore these are browser-side issues and not a C2 issue that is our responsibility to fix.

@Unknow01

Have you tested chrome canary? It's got really good vsync most of the time; if it fails try resizing the window. Here's the link:

What about the older version of node-webkit? If you are on r190, you can switch out the current node with the older, stabler one by swapping a few files. I wrote a guide on this here:

update-guide-fix-jank-in-r190-node-webkit-export_t119896

Don't expect firefox to work very well under any circumstances; it's by far the worst of current browsers, exhibiting unstable performance on anything more complicated than a simple web game. They're supposed to be working on this, but...

Ashley, if you think that it is not C2 issue - close this post. I tested around 10 HTML5 games on some game portals and not find jerking issues like with C2. I will take a look on different html5 creators.

@Unknow01 - I still need you to test IE11 to establish whether or not this is a C2 issue.

If I find someone with IE11, I ask him for test C2 exported project.

BTW why you can not test it yourself? In IE11, Chrome, FireFox and Opera?

I looked on v-sync issues between Chrome and HTML5 and not find so many about it. And because I can not focus only on one browser I think I will not stay with C2.

so I ran this on IE11, Chrome 39, and firefox31, windows 8.1

"jerky" is such a technically precise term. So this is what I saw

firefox: seems smooth but it wasn't working properly

chrome: it was jerky at the start and seemed to get smoother as things progressed (after about 5 seconds). sometimes this is worse than others. a clear jump at times.. so I guess that's jerky.. it could be as @Ashley said earlier... the JIT compiler is loading up.

ie11: it didn't have the jerkiness, but didn't seem as smooth as chrome when things were going fast. however it's hard to say what that was as it's too fast for me to comment. I doubt it would be noticeable in a game.

I am asking you to test it to help identify whether the problem is specific to your system or not. All these questions I am asking you are 100% routine and I generally ask them on every single bug report.

It may be worth testing Chrome Canary and Firefox Nightly as well, since I think both browsers have made improvements lately.

Ashley, I know you asked before. I tested it on two computers myself. Project was tested by my friends and some people here tested it too - and have same problem. So please, leave an idea that problem is in my system.

We will see if new browser updates will fix this jerks. Otherwise projects / games shere is something moving (ball, players etc..) will not be accepted by playerbase.

Tested again in Chrome (Normal/Canary), FF (Normal/Developer), IE11, and Node-Webkit.

The only platform that showed any 'jerking' was Firefox (of course).

At high speeds the movement of the ball begins to look less smooth because of the high contrast between it and the background, and the lack of natural motion blur.

On my monitor there is a prominent, distracting after image, but that is the nature of viewing fast motion on an IPS screen, not a glitch.

@Unknow01

Have you tried some of the built in template games (flappy bird, space shooter, auto-runner, etc...)? Do they 'jerk'?
