Radeon xfx 5770 HD. Dx 11 support?

[Jangalomph]

Well short and simple. I just got a radeon xfx 5770 HD Dx 11, 1 gb GDDR5 memory graphics card. Supposed to be the best card on the market. And i'm amazed with it. crysis on high with no overclocking and no choppy frames. I havn't tried very high, but i'm sure it could run it on very high with no problem. L4d2 excellent. 70 - 80 fps on the highest possible settings even MSAA, I could never run MSAA, Any ways. The question is... i have windows XP if i get a dx 11, or dx 10 game like crysis "dx 10?" Can windows XP run dx 10, or do you have to get like windows 7 or something to run dx 10 - 11?

Only Vista and 7 can run dx10 or 11, I'm afraid. An upgrade is in order.

[FlynT]

Nothing more to say but pls ignore vista and skip directly to Win7.

Dx11 takes normal mapping and actually creates new polygons tessellation). Looks amazing on rocks/bricks.
Water also gets a huge upgrade, and waves/ripples behave dynamically, and look pretty legitimate.
Various other awesomeness

Hah, looks like I'm going to have to go work a bit so I can afford a new hardware upgrade.

I don't think that's entirely true, it does have hardware support for tessellation, but it's not automatically applied to something with a normal map.

And I may be wrong about this too, but I think that all the tessellation samples I've seen have been running off heightmaps, not normal maps, considering normal maps don't offer any kind of height information, just surface orientation per texel.

Well, i want window's 7..

Any one willing to buy me a legal copy? Any takers?

[Xburn]

Little off-topic, but Vista is now much better and faster after the service pack 2 update.... But still it would be better to get Windows 7. At least I think so.

[Meathead]

Yea windows 7 will make a bigger difference for you I got the 5750's and it does!

If you're a student you can buy it legally for $30.

On the tessellation thing: it's essentially parallax occlusion mapping but all fancy sounding and it's a huge performance hit. It's cool, mind you, but I'm curious how it may or may not be better.

Oh, finally jangalomph- you can actually use SSAA (which looks WAAAAAAAY better than MSAA) with DX9 games, so that's something to look at.

No, it's not. Parallax occlusion mapping uses clever shading to create an illusion of depth. Tesselation uses a map to add polygons (not for shading). For example, tesselation improves detail near the edges of stuff. Parallax occlusion mapping looks like sh!t near edges. Also, it would be a huge performance hit if it was done in software, but we have new GPUs that do most of the work in hardware resulting in a small performance hit.

Wow that demo was awesome. It made it my Christmas even harder as I'm stuck between getting a 15-18 IS USM lens for my 50D or a new rig. Phenom II X4 3.2Ghz, ASUS M4A79T Deluxe AM3, HD 5870, Blue Ray drive, Monitor.

Yes, I know it's not the same thing, but it accomplishes much of the same results.
POM


Tesselation


Also, it is not a minor performance hit. It is a HUGE one which nearly halves performance. Yeah, it's a little prettier than POM, but it does essentially the same thing at a massive performance detriment. I would have to ask, with performance like that if having mildly nicer edges is worth destroying your framerate.

As technology improves though that performance hit will lower and it'll be worth it to always have it look that tiny bit better.

Also I don't know why you guys are fighting over this.

[cheesemoo0]

There is a hack to get Dx10 on XP, but I wouldn't bother.
