Because VR is so demanding, hardware makers have difficulty ‘Recommended’ or ‘VR Ready’ tips to assist clients perceive what sort of hardware they want for a very good VR expertise. For probably the most half, the VR business’s largest gamers have agreed on the important thing elements of that advisable hardware. With the introduction of the Vive Pro, HTC is now suggesting the extra highly effective GTX 1070 as its ‘Recommended Spec’ for the Vive Pro, differing from the GTX 1060 instructed to be used with different main headsets.
Among other improvements, the Vive Pro brings a display with 78% extra pixels than the unique Vive (1,440 × 1,600 vs. 1,080 × 1,200, per eye), which signifies that, for a similar scene, a GPU powering the Vive Pro will want to do a non-trivial quantity of additional work to draw all of the pixels on the 90 FPS goal framerate; dropping under that focus on may cause visible artifacts and discomfort.
While HTC’s official Vive Pro page had initially listed the identical Recommended GPU as the unique Vive (the GTX 1060) to be used with the Vive Pro, at present the corporate up to date the web page to advocate NVIDIA’s GTX 1070, Quadro P5000, or AMD’s Radeon Vega 56. HTC tells Road to VR that the change was “based on NVIDIA’s testing.”
While the GTX 1070 or equal is now a part of the ‘Recommended Spec’, a brand new ‘Minimum Spec’ is listed, which nonetheless consists of the GTX 1060. Additionally, the Vive Pro’s ‘Minimum Spec’ differs from the unique Vive’s ‘Recommended Spec’ by requiring a USB three.zero port (as an alternative of two.zero), and dropping HDMI connectivity (now requiring DisplayPort 1.2 or newer).
The Vive Pro ‘Minimum Spec’ additionally not lists Windows 7, as an alternative now displaying Windows eight.1 or Windows 10. It’s not clear if meaning the Vive Pro merely gained’t work with Windows 7, or if HTC simply advises towards it, although we’ve reached out for affirmation.
While SteamVR’s new auto resolution function signifies that SteamVR content material ought to routinely adapt to the Vive Pro’s elevated rendering demand and permit the GPU to keep framerate, it might come on the expense of decreasing the rendering decision when the headset is used at the side of a GTX 1060-class GPU.
The transfer from GTX 1060 to 1070 because the headset’s ‘Recommended Spec’ isn’t a small change for shoppers, as present costs on the 1070 (~$625) are roughly twice as costly because the 1060 (~$325). Commercial customers, nevertheless, are much less doubtless to be impacted as they’re typically much less price-conscious and should already be utilizing higher-end hardware.
This change might be the beginning of a development of fragmentation among the many ‘VR Ready’ and ‘Recommended’ VR specs, which has been comparatively constant amongst main VR corporations to date, although we hope HTC and others will take steps to keep away from shopper confusion.
