The leap is significant and really hammers home the extra work the team have put in here to maximize the engine and capitalize on the gains that are possible when V-sync is no longer set to such a (relatively) low rate.
In a variety of tested sections, performance increased more around 50%, meaning frame-times are halved and input response increased – one of the biggest benefits of 120fps or faster framerates. The Performance Ray Tracing mode’s old 60fps limit is now doubled in the best of scenarios, though I only saw such a dramatic improvement briefly, when swinging across the city. The two other modes see much bigger leaps – and this is true across all three games (Spider-Man, Miles Morales, and Rift Apart). This helps reduce the judder when it falls outside of the VRR active range. Meaning when it drops into the 40s, it duplicates the frame 3x with the 8ms refresh. Insomniac does appear to be using a Low Framerate compensation, similar to a 2:3 Pulldown used in 24fps cinema modes on TVs. Those gains are respectable, but Fidelity mode is actually the least impressive here, compounded by the fact it is mostly outside of the useful range of VRR here. In 4K Fidelity mode, activating VRR results in performance gains of 12-13%, and as much as 25% in some cases, over the old 40fps limit. With VRR enabled this can extend beyond that, effectively unlocking the framerate to potentially reach that 120fps ceiling. Starting with Spider-Man Remastered, the game has been updated with a 120Hz mode – similar to what we received last year in Ratchet and Clank: Rift Apart – which boosts the 4K Fidelity mode to increase from 30fps up to 40fps due to it being a divisible rate of the 8ms frame time that 120Hz requires. Insomniac has leapt feet first into the VRR ring with not one but three updates which adds VRR to all 3 current modes, helped greatly by the single engine powering them all. On face value this sounds perfect, but some caveats come into the solution offered here. In other words, the removal of that 30 or 60fps cap while also eliminating screen tearing. The net result is the system can fluctuate between the 8ms ceiling of 120fps and down to 20.9ms or 48fps.

This means we can almost get the best of both worlds: the frame-time can change per frame and the TV will adjust its cycle within that defined window.

This technology enables the console or PC to “play the drum” instead, letting it tell the screen when to refresh for a new frame (within a defined scope) when it is ready. Until now this has been the dilemma: choose cleaner image quality at the cost of performance headroom or better performance at the cost of visual issues.Įnter VRR. The downside of turning off V-sync is that it can result in a torn image, where the screen has only part of the new frame at the bottom section, which is still being rendered by the PC/console, and part of the old one at the top. This is why turning off V-sync can sometimes improve performance, as it lets the system ignore this fixed period of waiting for the screen. The problem here, or at least one of a few, is this can come at a large cost to performance and impacts console and PC alike. This meant that game engines had to lock all their functions, loops and inputs into this fixed drumbeat that was dictated by the screen, called V-sync, and means that so long as both console and TV align at the same 16 or 33ms point in time, we get a new frame each time. The next rate below this is 30fps or 33ms, which divides into 60fps evenly. This means that the fastest a PC or console could send a new image would be every 16ms, which after 1 second gives us 60 new frames. Most popular TVs tended to be 60Hz, which is why 60fps has been the target for gaming performance for so long.

Prior to VRR (also known as Free-Sync/G-Sync), your TV or monitor fixed the rate at which games could update their images each frame, based on the speed at which the screen could refresh its display to draw a new image. VRR is a relatively new technology (2013) that changes a long-standing limitation of computer and console display methods.
