This FSR 4 review shows tons of side by sides vs FSR 3.1, DLSS 3, and DLSS 4 at 1080p, 1440p, and 4K resolutions. I also look at the performance of FSR 4 vs FSR 3.1, and discuss supported games. All video capture was done using an HDMI capture card on a second PC. Note that DLSS 4 was implemented via DLSS Swapper and based on the footage it does not look like the correct preset was applied. I have used the YouTube "Trim" feature to delete these sections of the video. All other comparisons are good. The FSR footage, and Native TAA footage was captured using an RX 9070 XT. The DLSS 3 and 4 footage was captured using an RTX 5070.
