kind of same here, i have a 2011 macbook pro and a PS4. I installed virtual box yesterday and setup a Windows 7 64bit, dedicated 4 cores from the i5, 256MB VRAM and 5632MB RAM. Downloaded de the benchmark and directx 9 but it says it has directx 11 and there is no need for new install. But when i run the benchmark it says directx fatal error 10000000 which i am inclined to believe it is something related to the graphics card after reading some stuff on the net. Not sure if this is the thing or not.

I installed the extensions on virtualbox but nothing on the W7 install besides the windows updates.
