For VR developers, keeping a high (90FPS+) and consistent frame rate is probably one of the biggest challenges they’ll face bringing games to market. In this session, Valve’s Alex Vlachos, Graphics Programmer, discusses techniques to adaptively alter your game’s fidelity in order to hit that FPS mark. Ben Lang is live-blogging this session, due to start @4PM PST.

Reliably hitting 90 fps in VR is a significant challenge. This talk will present a method for adaptively scaling fidelity to consistently maintain VR framerate without using reprojection techniques, even on very low-end GPUs, while also having the ability to increase fidelity for high-end GPUs and multi-GPU installations.

Speaker: Alex Vlachos, Graphics Programmer, Valve

Based in the UK, Paul has been immersed in interactive entertainment for the best part of 27 years and has followed advances in gaming with a passionate fervour. His obsession with graphical fidelity over the years has had him branded a ‘graphics whore’ (which he views as the highest compliment) more than once and he holds a particular candle for the dream of the ultimate immersive gaming experience. Having followed and been disappointed by the original VR explosion of the 90s, he then founded RiftVR.com to follow the new and exciting prospect of the rebirth of VR in products like the Oculus Rift. Paul joined forces with Ben to help build the new Road to VR in preparation for what he sees as VR’s coming of age over the next few years.

    Gamedevelopers have a seriously hard time getting SLI to work as-is. I doubt we’ll see proper working VR games, for multi-GPU setups, in the foreseeable future.
    Just look at the terrible implementation of SLI in The Division – it doesn’t work properly, with complaints all over The Internet about it.

    Fantastic coverage, I almost felt “presence” while reading ;)
    As a Unity user, that VR rendering plugin is a great news, Valve is pioneering again ! (btw, they fixed a competing engine and that fix works also with competing headsets. Not bad, not bad…)
