DirectX 10 Preview: The Future of PC Graphics and Gaming
FiringSquad: A lot has been made about the speed boost DirectX 10 will bring over DX9. In part due to the new driver model and in part due to other efficiencies. In your position you get to work with the latest hardware – can you tell us without violating any NDAs if these speedups are realistic or not? Will we really see a 6X increase in games or is this all theoretical?
Tim Sweeney: We don't have hard data yet, but it looks like there's potential to reduce the CPU cost of submitting rendering by a factor of 2-4. Since DirectX9 games are often CPU-limited, this should lead to significant visible improvements in frame rate.
