The Unreal Tournament 3 PhysX Mod Pack: Finally, a Major Title

Unreal Tournament 3. Metacritic gives it an 83 for “Generally favorable reviews” and NVIDIA released a PhysX mod pack for it last year. Now we’re getting somewhere.

The mod pack consists of three levels that use GPU accelerated PhysX. The rest of the game is left unchanged. You can run these levels without GPU acceleration, but they’re much slower.

The three levels are HeatRay, Lighthouse and Tornado. Guess what the PhysX does in Tornado?

Ben and I played HeatRay together (aw, cute). First the PhysX enabled level with GPU acceleration turned off, then with it turned on and then the standard level that doesn’t use any GPU accelerated PhysX at all.

Turning the PhysX acceleration on made a huge difference, we both agreed. The game was much faster, much more playable. The most noticeable PhysX effect was hail falling from the sky, and lots of it. You could blow up signs in the level but the hail was by far the most noticeable part. Note that I said noticeable, not desirable.


See all of the white pellets? Yeah, that's what PhysX got us in UT3.

Playing the normal version of the HeatRay map was far more fun for both of us. The hail was distracting. Each of the hundreds of pellets hit the ground and bounced off in a physically accurate manner, but in doing so it sounded like I was running through a tunnel full of bead curtains suspended from the ceiling. Not to mention the visual distraction of tons of pellets hitting the ground all of the time. Ben and I both liked the level without the hail. The point of the hail? Not to make the level cooler, but rather to truly stress the PPU/GPU - particles are one of the most difficult things to do on the CPU thanks but work very well on the GPU. This wasn’t a fun level, this was a benchmark.

Tornado was the turning point for us. As the name implies, there’s a giant tornado flying through this capture the flag level. The tornado is physically accurate, if you shoot rockets at it, they fly around and get sucked into the funnel or redirected depending on their angle of incidence. It’s neat.

The tornado sucks up everything around it but if you’re looking to relive Wizard of Oz fantasies I’ve got bad news: you are immune from its sucking power. You just stay on the ground and lose health. Great.

Ben’s take on the tornado level? “It was neat”. I agreed. Not compelling enough for me to tattoo PhysX on my roided up mousing-arm, but the most impressive thing we’d seen thus far.

    I haven't checked the benchmark numbers yet, but you list Forceware 185's on the NV side, and Cat 8.12's on the AMD side.
    Any reason why you are using brand new drivers for one side and 4 set old drivers on the other?
    Sure, NV might not support a card on older drivers etc, but it's more useful to see newest driver vs newest driver, since there are performance changes from 8.12's to 9.3's in various games, but it just seems silly to use 3+ month old drivers which have been superseded by 3 revisions already. Would anyone buy a brand new card and then use drivers from 3~4 months ago?

    The setup chart has been updated. We utilized previous test results from the HD4870 with the 8.12 HotFix drivers. The HD 4890 results were with the 9.4 beta drivers. I just went through a complete retest of the HD4870 with the 9.3 drivers and just started with the 9.4 betas on the AMD 790FX and Intel P45/X58 platforms. Except for a slight performance improvement in Crysis Warhead on the P45/X58 systems, the 9.3 drivers offered zero performance improvements over the 8.12 HotFix. The 9.3 drivers do offer a few updated CF profiles and improved video playback performance, but that is it.

    "the 9.3 drivers offered zero performance improvements over the 8.12 HotFix."

    Not only that, but if you read the ATI forums, a lot of people have been having MAJOR problems with 9.2 & 9.3. I downloaded 9.1 for my new 4870 build and have had no problems.

    Now now, ati doesn't have any driver problems, so don't you DARE go spreading that lie. You hear me ?
    Hundreds of red roosters here have NEVER had a driver problem with their ati cards.
    Shame shame.

    Stop posting, seriously, you're stupidity is causing me pain.

    Another personal attacker without a single counterpoint to the many lies I've exposed. Good job brainwashed fool.

    Thanx - good to know.

    The Inq or The Reg is pretty adamant about the 275 being there just to spoil the 4890 launch, but never really in stores, and reviewers getting special hi-specs, hi-overclock hand by nVidia instead of the manufacturers.

    Did your card come from an anonymous purchase, or was it a special review sample ?
  • Gary Key - Thursday, April 2, 2009 - link

    We mentioned in the article that we received a review sample from NVIDIA. The clock speeds are the same as the retail cards that should start arriving later next week with widespread availability around the week of 4/13. Our retail review samples will arrive early next week.

    As we stated several times in the article, this is a hard launch for AMD and yet another paper launch for NVIDIA, although according to the board partners the GTX275 is coming quickly this time around.

    I also feel confused and somewhat misled by the conclusion that the GTX275 is "the marginal leader at this new price point of $250".

    That conclusion doesn't seem true outside of resolutions of 2560x (30" monitor). Plus, $250 cards aren't even targeted or seriously considered for gaming at that resolution.

    I came up with a different conclusion after thoroughly reading this review:

    At the $250 price point and 1680x or 1920x gaming resolutions (where these cards primarily matter), the 4890 holds the majority performance advantage. However, at 2560x the GTX275 performs a bit better than the 4890. Realistically though, at 2560x or on 30+" displays, you're best served by a dual GPU or SLI/Xfire solution.

    Something's fishy about the reviewers' conclusion.
