BOARD RULES

 No.644

Building a new PC
Can wait months/years
How much should I wait to buy a VR optimized GPU/CPU?

 No.645

Not sure what you mean by VR optimized.
It's more about the limits of today's technology and the rate of how fast data can be sent through HDMI and USB.

 No.646

honesty, build the best with your budget.
Only limit is your imagination. In all seriousness, try to get the best graphic card you can.

 No.647

You're going to need beefy hardware for VR, there will be optimizations of course, but there is only so much that can be done when you have two screens with both of them having a resolution at around 2K.

The good news is that you have a lot of time to decide since one way or another a PC VR headset is coming in winter. My suggestion is to wait for the current best GPU's to go down in price and then buy them.

Was waiting for a thread like this to pop up. I guess there are two types of PCs that can be built for VR, one that puts gaming and commercial applications at the forefront of what it is designed for and one for development and experimentation with homebrew and FLOSS.

I'm planning on building for the later once the Zen architecture from AMD comes out in late 2016 or early 2017. By then the major issues will have been ironed out with VR and several decent HMDs will be on the market. Prices for used GPUs with stable drivers will be low as well so having two of them won't be an issue.

Waiting up to two years is pretty extreme but I've never been an early adopter.

>>649
It's going to be a painful wait if you plan on waiting that long, the early stuff will be clunky yes, but it will be exciting talking with other VR users on what we find awesome.
But I guess ignorance is bliss in this case?

 No.651

>>650
I'm certainly going to keep an eye on what happens in VR and there's not going to be anything painful about it. I'm not jumping at new tech to fill a void in my life so I'd feel the same way if I had to wait another decade.

Again I consider my patience to be pretty extreme here. Most people will want to jump in as soon as possible and I'm glad that's the case, if everyone was like me this would go nowhere fast.

And to keep this on the topic of PC building this site is considered among the best when it comes to picking out parts.

I'm sure that if there's enough demand he'll add in a category for VR. The guy who made that site is an old /g/ tripfag and would be open to suggestions.

I would like to do that, but I really want something to play on.
I'm stuck with an online banned ps3, portables and a toaster.

I can try asking him on steam, will report any answer

Good luck, when is the steam starting?

Wait until the end of the year for the HTC Vive release.

Newer GPUs will be optimized for VR and it makes buying one now a pointless endeavour.

If this information about LiquidVR is to be believed it means that it'll run directly on the hardware mostly bypassing the OS, all positional tracking will be processed in GPU. Linux and BSD users will be able to enjoy VR meant for windows and developed using DirectX12 thanks to hardware-assisted virtualization, dual booting won't be necessary anymore.

With Android emulation it should be possible to try out Google Cardboard out as well but not Samsung Gear VR as Oculus doesn't support that feature:

From the news thread >>792

>In a post on the company’s official blog, Oculus recommends the following for the “full Rift experience” when the headset ships in Q1 2016:

NVIDIA GTX 970 / AMD 290 equivalent or greater

Intel i5-4590 equivalent or greater

8GB+ RAM

Compatible HDMI 1.3 video output

2x USB 3.0 ports

Windows 7 SP1 or newer

Still no word from Valve so these are the first minimum requirements presented. Don't go out and buy those GPUs right away as they're still in the $350-400 price range, when the HMDs come out you'll be able to buy much more powerful hardware at the same price.

The operating system requirement is quite a blow to Windows 8.1/10 and shouldn't surprise anyone paying attention to what's been happening between Microsoft and Facebook recently. W7 SP1 is almost 5 years old now and will really hamper the adoption of DX12 in VR when only a small portion of the userbase can use it.

>>651

I'm aiming for the first extremist build in this list, just with a single GTX980.

Is the difference that big with two cards instead of one?


 No.983

If you want to pay twice as much for a 20% increase in a best case scenario that's up to you to decide if the difference is worth it. I'd go with a single card for now but newer advances in linking GPUs together or sharing memory with the next generation of cards will make having several GPUs worth it compared to now.

This isn't the right time to buy if you're looking at building a computer for VR unless you can't help it, the graphic cards currently available are all very old or rebrands with more memory instead of new cards as shown by this picture for the recently released AMD cards. The fabrication process in the cards they change every few years and right now we're near the end of this generation. The 28nm GeForce 900 series has been around since 2014 with their new Pascal based cards coming out in 2016 and the 28nm AMD RX 200-300 series since 2013 with their new 400 series coming out in 2016 as well. Both these newer GPU series are going to have a 14-16nm fabrication process. That means in less than a year the card you'll have paid several hundred dollars for will have lost more than half its value as a new generation that will be around for 2-3 years starts selling.

And since no one has seemed to have gotten word from TheFalcon(owner of the logical increments site) I'll try contacting him this weekend to get a disclaimer or blog post on there about VR and how buying now is a bad idea and maybe what a computer devoted to VR should have for parts.

It took awhile but they've finally made a guide for VR gaming computers.

http://www.logicalincrements.com/articles/vrguide/

>First, an important note on multi-GPU systems: Support for rendering VR games with multiple GPUs is currently still under development. We believe that using multiple GPUs will be the best way to achieve high framerates and high graphical quality in future VR games. However, it may be some time before games are released with support for multi-GPU rendering. The first round of made-for-VR games on the horizon, such as EVE Valkyrie and Edge of Nowhere, will not take advantage of multiple GPUs, thus making virtually no difference in your performance whether you have two GPUs or one.

Even in the world of high performance computing the ability to use multiple GPUs(as with AMDs HSA) has only been added to compilers like the GCC very recently. It'll probably continue being a waste of money in 2016 for most consumers.
