NVIDIA's GeForce 7800 GTX Hits The Ground Running

Wolfenstein: Enemy Territory Performance
As an older OpenGL game that lacks any fragment programs (OpenGL's equivalent of DirectX Pixel and Vertex Shaders), most of these setups breeze through it, even at high resolutions like 2048x1536. The only setup that doesn't provide smooth frame rates with AA/AF enabled is the 6600GT. There is clearly a problem with the SLI support in Wolfenstein 3D, as both the 6800U and 7800GTX both run slower in SLI mode than in single card mode. We would assume that the 6600GT SLI is also failing to take advantage of the second card, so the relatively low frame rates in AA/AF mode are due to driver problems more than anything. Also of note is that despite the lack of advanced pixel effects, Wolf3D is relatively CPU limited. 120 FPS even with an FX-55 appears to be the maximum.The one noticeable advantage of the 7800GTX is that it makes 2048x1536 4xAA a truly playable resolution, even for competitive online gamers. The speedup at 1600x1200 4xAA is only 18%, but 2048x1536 runs almost 50% faster. If you have a monitor capable of running such a resolution, the 7800GTX is one of the few cards that can actually handle it. When (or perhaps if) NVIDIA fixes the SLI support for Wolf3D, we should also see acceptable frame rates out of the SLI setups even at the maximum resolution, though given the popularity of the game we have to wonder why NVIDIA hasn't already included proper SLI support.
The ATI side of the equation is once again lacking. While it is more or less able to match the 6800U, ATI clearly has no current answer to the 7800GTX. We'll have to see if Crossfire does better with accelerating Wolf3D than SLI. If it does, we expect NVIDIA to suddenly find the impetus to actually get SLI support working properly.

THE SLI is meant to played on high res.. if you got money to brn on SLI then i am damn sure you got money to burn on a 19" monitor ;)CtK - Wednesday, June 22, 2005 - link
can Dual Display be used in SLi mode??Johnmcl7 - Wednesday, June 22, 2005 - link
In general 6600GT SLI performance seems a bit random, in some cases it's really good as with BF2 but in others not as good as a 6800GT.John

Anyone notice how a SLI'd 6600GT is just as quick as a 6800 Ultra in BF2?R3MF - Wednesday, June 22, 2005 - link
give me some details on the 7800 and 7800GTwhat, when, and how much?

#59I am more eager to see how the new midrange cards will perform than these parts but if I had a spare $600 I would jump all over this.

#56LMAO!!!!

#44And I thought paying $350 for a video cards was too much then or even before than there was the $200 high end and before that the $100 high end. I balked at all of those prices but I understood why they were prices as such and didn't bitch everytime the costs went up. The bar keeps being raised and the prices go with it. Inflation, more features and the fact that most of us here can afford $350 video cards pushes the cost of new PREMIUM cards higher by the year. It's only going to go up unless either people quit buying the high end cards or the manufatucrers find a magical process to reduce costs dramatically.

You're quite right, there's always a premium for the best, I don't see any difference here, no-one is being forced to buy this graphics card. As usual, I'll wait until something offers me a better price/performance ratio over my current X850XT/6800 Ultra duo.John

Seems to be a problem with the last Knights of the Old Republic 2 graph. Both 7800GTX setups are "performing" less than all the other cards benched. Despite all the mistakes, it still seems like I was right in that this card is made for those who play at high resolutions. Anyone with an R420 of NV40 based card that plays at 16x12 or less should probably not bother upgrading, unless they feel the need to.
