    Wow a sensible post that actually got moderated up. At last!

    I'm sick of the blatant bias in the /. moderation on this issue, and this is one of the few exceptions. The moderators don't appear to have clue 1 about OpenGL graphics issues and have let Precision Insight confuse the DRI & OS issues and now are moderating up an unjustified onslaught against nVidia, and why? They have the temerity to develop great drivers for Linux. NVidia are not leaning on the community and throwing half baked rubbish over the wall but have put in the time and dollars to write a real quality OpenGL implementation.

    These drivers are FAST, I mean REALLY fast! They are also extremely functional. This is probably the fastest most functional OpenGL implementation available for Linux, so set the OS issue aside and thank nVidia for seeing Linux as important enough to put in the development effort.

    Ask them nicely for source code, begin that next step now that we have great hardware accelerated OpenGL on Linux. Don't flame off at them like rabid animals, appreciate what's been done but ask for more.

  2. Re:Hold on - High resolutions on 3dfx Voodoo5 vs NVIDIA GeForce Preview · · Score: 1

    Anandtech & your conclusion is wrong.

    There is a very sound technical reason for the difference at various resolutions. The GeForce has hardware T&L which outperforms the CPU T&L of the voodoo. The voodoo on the other hand has more raw textured fill performance. This means that the voodoo can beat the GeForce on an application which is fill limited, but a GeForce can beat the voodoo on an application which is geometry (T&L) limited. In very simple terms the higher resolution applications tend to be fill limited and reducing the resolution places a greater emphasis on T&L performance. So, the results you see are not likely to change greatly with newer drivers because 3Dfx have highly optimized software SSE & 3DNow! T&L code after years of development.

  3. Exactly as you would expect. on 3dfx Voodoo5 vs NVIDIA GeForce Preview · · Score: 2

    There is no surprise here.

    The GeForce wins on geometry (T&L-transform & lighting), the Voodoo wins on textured fill. Bear in mind that this was an SLI version of the card with two VSA-100 parts.

    If you want high resolution go for the 2 part 3Dfx card if you want all round performance go for the GeForce. A single part Voodoo card is going to be a poor performer.

    One thing the article didn't touch on is the CPU speed dependency for the voodoo, this system had an 800 MHz processor, if you have a slower processor or one without SSE instructions you can expect the voodoo to be worse at some of the intermediate resolutions because it will be more T&L bound. The GeForce has much less dependency on the CPU because it offloads the T&L to the CPU, in addition the CPU is able to do other stuff while the card is busy in a well written application. The other point to note is that with a FASTER PIII the voodoo will begin to catch up to the GeForce, even at the lower resolutions, so a 1GHz PIII would work more to the voodoo's advantage at least in the benchmarks.

    So, if you're upgrading your PIII 500 or any early Celeron system (the latest Celerons have SSE older ones don't) you should really go for the GeForce, if you are building the latest 1GHz power system then the voodoo looks like a good bet especially if you are running at high resolution. If you're CPU somewhere in between then decide what's more important to you, geometry or fill.

  5. Unisys are actually doing us all a favor! on Unisys Cracks The Whip · · Score: 1

    It's just the gif compression which is at issue. You can still use gif files but you can't use compressed files unless you get a license. This is tragic since it's a relatively obvious optimal binary level dictionary based compression, and any number of alternatives compression schemes would have done quite nicely instead. Even if gifs had given you some kind of choice of compression we'd all be in better shape.

    What's really odious is the way Unisys is trying to enforce it's patent rights here. Not only do they want fees from major application providers but they are now chasing end users too, basically anyone who wants to use the gif format with compression. This is a rather dubious approach since web designers often use packages which have ALREADY licensed the LZW algorithm. Unisys have a pretty screwed up notion of what their I.P. is worth and are darned fortunate that gif files happened to use their compression algorithm, they basically struck gold by pure accident. The rest of us are fortunate that gif compression is optional but it still isn't ideal.

    In some respects you have to admire their guts. They're in it for the money, plain and simple. They know that and also know how long the gravy train will run before it derails and they're making the most of it.... simply because they can. There are no relationships to be managed and no follow-on business, they just gotta milk this cow until it dies. That is the nature of corporations in a situation like this, they're in it for the money, it's no use wagging your finger at them, they almost have a duty to maximize the benefit from this little accident.

    What is surprising is the momentum behind the LZW in gif files, PNG took a while but a simple modification of the gif format to allow another compression algorithm would have been a viable alternative for gifs.

    PNG is long overdue and very welcome for many reasons, it's just MUCH better on so many levels, gif won't be missed. If this patent nonsense helps displace gifs with PNG files then Unisys will actually be doing everyone a favor, and that is wonderfully ironic.

The nVidia drivers due out will be high quality and will export the same functions everyone else does, it is proprietary code which they aren't obliged to give away it isn't based on Mesa, it's based on the SGI SI. So it will 'just work', and it will work with XFree86 release 4.0. So what's the problem here?

    Linux should be able to tollerate companies supporting their platform without this kind of political nonsense. Look at what's going on here, nVidia make great cards and decide to support Linux with real completed drivers which pass the conformance tests. Precision Insight are attacking them because they intend to deliver a driver which uses an infrastructure which isn't based on Mesa and isn't Open Source. That's nuts.

    The key point here is that the OpenGL implementation will export quality OpenGL functions and with the finalized ABI and the XFree86 4.0 infrastructure it doesn't matter a hoot what the underlying implementation is based on. In fact it may pass more of the conformance tests than Mesa currently does.

    D3D is a part of DirectX and most DirectX games use D3D now, obviously 2D games like Starcraft would be an exception as would a game which uses OpenGL for 3D and DirectX for sound & peripheral input for example Quake2. This means that, in many cases, the claim that DirectX works flawlessly in not compatible with D3D not working well.

    The only way you are likely to get D3D working reasonably well with the required hardware acceleration on a broad range of graphics cards is to leverage the OpenGL driver work being done now. What is required is a D3D emulation layer on OpenGL, (some preliminary work exists out there for OpenGL on D3D and vice versa). Some areas would be forever problematic but at some point in the future when XFree86 version 4 is out with many drivers available based on Mesa or the SGI SI or homegrown code, you'd have a reasonable chance of getting functional workalike D3D via emulation code on OpenGL.

    You could still implement a native D3D implementation for some cards instead of using the emulation layer for OpenGL, but the emulation layer would be the right approach to getting broad and reasonable hardware acceleration quickly by leveraging existing driver work.

You have some choices there, with commercially available X servers which support GLX or Mesa based hardware acceleration in Xfree86, things are progressing rapidly on the GLX/OpenGL acceleration front, just make sure you have a plan in place to get acceleration which is compatible with your hardware, unfortunately this doesn't work out of the box yet, so you'll have to play with X servers, drivers and Mesa, depending on your card & approach.
    You can always switch the card so it may make sense to get your initial development systems and remain flexible about the graphics cards. See what works best for your applications during the port then finalize on that card and driver setup. By the time you deploy you can be sure the driver situation will have improved immensely so a graphics card final selection before fielding the solution would probably be appropriate, and you only have to swap out the card in your development systems which will be a relatively small portion of the system cost on a small number of systems.
