NVIDIA is struggling with its DirectX 10 driver for its GeForce 8 series but already it has launched a demo to show what kind of effects the technology will bring. NVIDIA Cascades is the name of the demo and you have to have a copy of Windows Vista, 512MB RAM and a GeForce 8 graphics card with the ForceWare 100.64 drivers to playt the demo. Unfortunately I haven’t seen it person, but have had it confirmed by those that have tested NVIDIA’s new DX10 demo that it’s pretty impressive, which really gets our hopes up. Cascades can be downloaded from nZone.com where there is also a couple of screenshots for those who doesn’t have NVIDIA’s latest graphics card.
