I've always done my testing and previewing in Chrome and it's worked fine up until a few minutes ago, now for some inexplicable reason (despite multiple reboots), chrome webgl is down to 4/5 fps for even the simplest of html5 tests.
If I switch webgl off in Construct, then it runs significantly better. I then decided to do a preview in Firefox with webgl, and it works fine!!! I also went to some random WebGL programs such as this one
and I get 20 fps in firefox and 4 fps in Chrome, so it's not just Construct. I've got Chrome 18.0.1025.11 beta-m and Firefox 9.0.1.
Does anyone have any theories about how Chrome WebGL could suddenly get corrupted? Can someone chime in about what version of Chrome they are using? I haven't changed anything, or installed any extensions or plugins, so I have no idea what is going on.
Thanks for any advice,
