I just bought my first mac yesterday. I got the 15" MBP, with SR. Unfortunately I need to use Autocad, so I installed bootcamp 1.3 today and in the windows system profiler under the adapter ram it says 512MB. The OSX side still said 256MB. Adapter Type GeForce 8600M GT, NVIDIA compatible Adapter Description NVIDIA GeForce 8600M GT Adapter RAM 512.00 MB (536,870,912 bytes) Has anybody else noticed this? Is this a glitch?
