Optimized graphics settings for the Assassin's Creed Black Flag resync

The Assassin's Creed Black Flag resync features significant visual upgrades, including ray tracing by default, but requires manual configuration to address issues with upscaling and performance. The game's upscaling implementation is currently flawed, as it defaults to an outdated DLSS 3 model across most settings. Users can manually correct this by forcing the game to use DLSS 4.5 via the NVIDIA app, which improves visual quality and sharpness. However, this fix comes at a performance cost compared to the game's native upscaling implementation. Additionally, the game's upscaling modes, including DLSS, FSR, and XeSS, utilize incorrect output resolution scales when set to balanced or performance modes. This results in a blurrier image, which can be mitigated by setting the upscaling mode to custom and manually adjusting the resolution scale to 100%. While the game is well-optimized, these manual adjustments are necessary to achieve the best balance of visual fidelity and performance, particularly on lower-end hardware.

The game's default upscaling implementation uses an outdated DLSS 3 model, which can be improved by manually overriding it to DLSS 4.5. Upscaling modes like DLSS, FSR, and XeSS incorrectly set the output resolution scale to less than 100% in balanced and performance modes.

Manually setting the upscaling mode to custom and the resolution scale to 100% fixes the blurriness caused by incorrect output scaling. Shadow quality is the most performance-intensive setting, with higher options providing more detailed shadows and better soft shadowing.

Ray tracing, while demanding, significantly improves water reflections and should be kept enabled on the extended mode for the best visual quality. The texture resolution quality setting has no impact on performance if sufficient VRAM is available, so it should be set to the highest level possible.
