Strategic Objectives
• Master the mechanics of Asynchronous Timewarp (ATW) to stabilize frame rates.
• Implement advanced reprojection algorithms to compensate for dropped frames.
• Optimize the graphics pipeline for ultra-low latency environments.
• Understand the intersection of human perception and hardware performance.
The Core Challenge
In high-performance graphics, GPU lag creates a jarring disconnect that breaks immersion and causes motion sickness.
