Nvidia GeForce RTX Brings Groundbreaking Ray Tracing, but Should Gamers Care Right Now?

Nvidia began the week with a bang, announcing their all-new GeForce RTX GPUs, namely the RTX 2070, 2080, and the 2080 Ti, based on the groundbreaking Turing compages. Apart from the CUDA cores and the new GDDR6 retentivity, what's actually impressive about these new graphics cards is the fact that they bring existent-time ray tracing to games, past doing the heavy lifting for developers in dynamic lighting and shadow furnishings.

Just is it really that big a deal for gamers right at present? From what we saw the Gamescom 2018, it isn't. Or rather it won't be for some time.

Mail service the Nvidia event, we played some of the titles making use of this applied science. We played Metro Exodus, Shadow of the Tomb Raider, and Battlefield Five, and truth exist told, while there is potential, the gaming experience in itself left a lot to be desired.

Let's talk almost positives start. Ray tracing essentially affects the overall lighting in every frame of the games, and information technology clearly shows. The overall lighting of each environment is based on accurate light reflection and interaction with objects in the scene. Merely, the question is, does ray tracing make that much of a difference at the moment? Well, at its electric current bespeak, it faces a lot of bug. Let's dig into them:

Long Development Process

When we spoke to the Metro Exodus team at Gamescom 2018, we got the impression that yes, ray tracing has its advantages. Similar nosotros said it does all the heavy lifting for devs: instead of assigning low-cal backdrop for each visual element along with a carve up shadow, all developers now need to do is merely design the elements and add specific characteristics nigh the opacity, reflection, and that's pretty much it. Ray tracing should have care of the residue. This should allow them to focus on other important parts of the game, while ray tracing helps brand visuals more life-like. While it sounds easy, nosotros were told, information technology's not that elementary.

One major event is that RTX is all the same pretty new. Like literally new. While the games showcased at Gamescom had early access to it, there is no way that they would take mastered information technology in such short time. Adapting to the new technology is time-consuming as devs accept to get familiar with the framework, the new APIs, the new engines, and what non. In fact, in conversation, Metro Exodus devs told united states it would accept more than a twelvemonth for well-nigh developers to understand RTX and implement information technology to its total potential.

To bring ray tracing to their games developer teams would have to put in twice the corporeality of work – you still have to ensure compatibility with older GPUs, and ensure the game is up to scratch for RTX tech.

Backwards Compatibility

Nvidia showed a demo which highlighted the 6x better ray-tracing performance in the new Turing GPUs every bit compared to the older Pascal GPUs. That's a massive crash-land for sure, but last-gen cards and older GPUs are withal quite powerful.

There are even so gamers rocking DDR3 RAM along with a Nvidia GTX 780 Ti and are gaming at 144Hz with no problems. A lot of people are using the 9xx and the 10xx series GPUs, without issues. These are pretty capable systems and can practically handle a lot of load, except ray tracing, evidently.

Performance Takes A Hit

And allow'southward face up it, how many people are actually going to exist ownership the new RTX GPUs right now? The main advantages that the RTX GPUs bring are tied to developers actually adopting the technology, and they'd only do that one time RTX becomes a mainstream thing. Unfortunately, that is still at least a year abroad.

The 6X performance is only on ray tracing metrics, and not the overall performance. Equally for everything else, the updates are incremental, so with RTX off, you are likely to see an improvement of just around eight-x FPS.

Ray Tracing vs Gameplay

Then I did just claim that if you don't want ray tracing right at present, the electric current-gen GTX GPUs should hold up pretty well, simply you might wonder why one wouldn't want to live on the bleeding edge of technology with the RTX GPUs. Well, this brings me to my favorite part of this give-and-take, which is the actual gameplay.

Metro Exodus

Allow's start with Metro Exodus. The Metro series has been a benchmark game in terms of visuals and authentic setting, and Exodus is no unlike.

I could easily see that while the game definitely looks meliorate with RTX toggled on. Ray tracing makes the game look stunning, equally y'all tin come across in the video in a higher place, which highlights portions of the game that ray tracing has added its magic to. But on the other hand the the performance suffers and you lot could come across some frame drops.  The developers admitted that this is simply because RTX is even so a new technology, and they still have to devote a lot of more time to really make the game stable.

"FPS has never been our main focus with Metro; it's more about the graphics quality. However, stability is a business concern, and that is something nosotros definitely need to work a lot on right now, especially with RTX hither," said ane Metro Exodus developer we met here.

Shadow of the Tomb Raider

Metro Exodus isn't due out till at to the lowest degree half dozen months, and so the devs still have time to iron out the issues. That's non the case with Shadow of the Tomb Raider, which is due for release in September. With RTX on, the game performs really bad, and information technology almost feels like you're playing an alpha build of the game, which really shouldn't be the case so shut to the release.

Again, the visuals are simply stunning, which you can see in the clip above – we beloved the shadows and light play in the ambient lighting of this scene.

That being said, the performance drops weren't every bit bad as Metro Exodus, and certainly, not equally bad equally Battleground V.

Battlefield Five

Okay, so DICE and EA have had their fair share of bad and buggy launches, and it seems similar Battlefield V is headed in the aforementioned direction. I was trying out their new City map in the multiplayer mode, and it's a hot mess. The Battlefield V systems had GeForce Experience, so I had access to the FPS meter too, which fabricated things worse.

For a game called Battlefield, you are bound to accept standard explosions and smoke elements in the game. The game averages at 88 FPS for well-nigh scenes, which is pretty good. However, the moment there is an explosion in the game, the count drops massively, to a low of 33 FPS, which is just disappointing. Frame drops at explosions is to expected, but with RTX, the organisation is processing a lot of data in real-time, and information technology just really hampers the performance. This will of course be fine-tuned as developers get more familiar with this applied science.

Ray Tracing in eSports and Multiplayer

So beingness the critic I am, I spent the beginning 5-7 minutes of Battlefield V, inspecting the touch of RTX on each and every element in the game, and honestly, it all looked pretty and gorgeous. But here's the thing. Once I actually played the game, I hardly noticed these visual improvements, except for when the frames dropped.

Games such as Battleground, Call of Duty, Counter-Strike, and other eSports titles are unremarkably quite fast-paced. Players may care almost visual fidelity here, but you'd hardly find them pushing things to the max. In fact, nearly eSports players actually melody down the settings to get amend FPS. With RTX On, you become those crawly visuals, but the performance could take a major hit.

Be it Battlefield 3, Battlefield four, Battleground one, or the upcoming Battlefield V, (yep, that's the society the games accept been released in), the multiplayer segment has pretty much looked the same. This is near apparent when you lot look at the gameplay videos, or amend yet, play the mode. Gamers of these titles demand better mechanics, better weapons, meliorate movements, more physics. Enhanced visuals is probably depression on their list of demands, but ray tracing delivers that; now it'due south up to the developers to optimize information technology and then that operation is not impacted.

The Console Dilemma

Yes, single player games would definitely benefit from RTX, provided that they're able to overcome the hassles we've already gone over. Simply, unmarried actor games also face another issue, which many of you might take missed spotting.

For titles that are first developed for consoles and so ported to PC, which allow's face it is almost titles, GeForce RTX is some other development track. Both the Xbox and PS4 use AMD GPUs, which currently practice not support ray tracing like Nvidia's RTX tech. As such, porting a console game to PC and adding RTX to introduces a lot of development complication. As such, the overall library of games that will have support for Nvidia's RTX is already looking quite minor.

And that'due south not virtually to alter any time soon. Nosotros don't know when the next generation of PlayStation and Xbox would be released, just it has already been confirmed that they would both use AMD GPUs again. And while the newer AMD Chipsets would feature ray tracing enhancements themselves, information technology is, in one case once more, more than a year away, and comes with its own development challenges.

Should Yous Purchase GeForce RTX Now?

There's niggling doubt that ray tracing as washed by the Nvidia RTX is a staggering piece of technology which takes game visuals to the side by side level. But information technology must be noted that Nvidia has simply but introduced the technology. Its real benefit would simply be seen when developers actually make use of information technology, which seems at least about 12-18 months away. The new RTX GPUs bring something groundbreaking to the tabular array, but it'southward gonna be a while till developers perfect its implementation.

Then as a gamer looking to build a halfway powerful gaming PC, should y'all be considering the new RTX GPUs right at present? It'southward a dilemma for sure, but one made easy by the fact that if you were looking to get a GTX 1080 right now, information technology might be better to wait till the RTX 2070 is out, given that the RTX card is probable to be on par in terms of performance on most metrics. Given that the GTX 1080 and the RTX 2070 are roughly effectually the same toll, you might desire to expect for the latter to get those sweet visuals.
