How did Hardware Unboxed measure FSR 4 frame pacing issues in their tests?
Hardware Unboxed measured FSR 4 frame pacing issues by benchmarking frame generation using slow-motion cameras to observe how long generated frames were actually displayed on screen. Their slow-motion footage showed the RX 9070 XT often displaying one frame roughly four times longer than the next, producing severe visible jittering, and they also tested with V-Sync enabled and found the same issues.
