    Hi, I have recently got the baseline 2012 15" Macbook Pro.
    I have been playing some games on bootcamp, and I noticed that games like GTA 4 are reporting 458MB of VRAM instead of the supposed 512MB.

    Is that normal? Or should I go to an Apple store and request for a warranty claim?

    My Nvidia driver is 310.90 WHQL running on 32-Bit Win7.

    I have not checked rather this persists with other drivers.

    Both the nVidia control panel and Techpowerup's GPU-Z are reporting 512MB dedicated VRAM, but things like Steam big picture, GTA IV etc are reporting 458mb. Any advice?

    Yes, because your OS needs VRAM to display desktop elements, hence less VRAM is available for your game.

    Spot-on. If you want a small boost, I'd suggest you get a program called Tune-Up utilities. It has a "Turbo-boost" option that turns off the OS 'fancy' graphics, delays indexing, and some other nifty things that will give you a better performance. Alternatively, you can just find these options manually and turn them off.

    Ive heard of solutions like eGPU if the dGPU is being a problem for you.
    You can install AMD Radeon 6870 for your Mac.

    Thank you all for your reply. I think I can put my paranoia to rest :)
