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.

One is an open, one is not.Jesus christ.
The fact you have to pay extra on top of the card prices to use these features is a no go. You start to lose value, thus negating the effect these "features" have.
p.s ATI have similar features to nvidia, what they have is nothing new.

Did you see a charge for ambient occlusion ?Here you are "clucky clucky cluck cluck !"
Red rooster, the LIARS crew.

One ? I count for or five. I never had to pay extra outside card cost for PhysX, did you ?You see, you people will just lie your yappers off.
Yeah ati has PhysX - it's own. ROFLMAO
Look, just jump around and cluck and flap the rooster wings and eat some chickseed, you all can believe eachothers LIES. Have a happy lie fest, dude.

Personally while you bring up good points I'd much, much, MUCH rather have the thorough explanation of CUDA and PHYSX and the relevance thereof, they gave us than power, heat and overclocking numbers you can get at dozens of other reviews. The former is insight, the latter just legwork.joos2000 - Thursday, April 2, 2009 - link
I really like to soft shadows you get in the corners with the new AO features in nVidia's drivers. Very neat.dryloch - Thursday, April 2, 2009 - link
I had a 4850 that I bought at launch. I was very excited when ATI released their Video Convertor app. I spent days trying to make that produce watchable video. Then I realized that every website that tested it had the same result. They released a broken POS and have yet to fix it. I did not appreciate them treating me like that so when I replaced the card I switched out to Nvidia. I have gone back and forth but this time I think I will stick with Nvidia for a while.duploxxx - Thursday, April 2, 2009 - link
and by buying Nvidia you already knew that you didn't have POS so in the end you have the same result, except for the fact that the 48xx series really had a true performance advantage with that price range so your rebranded replacement just gave you 1) additional cost and 2) really 0 added value, so your grass is a bit to green.....Exar3342 - Thursday, April 2, 2009 - link
"0 added value"? Really? He didn't have a GPU video converter that worked on his ATI card, and now he DOES have a working program with his Nvidia card. Sounds like added value to me. He gets the same performance, pretty much the same price, and working software. Not a bad deal...z3R0C00L - Thursday, April 2, 2009 - link
The GPU converted that comes with nVIDIA is horrible (better than ATi's though).I use Cyberlink PowerDirector 7 Ultra which supports both CUDA and Stream. Worth mentioning that Stream is faster.

Is the 30$ pricetag of badaboom included in the "pretty much the same price"? If it isn't, then actually there is no added value. You have a converter (value, well only if your goal is to put video's on your ipod and it's worth 30$ to you to do it faster) but you have to pay for it extra. The only thing the nvidia card provides is the ability to accelerate that program, you don't actually get the program.
