AMD has recently unveiled FidelityFX SDK 2.0 alongside FSR 4.0.2, marking a significant leap in image upscaling capabilities through advanced AI acceleration technology. Nonetheless, in a rigorous test performed by @opinali utilizing the AMD FFX SDK 2.0 on the AMD Radeon RX 9070 XT graphics card, it was observed that while image quality witnessed an enhancement, frame rates took a hit. More precisely, under testing conditions where frame generation and vertical synchronization were disabled, the RX 9070 XT registered a frame rate of 276 FPS when FSR 4.0.2 was active, as opposed to 290 FPS achieved with FSR 3.1.5. This dip in performance can be attributed to FSR 4.0.2's employment of more sophisticated AI acceleration techniques, which, although enhancing image details, simultaneously elevates the demand on GPU computing resources.
