VR is 7 times more demanding of your PC than 1080p gaming, say NVIDIA

NVIDIA VR 7 times more powerful

Anticipation is slowly turning into reality in the virtual reality market, with Oculus recently announcing iminent preorder availability of their head-mounted displays. But there's still so much uncertainty about it all, isn't there? We don't know how much the hardware will cost or when it'll be released, and we're only now getting an idea of the PC specs requires to run a smooth VR experience.

On that front, the forecast from NVIDIA is quite dramatic - you'll need seven times the performance required to run current games at 1080p and 30 fps.

Both Elite: Dangerous and EVE: Valkyrie are at the forefront of VR - and they're among the best space games on PC.

Jason Paul, general manager of Nvidia's Shield, gaming, and VR business, recently spoke to VentureBeat about the increased demands VR puts on your system, and NVIDIA's CES 2016 keynote made the case that "immersive VR experiences are 7x more demanding than PC gaming."

That's based on the assumption that PC gaming equals 1080p and 30 fps (far from a unified standard), compared to two separate displays, each at 1680 x 1512 (a total output resolution of 3024 x 1680), running at 90 fps.

Paul told VentureBeat: ""We see the potential of VR as very large, but we also see a big challenge as far as the computing power that's required."

"If you look at your typical PC gaming experience, 90 per cent of the gamers out there play at 1080p. For a smooth experience you don't want to go below 30fps. Compare that to VR where the displays are about 2K, but you have to render closer to 3K, and you don't want to go below 90fps.

"It's about a sevenfold increase in raw performance to render for VR versus traditional PC gaming. You have to do that in less than 20 milliseconds from head rotation to what shows up on your display."

By the company's own estimations, around 13 million machines worldwide are currently capable of running VR applications at those output levels. They also claim that number could be increased to 25 million by developers and gamers using NVIDIA's own Designworks VR and Gameworks VR software. 

Gameworks alone provides up to a 50% performance increase, they claim.

However, that sevenfold increase in system requirements stated by NVIDIA hasn't been seconded by VR game developers themselves - Elite: Dangerous's own recommended specs require a GTX 980 and Intel Core i7-3770K for VR, which is hefty but reasonable.

If that 700% performance increase really is required, it's certainly going to hobble VR's widespread adoption. We don't know how much the headsets themselves will cost, but the added expense of building a super high-end gaming PC is going to put a lot of people off.

What a load of nonsense. 7 times? Complete rubbish!

sounds like an attempt to sell a load of hardware people don't need to me. and if anyone can point me to a single instance when gameworks improved performance I'll be amazed!

That's quite daunting. My pc runs virtually any game at 60 fps but I would have to get a new one to get that kind of increase in performance I think. A pc of that spec would probably cost about 5 or maybe even 6 times as much as a console on the low end.

You could build a pc to Frontiers requirements for 4 times the cost of a console, probably even 3x if you didn't care about pushing future proof (Skylake) and are willing to wait for a Pascal gpu

All posts were towards the GTX970 being the foundation of VR gaming (including nvidea) but frontier have to push that... Guess I'll be upgrading to Pascal next year, assuming this is more than a sales pitch.

Why don't you want it dipping down below 90FPS? 60FPS is the limit that the natural human eye can see. Anything below THAT would seem unimmersive.

This is PR BS. VR will not be for low-mid range rigs but anyone with am enthusiast grade PC can run VR.
