The SteamDevDays developer only conference continues today, and as press aren't permitted at the event, we're once again fishing details of the various presentations from social media reports of attending game developers. Fortunately, developers such as Hot Blooded Games' Dave Oshry are sharing a lot, so we have a bunch of new details from today's Virtual Reality-related presentations.According to Oshry's Twitter stream , Oculus founder Palmer Luckey "says Valve's VR tech is the best virtual reality demo in the world right now", which gels with what Tripwire Interactive's David Hensley Tweeted yesterday about his experience with Valve's on-site demo, describing it as "a lucid dream state and very much like a holodeck" ( source ), "like playing an XBOX compared to the Oculus's "8bit Nintendo" ( source ), suggesting that it had both a higher screen resolution and lower motion-to-last-photon latency.Valve still does not seem to have confirmed whether it has any ambitions to market its own VR hardware, but the level of cooperation with Oculus (it has been confirmed that Valve and Oculus collaborated on positional tracking tech), suggests that Valve's own prototyping has been primarily serving more as a testing aparatus for its software development aimed at making Steam the go-to platform for game developers boarding the VR train.A slide posted by Oshry on Twitter from the presentation by Valve's Michael Abrash posits that Valve and Oculus expect the following to be possible with consumer VR hardware by 2015:Gaming's VR future might not be too far away.As with yesterday's sessions, the folks at SteamDB are doing a fantastic job of collating details from various developer tweets. Valve has also reiterated that it intends to publish video recordings of the presentations sometime in the future.
