on the Xbox 360 the engine runs at 
30FPS not 60.

also it dnst have AA on the xbox 360

so my cheap 8600GT > xbotch

Lets see how your 8600 GT runs GoW when it comes out.

"PS3 is an NV7X part, it isn't capable of Full HDR + AA in DirectX (see: Oblivion). This is a hardware issue." 

PS3 does not run games using DirectX (obviously, as thats a MS thing). But regardless it does not matter, because like you say it cannot do HDR + AA. 

And you can run UT3 with AA on Nvidia 8xxx cards, i can get it running myself on my 8800GTX. And even Legion Hardware in there look at UT3 performance have done it. That article is even linked in one of the articles on here. http://legionhardware.com/document.php?id=693

MSAA will be available in DX10, according to trusty 'ole wiki...

have you looked at the edges of objects? ut3 has post-processing

So ps3 wont have anti-aliasing at all?

PS3 is an NV7X part, it isn't capable of Full HDR + AA in DirectX (see: Oblivion). This is a hardware issue.

The post processing in UT3 is supposed to mellow out all that alaising. Even on the 360, the deferred renderer of UT3 relies on motion blur, depth of field, and darker colours to hide all those jaggies; there was no AA on the X360.

<i>PS3 is an NV7X part, it isn't capable of Full HDR + AA in DirectX (see: Oblivion). This is a hardware issue.</i>

The PS3 does not support Direct X. The rest of your comments are ignored.

It has AA. Why do I believe that? Because I have played this UT3 demo for two days now with AA enabled.

This works atleas with Nvidia cards:
1. Use the most recent drivers you can find
2. Rename UT3demo.exe to Bioshock.exe
3. Go to NVIDIA control panel and just change Bioshock settings

I have C2D E6300@3.04GHz+2x1024MB+ 8800 GTS 640MB@ 650/2000 and following settings were best playable:
1650x1080+ 8xAA 16xAF + everything as high as possible. According to fraps min. fps was 31, average was 45. 

High Quality AA was too much for my 8800 GTS.
