@GenkiGenga, it's a good idea. I just closed everything else down, double checked that both Chromes were up to date.... But dt is still frozen in Chrome. Weird...

Very weird... was worth a try I guess. I hope someone can come along and make sense of it.

OK, the http://www.vsynctester.com works well for me in Chrome.... So it might be a peculiar bug for my hardware v Google's finest. I just don't understand why vsynctester can register dt but c2 cannot....

I've submitted a chromium issue report for the crashing of the developer tools.

Hm. I'm getting consistent jank from your camera pan test and that vsync test website in Chrome. Significantly worse in Edge.

I've heard a lot of people say the vsync/jank issue has been fixed but..er...it hasn't? It's gotten a little better but it's still very noticeable.

What's Jank?

I did google it but got a wide variety of possible explanations.

@Tokinsom, it's got to know that it's not just me! Do you see dt varying or does it appear fixed?

@OldieSteve, jank is apparent stuttering of the browser display, movement that doesn't appear smooth due to frame drops.

Tested it with Chrome.

i5-3570K with AMD R290X.

Zero jank, perfect 60 fps and 0.016ms timings.

I have to add, in the past when I was testing performance, C2 would have stutter with Intel iGPUs, repeatable. But it ran fine on AMD GPUs or my NV GPU I had at the time (GTX 670).
