Intel is bettering its body charge boosting expertise, XeSS, with a step ahead within the type of ExtraSS, which guarantees to maintain tempo with the most recent developments with Nvidia’s DLSS and AMD’s FSR.

As Wccftech noticed, at SIGGRAPH 2023 in Australia, Intel revealed it’s engaged on an extension to XeSS referred to as ExtraSS, which is a body technology characteristic to rival the efforts launched in DLSS Three and FSR 3.

The important thing distinction with Intel’s tackle body technology – which accurately refers to inserting further frames into the sport, to up the body charge and artificially make it smoother – makes use of body extrapolation.

That’s in distinction to AMD and Nvidia who each use body interpolation.

Intel explains: “We introduce ExtraSS, a novel framework that mixes spatial tremendous sampling and body extrapolation to reinforce real-time rendering efficiency. By integrating these methods, our strategy achieves a steadiness between efficiency and high quality, producing temporally secure and high-quality, high-resolution outcomes.”

Evaluation: Maintaining with the Joneses

This can be a essential step for Intel to maintain up with its GPU rivals. XeSS is a reasonably spectacular tackle body charge boosting general, however with body technology being the brand new king of upscaling city, Crew Blue would appear behind the instances if it didn’t have a look at its personal implementation. Enter ExtraSS (we’re not eager on the title, by the way).

As talked about, there’s a unique strategy for Intel going the extrapolation route, relatively than interpolation. What does this imply? As talked about, that is all about how the artificially inserted body is generated. With interpolation, it’s produced primarily based on the info of the 2 frames both aspect (earlier than and after). Nevertheless, with extrapolation, it’s primarily based on simply the one body.

To sum up in an admittedly crude nutshell, Intel ExtraSS solely makes use of one body and subsequently guesses extra concerning the make-up of the inserted body because of this, however the benefit is there’s no improve in enter lag (which is induced when drawing information from two frames, to make the body to insert in-between).

So, Intel scores with mitigating enter lag – which is the place AMD and Nvidia’s body technology applied sciences have confronted their strongest criticism – however at the price of the standard of the end result to some extent (extra guesswork is concerned), and risk of added artifacts and the like. Clearly, although, Intel will probably be working to maintain any of the latter right down to a minimal, and Crew Blue will need to hit a palatable steadiness between efficiency and high quality.

All that mentioned, whether or not extrapolating or interpolating, body technology remains to be a lot the identical tech at coronary heart, so Intel’s ExtraSS gained’t be all that completely different. It’s simply that Crew Blue will clearly be trying to get a slight leg-up on its rivals on the enter lag entrance. (Thoughts you, AMD and Nvidia do have their very own anti-lag options, as effectively, to fight any detrimental results of body technology – in supported situations, that’s).

In the end, the proof will probably be within the pudding, and we’re eager to see how Intel can work its magic within the body technology house when ExtraSS is definitely realized – although we don’t know when that’ll be.

ExtraSS could effectively take a while to return to fruition, actually if FSR Three is something to go by, which took a yr or so to reach (and additional time to iron out wrinkles, for that matter). In the meantime, Nvidia has pushed onto DLSS 3.5 with one other new spin on the upscaling tech, ray reconstruction – and it’s a critical step ahead. There’s no doubting who leads the fps boosting race, however AMD is making good progress with FSR Three of late, too.
