Phoronix: Unigine Takes Advantage Of OpenGL 4.0
It was just shy of a month ago when Unigine Heaven 2.0 was released with Linux support and it showed what Linux gaming can look like while slaughtering your graphics card. Unigine Corp, the company responsible for this multi-platform game engine, though hasn't been sitting around idly since the Heaven 2.0 release, but they have in fact been moving forward with great improvements their game engine...

Well i really like to see that new engine in action. Particually i want to know if the OpenGL 4 tesselation is faster than the AMD_vertex_shader_tessellator. That was extremly slow. In some DX11 unigine heaven comparisons the nvidia gtx 470/480 was really shining with tesselation compared to ati hd 5850/5870. Now i want to see Linux results...
Well well well.. It will be an interesting benchmark: DX11 Tesselation vs OGL4 tesselation.. Linux OGL4 vs Win7 OGL4 etc.
Well that's mainly because HD58xx has only one tessellator and GTX470/480 has like 12 of them ? or 16. Don't remember the exact number but it's something like this. I'm not really a fanboy of ATI or NVIDIA, but I just think that increasing those tessellation units would greatly help ATI here![]()
No, ATI is using a piece of fixed-function hardware to do the tesselation while NVidia is hooking it straight into the programmable shader hardware. NVidia's technique is probably the superior one, it's definitely better in their high end cards. I would expect the low-end ATI cards to blow away low end Fermi's, though, since they wouldn't scale performance down like the nvidia cards would. Well, when they actually exist that is - right now nvidia only supports tesselation in the very top of their high-end cards.
