Ray tracing is changing into extra commonplace as time goes on, with high-end GPUs and the next-gen PS5 and Xbox Series X consoles boasting this premium function. However what’s ray tracing, and the way can it influence your sport’s efficiency?

On this information, we’re going to run by way of what ray tracing is and why it’s vital, in addition to the way it can have an effect on the standard of video video games. And for those who occur to personal the suitable {hardware}, we’re going to clarify how one can get this function up and working, and what video games truly help the software program.

So, with out losing any extra time, right here is every little thing you have to find out about ray tracing.

What’s ray tracing?

Ray tracing is a way that helps make video games extra life like, because it higher emulates the best way that mild displays and interacts in the actual world, thus making video games extra immersive.

It really works by simulating actual mild rays and utilizing an algorithm to hint the trail that precise mild would soak up the actual world, which permits builders to higher simulate how mild bounces off objects and create life like shadows. This ends in extra life like scenes general, with characters and NPCs interacting extra naturally with the world.

What GPUs help ray tracing?

Whereas we all know that each new consoles have help for ray tracing, there are a number of choices relating to your GPU. The Nvidia RTX 3050 presents help for ray tracing at a less expensive value than ever earlier than, permitting avid gamers to expertise ray tracing at 1080p. It additionally has help for DLSS, which is an Nvidia RTX function that makes use of synthetic intelligence to spice up a sport’s framerate.

The Ampere technology of ray tracing playing cards contains the RTX 3000 collection, which is made up of the RTX 3060, RTX 3060 Ti, RTX 3070, RTX 3070 Ti, RTX 3080, RTX 3080 Ti and the RTX 3090.

The RTX GPUs function {hardware} known as Tensor Cores and RT Cores, that are wanted to make real-time ray tracing work as effectively as attainable. Nvidia additionally invited the time period ‘Giga Rays’, which refers to how profitable the racy tracing efficiency of the GPU is.

Nvidia claims that 5 Giga Rays per second is the minimal quantity of digital mild ideally required to totally illuminate a typical room in a online game surroundings. The RTX 2070 presents the usual 5 Giga Rays per second, however for those who improve to 2080, it presents eight Giga Rays per second, with the 2080 Ti capping out at 10 Giga Rays per second.

Nevertheless, Nvidia is about to announce a number of new GPUs throughout its newest September GTC 2022 Keynote occasion, which is able to take over from the RTX 3000 collection. The newest collection would be the Nvidia RTX 4000, codenamed Lovelace, which is anticipated to incorporate the RTX 4070, RTX 4080 and RTX 4090.

Whereas nothing has been confirmed but, we predict the Lovelace GPUs to have ray tracing capabilities, since they’re anticipated to pack a 5nm node in comparison with its predecessor’s 8nm node, permitting the corporate to incorporate much more transistors which ought to guarantee higher efficiency.

We are going to you’ll want to replace you on the ray tracing capabilities of the Nvidia RTX 4000 collection when they’re introduced, however we’d anticipate that the efficiency will outpace the RTX 3000 collection, which ought to enable them to offer a smoother expertise for avid gamers who wish to use ray tracing whereas gaming.

AMD additionally presents up ray tracing options, with the AMD Radeon 6000 collection being the model’s first try at implementing the expertise. The corporate is just a little additional behind when in comparison with Nvidia, seeing because the GPUs are nonetheless of their first technology.

Yow will discover ray tracing help in a number of AMD playing cards, although not as many as Nvidia, together with the RX 6600 XT, RX 6700 XT, RX 6800, RX 6800 XT and RX 6900 XT.

Not like Nvidia, AMD doesn’t have a devoted set of {hardware} cores, as an alternative, AMD GPUs use {hardware} cores that deal with the ray tracing whereas additionally performing different capabilities on the identical time; AMD refers to those as Ray Accelerators.

The corporate additionally has an answer to Nvidia’s DLSS: FSR 2.0. That is the second technology of FSR and will assist bridge the hole between Nvidia and AMD since Nvidia has traditionally received out by way of picture high quality because it makes use of machine studying to reinforce its visuals.

Plus, Sony is now working on accelerated ray tracing, which is able to take away strain from its graphics chip within the PS5 whereas additionally decreasing the rendering time on shaded visuals. This might enable for ray tracing to be turned on with out compromising the body price or the highest answer, which must also allow extra video games to utilise the function.

Is ray tracing price it?

Ray tracing has come a good distance because it first launched in Battlefield 5, with a number of video games now supporting the expertise. Ray tracing did actually excel on this sport, with mountain ranges being seen within the reflection of the frozen lake and flames glinting off the metallic surfaces of the weapons.

Seeing as GPUs that boast the expertise are getting cheaper and extra plentiful, and next-generation consoles are making ray tracing extra accessible and fewer demanding, it appears that evidently inside the subsequent few years ray tracing might be accessible to most avid gamers.

Whereas the extent of element that ray tracing brings is spectacular, additionally it is not important for each sport. The makers of Forza Horizon 5 particularly only implemented ray tracing in one section of the game, claiming that the advantage of ray tracing can be misplaced throughout the racing sections of the sport and it might truly hinder the standard of the visuals general.

The worthwhileness of ray tracing will depend on each the setup you might have and what sport you’re planning on enjoying. When you have a high-end GPU that received’t battle successfully implementing ray tracing, you doubtless received’t see different elements of your sport falter as outcome. And a sport like Minecraft, which already doesn’t put a lot strain on a GPU, can efficiently utilise ray tracing to create extra life like lighting results and considerably enhance the visuals, all whereas being noticeable to the buyer.

The PS5 and Xbox Sequence X supply dependable options for ray tracing since each consoles do usually prioritise stability over excessive efficiency whereas nonetheless giving the choice for ray tracing in sure video games.

We’d counsel that any avid gamers who’re inquisitive about ray tracing take a look at their very own internals and see if their present set-up is viable, particularly if they’re fascinated about a title that already helps ray tracing and received’t put an excessive amount of pressure on their PC. For anybody else who’s however is not sure about taking a look at GPUs, each the next-generation Sony and Microsoft consoles are reliable gadgets that provide ray tracing throughout a number of video games.

Which video games help ray tracing?

Extra video games than ever now help ray tracing expertise, with each AMD and Nvidia having options in addition to mainstream consoles. Not each PC or console sport will help the expertise although, with some video games additionally solely permitting the function in sure modes or sections of a sport.

The checklist of PC video games that help ray tracing is as follows:

Whereas this isn’t a conclusive checklist of all of the PC video games that help ray tracing, the quantity is excessive and nonetheless rising, which can be sufficient of an incentive for some avid gamers to take the leap and buy a GPU able to ray tracing.

For console avid gamers, right here is the checklist of all of the PS5 video games that help ray tracing:

And listed below are all of the Xbox Sequence X video games:
