AMD’s latest FidelityFX Super Resolution (FSR) update might look like a routine maintenance patch, but under the hood, it’s setting the stage for one of the company’s most ambitious upgrades yet. FSR 3.1.4, released this week, folds in fixes to AMD’s temporal upscaler while quietly wiring in support for the upcoming “Redstone” suite of AI-driven rendering technologies that are due later this year.
The most immediate change is a reduction in ghosting on newly disoccluded pixels, or previously hidden ones that suddenly come into view. That's a problem that’s long plagued FSR in fast camera pans and dense environments. AMD says the new approach should produce cleaner, sharper images when objects move quickly or the viewpoint shifts abruptly. Alongside that comes a signed, easily upgradable DLL, part of the “FSR 4 driver upgrade” system, which should make future updates far less painful for developers already shipping FSR 3.
