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.

Must be tough trying to write a balanced review when you clearly favour one side of the equation. Seriously, you tow NV's line without hesitation, including soon to be extinct physx, a reviewer relieased card, and unreleased drivers at the time of your review. And here's the kicker; you ignore the OC potential of AMD's new card, which as you know, is one of it's major selling points.Could you possibly bend over any further for NV? Obviously you are perfectly willing to do so. F'n frauds

What?! Did you even read the article? They specifically say they cannot really endorse PhysX or CUDA and note the lack of support in any games. I think you're the one towing a line here.SiliconDoc - Monday, April 6, 2009 - link
The red fanboys have to chime in with insanities so the reviewers can claim they're fair because "both sides complain".Yes, red rooster whiner never read the article, because if he had he would remember the line that neither overclocked well, and that overclocking would come in a future review ( in other words, they were rushed again, or got a chum card and knew it - whatever ).
So, they didn't ignore it , they failed on execution - and delayed it for later, so they say.
Yeah, red rooster boy didn't read.

jesus dude, you have a strong persecution complex right?its like "ohh noes, they're going against my beloved nvidia, I MUST STOP THEM AT ALL COSTS".
I wonder how much nvidia pays you? ( if not, you're sad.. )

That's interesting, not a single counterpoint, just two whining personal attacks.Better luck next time - keep flapping those red rooster wings.
(You don't have any decent couinterpoints to the truth, do you flapper ? )
Sometimes things are so out of hand someone has to say it - I'm still waiting for the logical rebuttals - but you don't have any, neither does anyone else.

All these guys talking about how irrelevant physx and how not so many games use it don't get it. The power of physx is bringing the full strength of those GPU's to bear on everyday apps like CS4 or Badaboom video encoding. I used to think it was kind of gimmicky myself until I bought the "very" inexpensive badaboom encoder and wow, how awesome was that! I forgot all about the games.Rhino2 - Monday, April 13, 2009 - link
You forgot all about gaming because you can encode video faster? I guess we are just 2 different people. I don't think I've ever needed to encode a video for my ipod in 60 seconds or less, but I do play a lot of games.z3R0C00L - Thursday, April 2, 2009 - link
You're talking about CUDA not Physx.Physx is useless as HavokFX will replace it as a standard through OpenCL.
sbuckler - Thursday, April 2, 2009 - link
No physx has the market, HavokFX is currently demoing what physx did 2 years ago.What will happen is the moment HavokFX becomes anything approaching a threat nvidia will port Physx to OpenCL and kill it.
As far as ATI users are concerned the end result is the same - you'll be able to use physics acceleration on your card.

You do realize that Havok Physics are used in more games than Physx right (including all the source engine based games)?And that Diablo 3 makes use of Havok Physics right? Just thought I'd mention that to give you time to change your conclusion.
