The quality of upscaling component in the FSR 2.2 implementation also comes with noticeable compromises in image quality and has several major instabilities: incomplete image details in the distance with constant flickering on thin objects in motion at lower resolutions, such as 1080p, ghosting and disocclusion artifacts around the main character or NPCs, a noticeable shimmering and flickering in motion on vegetation, power lines and thin still objects, and a blurry and incomplete look of most in-game particle and volumetric effects across all resolutions and quality modes. Compared to the DLAA solution, the anti-aliasing quality of FSR 2.2 is also inferior, as the overall image has more jagged lines in motion, especially visible on small particle effects during combat and in vegetation.
Speaking of DLAA and DLSS Super Resolution, the DLSS Super Resolution implementation offers the best image quality across all resolutions and quality modes when upscaling is enabled. Compared to the DLAA solution, with DLSS in "Quality" mode you can expect a sharp overall image with perfect stability on small particle and volumetric effects in motion, a stable image in motion with almost unnoticeable loss in rendering of the details on power lines, thin still objects, tree leaves and vegetation in general, and the absence of any form of shimmering or flickering artifacts. Surprisingly, compared to DLSS, the DLAA solution in Alan Wake 2 does not offer a significant boost in overall image quality across all resolutions, like it does in other games that we've tested, so in this game we recommend to stick to DLSS in "Quality" mode for the best image quality and performance.
The DLSS Frame Generation implementation in Alan Wake 2 is excellent, producing a stable and crisp image without any jittering issues on the in-game on-screen UI, the area where DLSS Frame Generation often has issues. Small particle effects, such as rain, are rendered correctly, even during fast movement. The hair rendering on the main character and NPCs also has perfect stability in motion. Also, the DLSS Frame Generation implementation in this game has the ability to use Frame Generation with DLAA. During our testing, overall gameplay felt very smooth and responsive, we haven't spotted any issues with input latency.
