Esports players choose FidelityFX CAS over FSR 4 in Call of Duty Black Ops 7
AMD series graphics card users Radeon faced a discussion regarding the choice of the optimal image scaling mode in Call of Duty Black Ops 7. On the gaming platform Reddit, owners of modern graphics accelerators, including a system with a Ryzen 7 9700X processor and a video card Radeon RX The $800 9070 XT discussed the differences between AMD’s FSR 4 and FidelityFX CAS technologies. The main question is the feasibility of using full frame scaling versus a standard sharpening filter.
The majority of the community recommends using FSR 4 algorithms, as this version provides more advanced frame scaling mechanisms compared to FSR 3 and FSR 1. However, in esports shooters, scaling technologies can introduce additional input lag. Using FSR 4 in quality or balanced modes does not always guarantee a frame rate advantage over traditional image processing at native resolution.
Experienced gamers note that the FidelityFX CAS filter processes images at the native screen resolution without frame scaling, improving only the resulting sharpness. This approach ensures minimal input lag and a stable frame rate on powerful graphics cards. FSR 4’s superior frame rate is primarily evident in performance mode, where the final visual quality is noticeably reduced.
