CentOS 7 3D acceleration -- slow

I have reasons to believe 3D acceleration in a CentOS 7 guest is still being via software rendering.
gnome-shell takes up a ton of CPU via 'top', moving windows around on the desktop is chuncky.
I'm using VB 4.3.12 because 4.3.14 is broken. But I did use the 4.3.14 guest additions.
Anyone else seeing this? Anyone have a solution?
Also, running 'glxgears' will display the gears, but will hang X. the only way to get it to recover is to Cntrl-Alt-F2 and pkill glxgears.
Can anyone confirm glxgears breaking things?

If you are using a Windows host you will have to wait for a new version. If you are using a Linux or Mac host, 4.3.14 works fine.

btw: if the gears turn 3D is working or if you run
and in the results it says "Chromium", 3D is working.

It sorta works. The gears display, without window decoration, and the X server freezes. This is not normal behavior... and i wouldn't call that "working"

I actually said "turn" not just display. which is why I included the other command to try. My understanding was one needed both VB 4.3.14 and the matching guest additions for CentOS 7 to work correctly and the guest additions to build correctly. I don't normally run CentOS anything but I installed it as a guest a couple of weeks ago to see if it worked. It worked fine for me even with 4.3.14 RC1.

Yes, it displays and turns. I would try 4.3.14 if it wasn't a big pile of broken. I'll wait to see if the next release works and give it a try again.
And 'glxinfo' does show 'Chromium'. But it still causes X to freeze.
I'll wait and try 4.3.16 and see what happens.

If you have a Windows host, I would wait as well. Seems fine on Mac and Linux hosts.
