Quote:

ATI's competitor NVIDIA has sat down and put together a presentation dealing with the shortcomings of CrossFire. Problems like limited resolution and game issues are listed. Not only do they cover the CrossFire video cards, but also problems with ATI's dual VGA motherboard chipsets.

Yea, it was his scoop, so i felt it'd be only fair that he post it...but if its one thing i could never discourage, its cooper's consistency in posting news :up:

Good Job :)

Bah I bet thats all fixed thru drivers. Remember SLI has been out for quite a while, AMR is new.

AMR was one of the possible names ATI was thinking for Crossfire, but we now know for sure that its crossfire.

I can see how you could get a tad confused though as Nvidia mentions AFR not AMR, which is Alternate Frame Rendering (AFR) which is the primary rendering mode used by SLI and one of three used by crossfire along with supertiliing and scissor.

i dont think max refresh can be fixed thru drivers.. isn't it a hardware limitation?

I still wouldn't be so sure that Crossfire is limited to 1600x1200 60hz. That seems like a large problem that could be avoided

But isnt there like NDA and stuf?

This compilation of press articles and assumptions doesn't look all that real to me. Is it an internal Nvidia presentation? An official Nvidia marketing presentation? Or just some fake?

If that's the way Nvidia is marketing their products, they just lost a customer.

I think there's some news thread about this. But, it doesn't seem to be limited to that res, it's just that 52 Hz might not be too forgiving to your eyes.

is HW limitation to be exact DVI limitation.... but scissor mode (from what ive read can handle it not 100% sure just asumptions) but is true that the limit is the DVI bandwith that is way too low

The internal comms (ie card to card) is handled by a decoder that can mange 1600*1200 @ 60hz. The external decoder (ie card -> VGA) can handle 2058*x @ 85hz iirc. Res and refresh arent going to be a problem....

If this is t rue, then it doesn't seem to be such a flickering issue afterall. Smoothness is acceptable at 60 FPS. Even 52 FPS is quite sufficient on a widescreen LCD. 2058*x might be a problem though.

Well, it's about TIME that we got objective information about Crossfire!

I've been sick and tired of these "third-party" comparisons of Crossfire and SLI. After all, who knows Crossfire best than ATi's sworn enemy?

I hope you just forgot to put a smiley in your post.

I was not referring to the refresh rate, I said FPS. Why I even mentioned LCD was because I don't know of any CRTs supporting 1920x1200 resolution in 16:10 native aspect ratio.

That must be ATI, surely. Especially since they're not in it for the money either.

EDIT: out of chill pills?

I would, if I had the cards ;)

I hope this isn't true. It will be good for nVidia, I like some competition, but it must be fair ;)

most is annoying marketing propaganda but there are some interesting infos in there.
i hope ati listens to this criticism and tries to improve their products. imo its just sad that this is comming from nvidia and not from some objective author, most people are too scared to lose support if they criticize a mfg :(

and it ends up in nvidia and ati throwing mud at each other :/
i bet we will be hearing a reply from ati marketing to this as soon as r520 gets released :rolleyes:

What a load of crap. There hardly going to say it's brilliant and yo shoul buy it instead of SLI. nvidia just :banana::banana::banana::banana: off, and do your own thing. grrr this pisses me off.

Hicks, ATi and NVidia do this back and forth all day long. Infact, the last one was done by ATi, BS Bingo anyone?

No smiley. I figured most people here would be smart enough to figure it out.
