Batman: Arkham City
After a rocky launch last month, Rocksteady finally got their DirectX 11 problems sorted out for Batman: Arkham City earlier this month. Batman: Arkham City is loosely based on Unreal Engine 3, while the DirectX 11 functionality was apparently developed in-house. With the addition of these features Batman is far more a GPU demanding game than its predecessor was, particularly with tessellation cranked up to high.
At Extreme settings Batman is quite daunting for our entire GPU lineup at 2560. Nothing except the GTX 590 can crack 60fps, though the 7970 begins to come close at 52fps. Relative to NVIDIA’s lineup Batman ends up being one of the weaker games for the 7970, with the 7970 only taking an 18% lead over the GTX 580 at 2560. As for the 6970, the 7970 has another very strong showing opposite AMD’s previous generation, beating the 6970 by 44%.
At 1920 we’re still using Extreme settings and the story is much the same, though the 7970’s lead drops a bit more. Against the GTX 580 it’s now only 14% faster, and against the 6970 it’s 35% faster. Things do eventually pick up at 1680 when we back off to Very High settings and stop using MSAA, at which point the 7970 takes a surprising 32% lead over the GTX 580 while the lead over the 6970 jumps back up to 47%.
Looking at all of our cards it’s really the 5870 that tells the whole story. Tessellation plays a large factor in Batman’s performance, and as a result the partially tessellation-constrained 5870 absolutely struggles even at 1920. Consequently this is further proof that AMD was able to get a great deal of additional performance out of their geometry engines even with the 2 tringle/clock limit.

Yep. Still working on it. Hold tightMadMan007 - Thursday, December 22, 2011 - link
Np, just not used to seeing incomplete articles publsihed on Anandtech that aren't clearly 'previews'...wasn't sure if you were aware of all the missing stuff.DoktorSleepless - Thursday, December 22, 2011 - link
Crysis won't be defeated until we're able to play at a full 60fps with 4x super sampling. It looks ugly without the foliage AA.Ryan Smith - Thursday, December 22, 2011 - link
I actually completely agree. That's even farther off than 1920 just with MSAA, but I'm looking forward to that day.chizow - Thursday, December 22, 2011 - link
Honestly Crysis may be defeated once Nvidia releases its driver-level FXAA injector option. Yes, FXAA can blur textures but it also does an amazing job at reducing jaggies on both geometry and transparencies at virtually no impact on performance.There's leaked driver versions (R295.xx) out that allow this option now, hopefully we get them officially soon as this will be a huge boon for games like Crysis or games that don't support traditional AA modes at all (GTA4).
Check out the results below:

If nVidia released this card tomorrow they woulda priced it easily $600... The card succeeds in almost every aspect.... except maybe noise...chizow - Thursday, December 22, 2011 - link
Funny since both of Nvidia's previous flagship single-GPU cards, the GTX 480 and GTX 580, launched for $499 and were both the fastest single-GPU cards available at the time.I think Nvidia learned their lesson with the GTX 280, and similarly, I think AMD has learned their lesson as well with underpricing their HD 4870 and HD 5870. They've (finally) learned that in the brief period they hold the performance lead, they need to make the most of it, which is why we are seeing a $549 flagship card from them this time around.

waiting for amd's 28nm 7770.this card is overkill in power and money.

Same, we're not going to tax these cards at the most common resolutions until new consoles are out, such is the blessing and curse of console ports.
