The full release of the Resident Evil 4 remake has landed on PC, bringing nearly the exact same performance and graphical characteristics as the demo - for good and for ill. That means you can expect better-than-console performance and image quality, but there are still improvements for Capcom to make - and serious bugs you'll want to avoid. With that in mind, we'll focus our analysis on the optimised settings that'll help you get the most out of the game.
Let's start with the most important setting first: image upscaling. This is key as the game's temporal anti-aliasing (TAA) unfortunately doesn't produce great results, while an enforced sharpening filter tends to degrade the image further. Even with a static camera, you'll notice that vegetation crawls, edges shimmer incessantly and the whole scene has a posterised look.
Normally we'd look to the likes of DLSS, XeSS or FSR2 to solve these problems, but while FSR2 is available it doesn't look right. The presentation with FSR2 enabled is overly soft, shimmery and some areas are visibly aliased. We'd only really recommend it at 4K, where the base resolution is sufficient to produce a reasonable result. FSR1 is available too, but it's even worse, as it compounds the image quality issues by sharpening and upscaling an already oversharpened and poorly aliased image.
