At the heart of the Erazor X is an NVIDIA GeForce 256 clocked at 120MHz. The most talked about feature of the GeForce is, as you most likely know, its hardware transformation and lighting (T&L) engine. This engine offloads many geometry and lighting calculations from the CPU, freeing it up for AI and game play calculations. It can also process T&L functions significantly quicker than today's CPUs, so game scenes that support hardware T&L can have more complex geometry without a severe performance drop that would otherwise occur. This also frees up the CPU for more AI related calculations, for example. There is a weakness though, not all games support hardware T&L, and of those that do (most OpenGL and DX7 games), not all make good use of it. If you're using a game that does not support hardware T&L with an Erazor X or any other GeForce, while things will be fast, they will not be as fast as they would be with hardware T&L support. If you would like a more in-depth look at NVIDIA's GeForce technology as well as hardware T&L, please read our GeForce Guide here. We also have a list of games that support hardware T&L here.
