Sony’s adding system-wide supersampling to the PlayStation 4 Pro as part of the in-beta firmware update v5.50, and that means Digital Foundry’s already whipped out its pixel counters and magnifying glasses in order to confirm that the enforced antialiasing is doing its job. A new article on Eurogamer.net reveals that the feature is offering up some nifty improvements to titles that don’t natively downsample, with a reduction of jaggies being the most notable improvement.
For those of you who don’t know what supersampling is, it’s essentially the act of taking an image rendered at a higher resolution and scaling it back down to 1080p. This means you end up with better picture quality, and while most PS4 Pro titles support the feature natively, there are a handful like The Last Guardian and Metal Gear Solid V: The Phantom Pain that don’t.
Now the functionality’s not perfect. For starters, games like The Last Guardian actually perform worse in 4K than at 1080p on the PS4 Pro, therefore if you opt to supersample you’re stuck with an impacted framerate in exchange for better image quality. Also, you can get some blurring on assets designed for Ultra HD screens when they’re scaled down. The feature’s totally optional, though, and can be toggled on and off, so while it’s not the most elegant solution, it’s getting the job done.
