NVIDIA: We've Had Sharpening in NVIDIA FreeStyle for Quite Some Time; Anti-Lag Sounds Like Maximum Pre-Rendered Frames Setting

During AMD's keynote at E3 2019, the 'Reddish Squad' announced more than only the next line of CPUs and GPUs. On the software side, they revealed a few technologies that are meant to meliorate graphics allegiance and input lag in games that implement them.

Radeon Image Sharpening (RIS) – Restores clarity to in-game images that have been softened past other mail service-procedure furnishings. RIS combines with GPU uspcaling to provide sharp visuals at fluid frame rates on very high-resolution displays and works across DirectX® ix, 12, and Vulkan® titles.
FidelityFX – An open-source developer toolkit available in the coming weeks on GPUOpen that makes it easier for developers to create loftier-quality post-processing effects that brand games look beautiful while offering a residue of visual fidelity and performance. FidelityFX features Dissimilarity-Adaptive Sharpening (CAS) that draws out item in low-contrast areas while minimizing artifacts acquired past typical epitome sharpening routines. Developers programme to integrate CAS into a number of popular games, and Unity Technologies plans to integrate it into its real-fourth dimension 3D development platform.
Radeon™ Anti-Lag – Optimized for eSports, Radeon™ Anti-Lag improves competitiveness past decreasing input-to-display response times by upwardly to 31 percent, delivering an experience similar to higher framerates.

The post-obit day, though, we attended a backside-closed-doors presentation with NVIDIA executives at the Courtyard past Marriott Hotel, just a short distance abroad from The Novo venue where AMD hosted its Next Horizon Gaming event.

The announcements shared by NVIDIA are still nether embargo, but we also had the chance to speak with Justin Walker, Manager of Product Management at NVIDIA, specifically about AMD'due south newly revealed technologies. On sharpening, he pointed out how NVIDIA Freestyle allowed gamers to tweak that e'er since it was introduced in early on 2018.

[...] they appear a bunch of technologies, Radeon Sharpening, which is fine. Only yous know, if yous want to go compare that we've got, we've had sharpening in NVIDIA Freestyle for a very long time. NVIDIA Freestyle has got a whole suite of filters, one of which is sharpening. But in that location's also things like HDR toning, and colour vibrance, all that stuff. Then if you lot want to play around with sharpening, just keep in mind, you lot don't have to wait.

That's not the only fashion PC gamers tin can do information technology, anyway. ReShade, the pop post-processing injector, also allows sharpening and many other like tweaks to graphics.

Moving on to the Anti-Lag subject, Walker had this to say:

I think it's something similar to what nosotros phone call maximum pre-rendered frames, which is actually something we've had in our control console for some time.

Basically what happens is during the graphics pipeline, the CPU will kickoff processing frames and transport them into the pipeline. Now, if you allow it to buffer frames, meaning to see if you lot just go as fast as y'all can even if the GPU is non ready, it may send a few frames in the pipeline. You practise that to get the max performance, then you can guarantee the GPU is never waiting for the CPU. Because if that happens, yous may accept to wait a footling for the CPU to process before it needs a GPU. So a lot of times, you'll buffer up a few frames in there, which is great if you're worried about just directly upwards operation. However, if you're sensitive to latency, which if you're an eSports fan you are, then whatsoever mouse movement you make will not affect frames already in that buffer. Then if I make a motion, it'll go into the next frame. Only that gets in line behind like a total frame already sitting there in the buffer. And and then that tin introduce, you know, depending on your frame rate, maybe 20 milliseconds of lag. Now, yous tin go to our control panel and set it yourself. And I think this is what they are doing, setting the maximum pre-rendered frames to one. And that won't do whatever buffering, which may affect your performance a picayune scrap, but it'll have your latency abroad.

It should be noted that Walker wasn't entirely sure AMD'south Radeon Anti-Lag engineering science was indeed based on this very concept. We'll take to wait for Anti-Lag to become available to detect whether this is actually the case.
