Sony's illustrious VAIO Z may have a so-called "Dynamic Hybrid Graphics System," but NVIDIA's Optimus it is not. Or is it. Notebook Review's own igorstef started digging deeper within the laptop's switchable GPU setup, and lo and behold, it sure looks as if Optimus is underneath. He went through the painstaking process of installing a slew of new drivers and tweaking some code within select .inf files, and in the end he seemingly found a way to get Optimus drivers working on the new rig. Of course, the debate has been raging on for five pages now, and it still seems inconclusive as to what's really going on behind the scenes. In related news, ZoinksS2k seems to have discovered a way to get Windows 7's TRIM feature working on his SSD-equipped VAIO Z, and if you're interested in doing some tinkering of your own in either case, you know where to dive in.
