Battle in the Canal

Our first benchmark is packed full of just about all of the stressful elements you will encounter throughout Half Life 2.  The demo starts aboard a boat driving in a tunnel before making a splash into a wide open body of water.  The boat is piloted over to the shore where the player dismounts and heads inside for some action.  

While inside the flashlight is used to illuminate dark areas and the player encounters a few firefights before heading upstairs to the outside.  While outside (and while being pursued by a helicopter) the player encounters a few enemies on his way into a warehouse.  The demo concludes inside the warehouse. 

We created this demo because it incorporates just about everything – water, the flashlight, a vehicle, engaging enemies indoors as well as outdoors and sunlight.  Since we’re dealing with all very capable cards here, let’s first look at performance at 1280 x 1024.  Remember that we used the highest detail settings with the exception of anisotropic filtering and antialiasing, which were both disabled for this test (we will look at their impact on image quality/performance later on in this review).

We’ve already looked at the performance of the Radeon 9700 Pro and the Radeon 9800 Pro, those cards are only included so you have a way of tying the performance of these GPUs to the ones we compared in Part 1 (the numbers are comparable). 

The non-Pro Radeon 9700 does very well, as does the Radeon 9600XT.  If you look at the performance difference between the 9550 and the 9600XT you should have a good idea about how intermediate cards like the Radeon 9600 Pro should perform. 

The GeForce FX 5900XT performs absolutely horribly here as you can expect.

The resolution scaling graph is particularly important here because not all of these cards are best suited for 1024 x 768.  ATI’s Radeon X300 is particularly interested because it actually performs relatively well at 800 x 600 (as does its competitor – the GeForce 6200).  Remember, we’re looking at DirectX 9 performance here and even the $80 X300 SE is playable at 800 x 600.  Not bad at all. 

Next up we look at DirectX 8 performance, for these graphs we’ve taken out the 9700 Pro and 9800 Pro as you’d have no reason to run either of those cards in DX8 mode. 

The Radeon 9700 and the 9600XT continue to do extremely well here but this time around, the GeForce FX 5900XT actually offers very solid performance.  When Valve said that you should treat the FX series as DirectX 8 hardware, they weren’t kidding. 

Owners of older GeForce4 cards should be pretty happy with DX8 performance as the Ti 4600 was quite playable in our at_canals_08 test.

    I have geforce4 mx 440, with 1.7ghz intel cpu and the frame rate is unacceptable, jittery all to hell, stupid HL2 autodetects it as dx7.0 card, I forcefully correct but still. How the hell are you pulling off frame rates like that with that particular card? I barely get a stable rate at 800x600 res at 20fps. I see lots of red and usually yellow when I use cl_showfps 1 in console
    There's something completely messed with this game it shouldn't run like this.

    Counter strike source is unplayable, I can't get over 10fps in it. Usually it hangs at around 3 to 6 fps.

    I'm pissed off I spent $60 on a freaking game that does SH*T for me. I already beat it but it's so not smooth and jittery I'm surprised I could even hit the side of a barn.

    "The next step is to find out how powerful of a CPU you will need, and that will be the subject of our third installment in our Half Life 2 performance guides. Stay tuned..."

    Yeah, im waiting like hell, i wanna se how HL2 performs on old CPUs, i have a TB1200 and a GF4 Ti4800SE, Graphics perfomance was OK, but the game playing was really sluggish, but still very playable.
    And i wanna se som comparison graphs on how different CPUs perform, and i've been waiting, when do we get to see the HL2 CPU roundup? :)

    take a look on this link, here are some interesting info about how to improve performance on geforce fx users in about a 50% on dx9 mode. Try it yourself. The link to the article is:
    I hope this can help to some geforce fx users... :)

    Did anyone else notice the piers and pylons don't have reflections in the screen shots on page 2, Image Quality, the second picture, the one of the water and damn/lock.

    When you roll over, you see the non-reflexion version in dx8, rollback and something looks funny. The refelctions look good, but there are lots of things missing, most obviously the piers, aslo some bullocks? (things you tie ropes to)
    Hmm, maybe the pier is a witch, or is it a vampire, so it has no reflection....

    Other than that, the game is awesome. I'm well into city 17, and only took a break because the wife was becoming more dangerous than the Combine.

    Running on a Athlon 1.7 512Mb and Saphyre Radeon 9000 128Mb?, it it plays fine excepte the hickups at saves and naptimes at loads.

    This whole ATI/Nvidia DirectX/OpenGL optimization is driving me insane. Developers need to stop trying to optimize and code for "universal" video cards.

    One reason why DirectX/OpenGL was created, was to make it easier on developers when accessing different video cards. It is a "middle man", and the developer shouldn't have to know what card someone has in their system.

    But now, all these developers are using stupid tricks to check if you have an ATI or Nvidia card, and optimize the paths. This is just plain stupid and takes more time for the developer.

    Why don't they just code for a "universal" video card, since that's what DirectX/OpenGL was made for?

    'Glide' all the way!!!
    I used to run Diablo on a voodoo2 and you could switch from glide to Dx and glide looked so much better! even after upgrading to a geforce card glide looked better... not that its relevant here. heh

    #55 OK I agree. No I was not trying to saying that 6xxx is bad, or that it will be bad. Nor I think it superior do Ati X line and vice versa. But we already have the "bad" example of the nvidia FX line (for games), how will both scale?! I didn’t like 3Dmark bench, but was 3Dmark03 that bad? It was already showing something at the time….

    One day I said here it was important to bench an Ati 8500/9000 vs Geforce3/4 using current drivers (and platforms maybe too) with new and older games to test.
    This is very important since you will know if support to older hardware is up to date, and also how is performance on these cards today.
    I am not saying that while 8500 loosed to Geforce4 in the past, that it will win today, I just want to know how things are now! Is PS1.4 of the 8500 giving it any thing now since then it doesn’t? I don’t know!

    But everyone said the test was pointless and that there where no need to bench "older" hardware, since no one was planning to buy it....

    well it kinda matter what you do with your computer. Personaly i like my 5900XT over the 9800Pro i have because it is faster in 3D Modeling software.. But for gaming the 9800Pro is fare better.

    But as you say that the NV3x wasn't bad then but now, well i think it was bad then just had nothing to prove it. Now that their is a lot of DX9 games out the poor mistake on nvidia engineers show. And they know they missed up thats what the 6800 can use a 16x1 pipeline config. I belive the 59xx's were 4x2 and the 9800 was 8x1. the 6600GT also shows nvidia's mistake being that it is a 8x1 and beating the paints off the 4x2 5900 series.

    But i was unsure about if you were tring to say in your last post if you think nvidia fudged again and that it will show in due time with the 6800 series, but if this is the case and you are tring to say that. I don't think so and i believe Nvidia truelly has a very compeditive card that meets the demands of all users.

    #52 You are right. I was talking about the NV3x core. But dont forget that this CHIP was not that bad at the time, its really bad TODAY!

    Example: Now who is better served, who had bought a 5600/5700 or a 9600 card?

    #48 may be that dx8 water looks that crappy while dx8.1 water looks like what you and I are seeing Reply
