Whoever is in charge over there has their head lodged somewhere smelly.
It might come as a shock to Phoronix folks, but Unigine really is practically unheard of in the industry. There are essentially zero developers with experience in Unigine, zero artists and content folks with experience in Unigine, and zero publishers debating whether a Unigine license will cut costs. On the other hand, as much of a pile of crap as it is, there are thousands of devs, artists, and publishers with extensive experience with UDK. There is also a quickly increasing number of people with Unity experience due it being so reasonably priced (less than one week's pay per developer to get an entire commercial-grade engine with content pipeline) and easy to use.
Also, I'm working on a theory that Unity's Asset Store is its largest success: many people using Unity are writing addons for it and blogging about them and trying to get everyone else to use Unity just because it means more addon sales and a strong network effect occurs. Developers using UDK or Unigine or CryTek or whatever have no real reason to spend lots of time and energy trying to convince everyone else to also jump on the same bandwagon. The market for game engines is small, its almost exclusively nerdy tech types, and that kind of word-of-mouth community energy really matters in those circles, much more than it does for general mass-market products. Some kind of community-focused content/plugin system for Unigine (or any other engine) is something engine developers should consider very strongly.
The tesselation in those rocks is very subtle, and completely doable in proper art without. No that pic doesn't convince to get a gl4 card
Most time you won't notice the difference because you are to far away.
OK. I haven't played with tessellation yet because my card can't do that.
But as I played through the game most time I didn't zoom in because then I would miss what is going on around.
Some kind of first person game would have been better to demonstrate ultra graphics quality.
Oil Rush looks nice.
But also it doesn't have much to show.
Most time water, some rocks and ice and buildings.
But nothing that would bring people to OpenGL4.
(It would be nice if someone could do a little comparison of Oil Rush on OpenGL 3 vs. 4 (maybe even throw dx9 and dx11 in) and see if there is anything different.)
