Everquest 2 Performance
Unfortunately, this is one of the games that we couldn't get AA working at all. Our test with AA shows performance to be very high, but the benefit here is small indeed. It seems that the upper limit of performance under the "Very High Quality" setting around mid-day Everquest time is near 45 frames per second at 1600x1200. We did test Extreme Quality and reached a good 9 to 12 fps on CrossFire.With AA on in combination with Very High Quality, Everquest 2 looks great, and when ATI fixes whatever issues that are going on here, it's clear that CrossFire will bring excellent performance to EQ2 addicts.

It depends on the person. I can notice a considerable amount of ghosting in a fast paced game like UT2004 even on an 8ms LCD.I would never go with an LCD for any kind of gaming for a number of reasons, but anyway I got a top notch CRT a month ago and don't need to worry about LCD limitations for a couple of years at least.

I'm a laptop gamer. I've got an older Mobility Radeon 9700 Pro, so I can't run everything at the native screen size of 1400x1050. As such there are many games that I play at 1024x768, or even 800x600 in the more extreme cases.Games look just fine with modern LCD scaling. That is to say, a 1024x768 game looks very good scaled up to 1400x1050. When ATI was designing their scaling algo, they obviously focused on making the pixels look square, rather than just doing a simple bilinear transform.
The point of scaling on LCDs may be moot to serious gamers though, as modern desktop cards often don't need to run games at below native res. And when they do, I can report they still look good scaled up.
I can also report that the response rate ("motion blur") is totally overblown. I've got a laptop, which obviously means I've got a pretty high response time (Probably 25ms to 30ms). Motion blur is noticeable, but isn't really distracting except in very bright areas. Desktop LCDs have improved a great deal beyond this with significantly lower response times to the point where it isn't an issue at all. I understand contrast ratios have also improved. All that is really left is colour saturation/accuracy (as a thing that CRTs are better at).
Most gamers I know with modern PCs have LCDs now. CRTs are dying, slowly but surely, much like DVDs slowly replaced VHS. LCDs already outsell CRTs, and adoption among gamers is possibly even higher than the regular computer buying public.

#23 no serious gamer would play in a window, and how can you not see the drawback of shrinking the screen size to get a lower resolution? Why turn a 19" display into a 14" display? I'm sorry but my 21" crt can do any resolution and still use all of the screen space and not interpolate. LCDs can't period and that's a big deal for 99% of gamers. Oh and #21, CRTs will be around until there is a technology that is fit to take its place. LCD panels are not even close to the quality of a good CRT display.blwest - Friday, July 22, 2005 - link
Can we do this benchmark on a NON ATI chipset?Samadhi - Friday, July 22, 2005 - link
This article shows the need for a lot more reviews of high resolution LCD devices from a gaming perspective.fungmak - Friday, July 22, 2005 - link
Anand or Derek - two quick questionsWhats the configuration of the slave and master card. Is it an XT as master and XT PE as the slave?
Obviously the speedup for crossfire would be a little bit more if you just used regular XTs instead of XT PEs for the single, if it was just two crossfired XTs.
Finally, in the Far Cry benchmarks, the single ATi card is labelled as the XT, but in the others, the single ATi card is an XT PE. Is this a typo?

Seems like they were CPU limiting most of the benches, only 1600x1200 isnt demanding that much from the 6800 Ultras, x850s, and 7800s in SLI.BuddyHolly - Friday, July 22, 2005 - link
This is not quite a paper launch, but more like a paper review. Almost useless in helping me decide what my next video purchase will be other than to show that Crossfire does in fact work.How about the important stuff? When will it ship? How much? And where is the next generation ATI card and when will it ship?
I want more competition so I can retire my 9800pro and get a PCIe card, motherboard and processor without having to morgage my house or go without eating for a month...

To Derek WilsonWhich ATi driver did you use for the CrossFire setup?

So the point of this is that Crossfire with two last-gen GPUs (XT850s) doesn't perform quite as highly as SLI with two current-gen GPUs (7800s)? That makes sense. If/when the next-gen (current-gen) ATI cards are released I would expect them to do as well or better when Crossfire'd compared to SLI'd 7800GTXs. We shall see. :)
