This year Epic released a video demonstrating what is Unreal Engine 3 capable of.Showing what's gonna bring DirectX 11 to the table.The problem is that they were running using 3 Nvidia GTX 580 cards.If we take the price of the cheapest which is 489$.It's gonna cost 1467$,only the video cards and we're not counting the CPU,RAM and Motherboard.Well, i forgot to mention about the power supply,i think at least you'll need 1.5kW power supply and it will cost you 1000$ and the other thing is i don't know if they were running on a workstation,if that's so then the only thing i can say is "Oh crap".
What's all the fuzz about DirectX 11?
In my opinion DirectX is all about tessellation.Real time displacement mapping,more detail for gamers.
Unfortunately there are not that many games that use DirectX 11 or i should say too few actually.Just head http://en.wikipedia.org/wiki/List_of_games_with_DirectX_11_support and you'll see.Just to notice any difference you'll need a microscope.If you look back at 2005 when Splinter Cell Chaos theory came out,it was one of the first games that supported DirectX 9.0c or Shader Model 3 and let's look at Crysis 2.
They're both based on DirectX 9.0c.
Battlefield 3 is one of the first games that's gonna be DirectX 11 focused and it won't run on Windows XP,that's what DICE is saying.
Now imagine few years later after Battlefield 3 is released.Games are gonna look better,that's a fact but will they get better?
