I just bought a Apple 2019 27 in iMac 3.6GHz 8-core i9 64GB machine to see if it fixed my issues I had with some objects messing up and video flashes. It seems to have fixed those fine. But the problem is Chrome. I am getting like under 5 fps on webgl scenes that should be at 60. They work fine in Firefox & Safari at 60 fps. My 2013 iMac plays at 60 fps
Anybody with a mac has similar problems. So bummed out…
That page for example is dead slow in Chrome. My card is a RP580X 8GB not the Vega. Was thinking of sending it back for one with a Vega. If you can tell me if yours runs ok, then if I switch this should to…
I take it back, it’s probably due to this weird thing going on with the render to texture. Looks like you’re also rendering to a cubemap? It’s showing over 5 million vertices drawn in a frame written to different buffers.
Also the 14 clear calls may also be affecting things.
Well the thing is, it looks just fine in safari,Firefox,edge, which is why I am at a loss. The objects are glb and stl, doing the same. Not all objects are doing this, but three show the problem. In chrome anyway
it seems you have run into this chromium issue, which I filed a while back. it appears to be related to this issue which affects webgl on Intel Macs in Chromium. Apple changed something around 11.6.4 that broke the newer WebGLRenderer. but WebGL1Renderer still works. so I added this to my code to work around it.
// workaround for https://bugs.chromium.org/p/chromium/issues/detail?id=1321452
let Renderer = nav.platform === 'MacIntel' &&
nav.vendor.indexOf('Google') >= 0 ? WebGL1Renderer : WebGLRenderer;
Unfortunately, you can’t detect M1/M2 vs Intel in the browser, so MacIntel catches those, too, even though they are not affected.
