I get tearing using Chrome, and under "About This Mac" and System Report, it only shows 6MB of VRAM. The only difference between this one and others that I have working, as far as I can tell, is that this one with the issue has an SSD, and the other do not.
I just setup another 9020, and the full 1536 of VRAM is reporting on it. Would there be any issues if I throw this hard drive in another 9020? Will it just work? Or is it like Windows and screws up if the MAC address is drastically different? Thanks. Also, remember to port your reply AFTER the quote
