What triggers Stage3d software mode in Chrome but not Firefox?

[Sarah Northway]

I've run into a beta tester who can run my Stage3d app correctly while in Firefox, but when he runs it in Chrome it can't find his video card (GeForce 8600 GTS, 2013 drivers - old but on this list), causing Stage3d to slip into uber-slow software mode in Chrome.

Short of telling my users to "try a different browse", is there something specific about Chrome or PepperFlash (newest version WIN 12,0,0,70) that might cause Stage3d to fail to see some video cards? Is there anything I can do about it?

Hi Sarah,

Would you mind opening a bug report on this over at https://bugbase.adobe.com?  When adding, please include the user's dxdiag report so we can try and test like hardware/drivers internally.  Once added let me know the bug number and I'll follow up.

Thanks,

Chris

Sure thing. I wasn't sure if it was a bug or just unsupported/old hardware, but it's good to know you're looking into it.

Bug ID with dxdiag is #3716991: https://bugbase.adobe.com/index.cfm?event=bug&id=3716991
