works for me with that exact text. 'System Information' app in the guest shows 15MB VRAM.
When I set the values to my VMX file, the log file says could not retrieve the vramsize and hence setting it default value! Using vmware9 with 10.8 guest on windows 7 x64 host. Any inputs?
Same setup as yours, except host is Windows 8 x64. However, I've tried this on Windows 7 x64 as well and I'm sure it worked.
