What specific combination of hardware and Zwift graphics settings would be required to achieve a consistently smooth 60 FPS at 1440p resolution with all graphical features enabled, without resorting to pixelation or decreased draw distance, and how would these settings impact performance on lower-end hardware configurations? Additionally, what metrics or tools can be used to benchmark Zwifts graphics performance and identify bottlenecks or inefficiencies in the rendering pipeline, and how can these be used to inform and optimize Zwifts graphics settings for a wide range of hardware configurations, from budget-friendly options to high-end gaming PCs?
