    That's gotta hurt... I feel sorry for nVidia... it does look like they're going the way of 3dfx... Maybe I should buy an ATI card next. nVidia do have good linux driver support, though - does ATI have that too?

        Im pretty sure nvidia bought intellectual property from 3dfx, not a contract that said they had to update any drivers. They bought technology, not a promise to support cards that they didn't make. People bought Geforce cards because they were technically better, not because of a big conspiracy.

        A huge pile of cash is only indicative of the past - during the heyday of the internet bubble there were dozens of companies with huge piles of cash - a year ago United Airlines had billions of dollars in the bank too - they've barely managed to emerge from bankruptcy, and there's still much work ahead.

        What matters is that a company knows what to do with the assets they have. It's awfully easy for a company to get lazy and make money in spite of themselves when everyone else is doing so too - the question is can they continue to do so when times are tough.

          For nVidia, its pile of cash is definitely only indicative of the past. However, in the internet bubble-days, a lot of companies had cash not because of earnings, but because of overhyped equity. Most of us know how to quickly spend a lot of money, nVidia has proven, in a most competitor-bloodspilling manner, that it can make it.

          In addition, take a look at all those engineers from Silicon Graphics - when Silicon Graphics made its ill move towards "normal" servers and away from its graphics niche, all those engineers abandoned ship and signed up with nVidia.

          Compare that with 3DFX, shortly before they went bankrupt they had purchased the tiny GigaPixel firm for (iirc) 1Billion USD in hopes of grabbing the Microsoft XBox contract which was at that time assigned to Gigapixel, before then, they wasted money on buying STB (don't even remember for how much there).

          I cannot comment too much on Airlines since I don't track them too much (fully commoditized, too heavily regulated, no serious money to be had in any of its niche markets).

          ... and one of them is more likely than the other to have correctly gauged the future buying needs of their customers.

          A friend of mine showed me a "handy-cam demo" of Half-Life 2, and its engine. In that demo we see the most sophisticated shaders (refraction, translucency, reflection) around, physics engine, you name it -- aside from wondering about how that much content (a _lot_ of detail in that game) could still be profitable for a gameshop, the other conclusion was that I'll probably be needing a new graphics card soon to get a decent frame rate. That kind of engine puts a heavy demand on both GPU (shaders, graphics) and CPU (physics), and I personally strongly believe that this type of engine will drive future demand for graphics cards.

          Imho, The future for graphics is only in its infancy; after the z-buffer paradigm, we still have raytracing to explore. The possibilities are truly endless.

      nVidia do have good linux driver support, though - does ATI have that too?

      hmm... i would argue, i would say NVidia has terrible support of anything other than windows, simply because the drivers are binary which causes no end of hassle if my kernel/XFree86/opengl apps are in any way different to what versions they considered or have compiled with. if you run gnu/linux or freebsd its often a pain trying to get the graphics card to work after an upgrade (ok, the kernel upgrade is not as bad as an xfree86 upgrade since they do give a few headers in the tarball, but i heard they will soon stop that). NVidia refuse to release specs of the cards so noone can even come along and write the GPL'ed/OSS'ed drivers

      ATI on the other hand release binary drivers (i heard they are good, but i dont know anyone who uses them...), specs and also have people contributing to the development of XFree86's own drivers and the corresponding kernel driverrs for linux and freebsd. if i find a bug, i can write the authors with the details; they usually fix it in CVS and the next day i have better driver. when i used to have an NVidia card i found a bug, emailed nvidia about it and got some auto-response thing which pretty much showed that i was being ignored... the next update didnt even have a fix. now, its not liek they dont claim to support gnu/linux, and its not like i hadnt paid for my hardware... so i felt shafted and bought a radeon.

    It's pretty silly paying through the nose for an expensive new graphics card when the only thing you can "play" are the tech demos.

    Sure, the card is faster so you can now play your existing games with anti-aliasing on all the time (well, mostof the time...) but unfortunately your games won't look any different.

    Remember the first time you installed your 3dfx card (inc pass-through cable) and played GLQuake? Amazing! High res smooth graphics on your P166, the envy of consoles everywhere. Then nVidia brough our their TNT cards which did 32-bit colour... nice. But since then, what's changed? Answer: not much. There are only a handful of games which use 50% of the features offered by a Geforce 3. I have a Ti4600 and a Ti200 and it's nigh on impossible to tell them apart.

      Yeah, I remember the first time I installed a 3dfx card and played GL Quake. "Holy shit" I think were my first words, followed soon after by "Holy fucking shit". I'm fairly confident that nothing will ever recreate that experience. Going from 320x200, 256 color with speed-optimized (accuracy de-optimized) software rendering at 15-20 fps to 640x480, 16-bit color with all the goodness of OpenGL (transparency, reflections, good dynamic lighting) at 30+ fps was a revelation. It's probably going to be incremental improvements from here on out, and no mere increment will ever have the sheer impact that the first 3 seconds of glQuake had.

      That said, I'm still pretty impressed with the graphical improvement since then. Compare glQuake to... Well, anything very recent that uses pixel and vertex shaders. Quake3 became a lot prettier (and faster) when I switched from a Voodoo3 to a GeForce 3. Newer games look even better (rain and water effects with pixel shaders look great). Add more trangle-processing power for more detail and the ability to have dynamic terrain (like waves in water)... I'd say we're progressing nicely.

      No, there's no reason to buy a GF4 if you have a GF3. Maybe a GF5 or whatever ATI has at the time. Skip a couple generations so that your new card really -does- have a noticeable advantage over the old, and you'll be much happier.

    I guess I too follow these stories closely, as I'm a fairly avid gamer. However, all this tugging between which graphics chipset company is better is likely to go on for some time. People say that NVidia is now the clear cut loser. Well, I wouldn't be so fast to judge that. I believe that like many other industries, there are two or more powerful companies that have good years and bad years when compaired against their competitor.

    It seems that NVidia is having a bad year or two right now. But they're a big and resoucre rich company, hopefully know what they are doing, and were just caught off guard by ATi pushing the technology in the 9700 of last year to market so soon. I think they are operating in a "catch up" mode, desperately trying to caputre back the coveted crown of the graphics wars. And it is that preoccupation that is deriding them from true technolgical innovation.

    Once NVidia resumes its roll as a technology innovator, much like ATi is now, the race once again will be on for the true champion of the graphics wars.

    And when that happens, I think that is a definate signal that graphics will again become sort of the arms race of the cold war, each side battling to be "best". But better, because when you have two free market companies battling it out, it usually comes down to as much blistering performance avalible for the dollar.

    And that is excellent for all gamers, and the general computing public at large.

      One feather that nVidia has added to their hat in the last two years is their beginnings of diversification. No longer are the completely reliant on the consumer graphics market, what with their entry into the motherboard market. They have produced graphics chips for the XBox and have made a healthy entry into the mobile graphics chip realm. A couple (few?) years back they received a contract from the US Gov to produce graphics chips for displays in military jets (if memory serves).

      They have much more going for them then being purely a gaming chip company. Given time I suspect that we'll see nVidia and ATi oscilate the leadership position. nVidia, while in the valey, has other businesses to fall back on.

      While not always the case, companies with a backup plan tend to be more willing to take risks simply because if the risk doesn't pan out it doesn't spell disaster for the company. I think that we'll see more inovation coming from nVidia yet.

    Again, this proves the superiority of Direct3D over OpenGL and the 'schism' between ATI and NVIDIA. Programming for OpenGL is not compatible, unless you handle all render path for all targets (take time). Such things wouldn't happens if the Dawn demo was Direct3D.This also proves that ATI could write drivers which can handle all the Nvidia OpenGL proprietary extensions (not what they doing actually). They are supporting a couple of extensions , but for example GL_NV_occlusion_query for example, is supported on my Radeon 8500. But I like to see GL_NV_point_sprites for examples (actually you can't do point sprites on ATI (ie particles) under OpenGL, except in Direct3D).Theses students should contact ATI and give the source code of their modifications for the next ATI driver.That, would be really nice and legal. These extensions are approved by OSI anyway. Sadely, for 'policy' reasons, it won't be accepted by ATI (I've already tried that in fact).

    The John had a .plan update before which pointed out that NVidia's card is actually cranking out more precision by default compared to ATI. That could explain why ATI runs faster by default. When he used an NVidia-specific rendering path (where the precision is more or less the same as ATI's), the NVidia card actually ran faster.

    Is this somehow related to the discrepancies in this fairy demo?

    I haven't tested this (I don't own an FX nor an ati card with the balls to run it) but on the VE3D forums someone mentioned this to make Dawn naked:


    Well for you sickies looking for the nude patch, no need. Just change the fairy.exe file name to one of two things. Quake3.exe will make her nude, and 3dmark03.exe will make her nude and wingless.

    On some other forum (here) [nvnews.net] they talk about renaming some file to get rid of her erm.. cloths/leaves. :) Enjoy.

    From what I understand, the FX5800 is a crap card. A review at tom's hardware [tomshardware.com], however, shows the FX5900 pretty much beats the crap out of anything ATI has right now. I'm sure this will change with the next iteration of hardware, but hey - it always does.

    Either way, we should stop talking smack about nVidia when the best card on the market pretty much depends on when you're looking for it ;-)

    3D graphics are still very much a niche on the PC. This may change with Microsoft's plans to do something like Apple's "Quartz Extreme" in a future version of Windows, but at the moment there are still only a relative handful of games that even require a hardware transformation pipeline (available since 2000), and there are even fewer that do anything at all with programmable shaders (available since 2002). At the same time, the slide in the PC game market continues. A lot of people, including myself, expected it to turn around a bit by now, but no dice. What the PC does have is a couple of games that will be hig with hardcore gamers: Doom 3 and Half Life 2. In a lot of ways, nVidia and ATI are designing cards specifically for those games, and not the perceived 3D market in general.

    In short, the race for the high-end video card market is increasingly meaningless, especially with the growing shift away from desktop PCs and the ridiculous power consumption and level of cooling required for high-end cards. If GeForce 2 class chipsets start shipping in an all-in-one, cool running, silent PC, then the real goal has been achieved. Gamers and CG people who want or need to blow $400 on a new video card + 10lb heat sink combo every few months can still do so. That's not a mass market industry any more, though.

    ATI compatibility, big frigging woop!

    If anybody wants to do something actually useful they can get rid of those frigging fig leaves!

  • Image quality not improved (Score:5, Interesting)

    The article claims the image quality was improved, but the first thing I noticed when I opened up the one of the 4xAA screen shots was that the antialiasing on Dawn's hair isn't working properly in the ATI version. The NVIDIA demo uses the GL_SAMPLE_ALPHA_TO_COVERAGE_ARB feature to feather out the hair at the ends. (This makes the card use the alpha value of a fragment to determine the number of covered samples when multisample antialiasing is on.)

    Check out the hair on this NVIDIA shot [nvidia.com]

    and compare with the hair in this shot off the ATI [rage3d.com].

    The zoom on the NV example isn't quite as close-up, but you can still see how the hair feathers away at the tips, while the hair on the ATI is all jaggy and uniform thickness right out to the tips. Like some kind of Raggedy Anne yarn hair.

    So does the ATI not support alpha-to-coverage? Or did these guys making the wrapper just not translate it properly? The hair looks pretty bad without it.

    I seem to remember when I saw the NV guys give the demo that they made a point of how expensive the hair was to render. Each hair is a separate GL_LINE_STRIP, there are thousands of them, and if you turn off the complicated blending and smoothing on each one of those little hairs, that could maybe add up to a large savings. I don't know, but I wonder if that would account for most of the speed-up they see running it on ATI.

    Still a neat hack. It would really rock to have complete NV<->ATI compatibility dlls that would work for all apps and not just this demo.

    While they may have made some slight improvement to one aspect of image quality by improving normalization, which I guess makes the lighting a little more accurate, I really doubt the improvement is all that noticeable. Maybe I could tell given a side-by-side comparison, but I doubt I would notice if only shown a version normalized one way or the other. On the other hand, that ugly hair is pretty obvious. To me that makes the NVIDIA sreen shots look better.

    I was excited to try this out last night, and it runs beautifully, but after readon the comment about the hair (how its not shaded to kind of fade out), i also noticed that Sawn has no eyelashes, and aparently does on the nvidia cards. Having seen the demo on boh cards, i cant say technically why the ati does in fact seem to have a nicer overall image (is it the gamma, is it actually what rage 3d mentions?), but nonetheless, this is still a really, really cool hack. Now if we get the hairs back, can have an even match up~
