As of today if you order an HTC Vive VR Headset you should receive it mere days after you place your order, no longer is it a preorder process where you would need to wait an indeterminate amount of time.  The package will cost you  $799US or $1,149CAN so it is not quite an impulse buy but it certainly is very tempting.  You can order online or drop by a Microsoft Store, Gamestop or Micro Center if such things exist in your neighbourhood.  Al took a look at some of the technology in the Vive in this article, which is interesting to look at even if you can't quite afford one yet.

"HTC ViveTM can now be purchased through www.vive.com in 24 countries, shipping within 2-3 business days of purchase. In addition to online availability from HTC, individuals can now buy the revolutionary Vive virtual reality system in select Microsoft Stores, GameStop and Micro Center locations. Pre-orders placed through these retailers will be fulfilled beginning this week."

Introduction and Background

Introduction

VR is rapidly gaining steam lately with the recent launch of several capable platforms. I’ve briefly sampled the various iterations of development kits and pre-release units coming through our office, and understanding how they tracked the headset position was relatively easy. Then we got to play with an HTC Vive, and things got a bit more interesting. The Vive is a ‘whole room’ VR experience. You’re not sitting at a desk with a game controller. Instead, you are holding a pair of controllers that behave more like extensions of yourself (once you get used to them, that is). Making all of this work took some extra pieces included with the kit, and the electronics technician in me was dying to know just what made this thing tick. I’d imagine other readers of this site might feel the same, so I thought it appropriate to do some digging and report my findings here.

Before diving straight into the HTC Vive, a brief history lesson of game system positional tracking is in order.

160405-111847.jpg

I'll start with the Wii Remote controllers, which had a front mounted IR camera that ‘saw’ a pair of IR LED banks mounted in the ‘Sensor Bar’ – an ironic naming as the ‘sensor’ was actually in the Remotes. This setup lets you point a Wii Remote at the television and use it as a mouse. Due to the limited number of points in use, the system could not tell the Wii Remote location within the room. Instead, it could only get a vector relative to the Sensor Bar itself. Wii Remotes also contained accelerometers, but those were typically not used to assist in the accuracy of the pointing (but were used to determine if the remote was inverted, as the Sensor Bar had only two light sources).

160405-120039.jpg

The Oculus Rift was essentially a reversing of the technology used in the old Nintendo Wii Remotes. The headset position and orientation are determined by a desk-mounted IR camera which ‘looks’ at IR LEDs mounted to the headset. The system dubbed ‘Constellation’, can decode the pattern (seen faintly in the above photo) and determine the headset position and orientation in space.

160405-120435.jpg

Even the sides and rear of the headset have a specific LED pattern to help the camera lock on to someone looking away from it. If the IR camera sees the triangular pattern on the headset strap, it can conclude that the viewer us looking behind them.

The HTC Vive takes a different approach here. Since it was launching with a headset and two controllers that would all need to be tracked in space simultaneously. The Wii Remote style idea would only work with a much larger grid of sensor bars (or QR codes) peppered all over the room, so that idea was out. The Rift’s constellation system might have a hard time identifying unique light patterns on multiple devices that could be far away and possibly occluding each other. So if having cameras on the headset and controllers is out, and having a camera on the desk is out, what’s left?

Why things are different in VR performance testing

It has been an interesting past several weeks and I find myself in an interesting spot. Clearly, and without a shred of doubt, virtual reality, more than any other gaming platform that has come before it, needs an accurate measure of performance and experience. With traditional PC gaming, if you dropped a couple of frames, or saw a slightly out of sync animation, you might notice and get annoyed. But in VR, with a head-mounted display just inches from your face taking up your entire field of view, a hitch in frame or a stutter in motion can completely ruin the immersive experience that the game developer is aiming to provide. Even worse, it could cause dizziness, nausea and define your VR experience negatively, likely killing the excitement of the platform.

pic-hmd1.jpg

My conundrum, and the one that I think most of our industry rests in, is that we don’t yet have the tools and ability to properly quantify the performance of VR. In a market and a platform that so desperately needs to get this RIGHT, we are at a point where we are just trying to get it AT ALL. I have read and seen some other glances at performance of VR headsets like the Oculus Rift and the HTC Vive released today, but honest all are missing the mark at some level. Using tools built for traditional PC gaming environments just doesn’t work, and experiential reviews talk about what the gamer can expect to “feel” but lack the data and analysis to back it up and to help point the industry in the right direction to improve in the long run.

With final hardware from both Oculus and HTC / Valve in my hands for the last three weeks, I have, with the help of Ken and Allyn, been diving into the important question of HOW do we properly test VR? I will be upfront: we don’t have a final answer yet. But we have a direction. And we have some interesting results to show you that should prove we are on the right track. But we’ll need help from the likes of Valve, Oculus, AMD, NVIDIA, Intel and Microsoft to get it right. Based on a lot of discussion I’ve had in just the last 2-3 days, I think we are moving in the correct direction.

Why things are different in VR performance testing

So why don’t our existing tools work for testing performance in VR? Things like Fraps, Frame Rating and FCAT have revolutionized performance evaluation for PCs – so why not VR? The short answer is that the gaming pipeline changes in VR with the introduction of two new SDKs: Oculus and OpenVR.

Though both have differences, the key is that they are intercepting the draw ability from the GPU to the screen. When you attach an Oculus Rift or an HTC Vive to your PC it does not show up as a display in your system; this is a change from the first developer kits from Oculus years ago. Now they are driven by what’s known as “direct mode.” This mode offers improved user experiences and the ability for the Oculus an OpenVR systems to help with quite a bit of functionality for game developers. It also means there are actions being taken on the rendered frames after we can last monitor them. At least for today.

A system worthy of VR!

Early this year I started getting request after request for hardware suggestions for upcoming PC builds for VR. The excitement surrounding the Oculus Rift and the HTC Vive has caught fire across all spectrums of technology, from PC enthusiasts to gaming enthusiasts to just those of you interested in a technology that has been "right around the corner" for decades. The requests for build suggestions spanned our normal readership as well as those that had previously only focused on console gaming, and thus the need for a selection of build guides began.

Looking for all of the PC Perspective Spring 2016 VR guides?

I launched build guides for $900 and $1500 price points earlier in the week, but today we look at the flagship option, targeting a budget of $2500. Though this is a pricey system that should not be undertaken lightly, it is far from a "crazy expensive" build with multiple GPUs, multiple CPUs or high dollar items unnecessary for gaming and VR.

system1.jpg

With that in mind, let's jump right into the information you are looking for: the components we recommend.

VR Build Guide
$2500 Spring 2016
Component Amazon.com Link B&H Photo Link
Processor Intel Core i7-5930K $527 $578
Motherboard ASUS X99-A USB 3.1 $264 $259
Memory Corsair Dominator Platinum 16GB DDR4-3000 $169  
Graphics Card ASUS GeForce GTX 980 Ti STRIX $659 $669
Storage 512GB Samsung 950 Pro
Western Digital Red 4TB
$326
$180
$322
$154
Power Supply Corsair HX750i Platinum $144 $149
CPU Cooler Corsair H100i v2 $107 $107
Case Corsair Carbide 600C $149 $141
Total Price   Full cart - $2,519  

For those of you interested in a bit more detail on the why of the parts selection, rather than just the what, I have some additional information for you.

cpu.jpg

Unlike the previous two builds that used Intel's consumer Skylake processors, our $2500 build moves to the Haswell-E platform, an enthusiast design that comes from the realm of workstation products. The Core i7-5930K is a 6-core processor with HyperThreading, allowing for 12 addressable threads. Though we are targeting this machine for VR gaming, the move to this processor will mean better performance for other tasks as well including video encoding, photo editing and more. It's unlocked too - so if you want to stretch that clock speed up via overclocking, you have the flexibility for that.

Update: Several people have pointed out that the Core i7-5820K is a very similar processor to the 5930K, with a $100-150 price advantage. It's another great option if you are looking to save a bit more money, and you don't expect to want/need the additional PCI Express lanes the 5930K offers (40 lanes versus 28 lanes).

mb.jpg

With the transition to Haswell-E we have an ASUS X99-A USB 3.1 motherboard. This board is the first in our VR builds to support not just 2-Way SLI and CrossFire but 3-Way as well if we find that VR games and engines are able to consistently and properly integrate support for multi-GPU. This recently updated board from ASUS includes USB 3.1 support as you can tell from the name, includes 8 slots for DDR4 memory and offers enough PCIe lanes for expansion in all directions.

Looking to build a PC for the very first time, or need a refresher? You can find our recent step-by-step build videos to help you through the process right here!!

980ti.jpg

For our graphics card we have gone with the ASUS GeForce GTX 980 Ti Strix. The 980 Ti is the fastest single GPU solution on the market today and with 6GB of memory on-board should be able to handle anything that VR can toss at it. In terms of compute performance the 980 Ti is more than 40% faster than the GTX 980, the GPU used in our $1500 solution. The Strix integration uses a custom cooler that performs much better than the stock solution and is quieter.

More power for VR

Early this year I started getting request after request for hardware suggestions for upcoming PC builds for VR. The excitement surrounding the Oculus Rift and the HTC Vive has caught fire across all spectrums of technology, from PC enthusiasts to gaming enthusiasts to just those of you interested in a technology that has been "right around the corner" for decades. The requests for build suggestions spanned our normal readership as well as those that had previously only focused on console gaming, and thus the need for a selection of build guides began.

Looking for all of the PC Perspective Spring 2016 VR guides?

I have already given suggestions for a minimum specification build, with a target price of just $900, in a previous build guide. Today we are going to up the ante a bit more with some additional cash. What can we change and upgrade if given a budget of $1500 for a PC that will handle VR and standard PC gaming?

system.jpg

It turns out you can get quite a jump in performance with that added budget:

VR Build Guide
$1500 Spring 2016
Component Amazon.com Link B&H Photo Link
Processor Intel Core i7-6700K $362 $374
Motherboard MSI Z170A Gaming M5 $200 $183
Memory 16GB Corsair Vengeance LPX DDR4-3000 $79 $94

Power Supply Seasonic X650 Gold 650 watt $129  
CPU Cooler Cooler Master Hyper 212 EVO $29 $28
Case Fractal Design Define S Windowed $111  
Total Price   Full cart - $1,589  

For those of you interested in a bit more detail on the why of the parts selection, rather than just the what, I have some additional information for you.

cpu.jpg

The Core i7-6700K is the highest end consumer processor in Intel's lineup based on the Skylake architecture. This part is a quad-core CPU with HyperThreading enabled that allows for eight threads of processing at an extremely high base clock of 4.0 GHz. Even better, because of the K-designation, if you chose to venture into the world of overclocking, you'll be able to hit 4.5-4.7 GHz with little effort. The MSI Z170A Gaming M5 motherboard has all the overclocking features you'll need to get the job done while also including support for SLI and CrossFire multi-GPU setups, USB 3.1, dual M.2 storage connections and an improved audio interface. We were able to bump from 8GB to 16GB of DDR4 memory in this budget - a benefit for more than just gaming.

MSI is also the manufacturer of the NVIDIA GeForce GTX 980 graphics card we have selected, a a product that is easily the most important (and most expensive) component for your gaming and VR PC. With 4GB of GDDR5 memory, 2048 CUDA processing cores and the highest level of software and driver support for modern GPUs, the GTX 980 nets you anywhere from 15-25% additional performance over the GTX 970 from our $900 VR system build. For users considering an AMD option, the Radeon R9 390X and the Radeon R9 Nano are both fantastic options as well.
