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.

So he just told you why he's gettting NVidia, and the little red fanboy in you couldn't stand it. You recommend taking steps that void the warranty, but why should you care - then you blabber about a 4850, but he already noted the 260 - and finally you let the last word in you could barely bring your red rooster self to say GTS250 - as in you might as well get it.... if you have to - 'cept he was already looking above that.You red ragers just have to spew about your crap card to people who already seemingly decided they don't want it. Why is that ?
You gonna offer him red cuda, red physx, red vreveal, red badaboom, red forced game profiles, red forced dual gpu ? ANY OF THAT ?
NO -
you tell him to HACK a red piece of crap to make it reasonable. LOL
What a shame.
Hey, maybe he can hack the buzzing fan on it , too ?

What the hell are you talking about?Im not a fan boy of any of those big companies that don't give a shit about me.
I have used both nvidia and ATI, and both produce great graphics cards.
I had a 8800gtx before my current 4870, and i had and athlon x2 6400+ before my current core i7 920.I go with whoever has the product with the best price.

No, you are a fanboy and you are exposed. Deal with it.helldrell666 - Monday, April 6, 2009 - link
It's you, who the fanboy is.You're trying hard to show the advantages of nvidia cards over the ATI cards, and guess what, you fail.And i don't give a rat ass about CUDA.Im a gamer, and what matters to me is the card's gaming performance and the features that enhance my my gaming experience "which is what 99.9% of who buy those cards care for", Like physx, which is a true con for nvidia cards.But physx isn't supported on most games, and the physx effects that nvidia is trying to promote can be easily processed on a decent sub 300$ cpu by enahncing the on cpu physx performance via a driver/software that could utilize all cpu cores and utiliz the cpu processing power in a better way.
Ohh wait.ATI has DX10.1 and tessellation which nvidia doesn't have, and thanks to your nvidia, we didn't get much games that support
DX10.1, and we didn't get any game that supports tessellation which is a geometry accelerating technique that can accelerate geometry processing by up to 4 times using the same amount of floating points aka. processing power.If tessellation, which is included in ATI cards APIs since the Hd2000 series days, was used in those demanding games like crysis and stalker, we would've been able to play them using sub 300$ graphics solutions.Put aside the DX10.1 features like the aa enhancement.....and the GRS color detector that allows the gpu to use more accurate color degree for a texel using a more advanced texturing algorithm compared to the tri/bi-linear buffering teqnique used in nvidia's illegal uncompleted DX10 API.

rofl - the long list of your imaginary hatreds against nvidia - you FREAK fanboy.The problem being, that just like some lying retard, you blame ati's epic failure with tessalation on who ? ROFL NVIDIA.
Sorry bub, you're another one who is INSANE.
You won't face what IS - you want something that isn't - wasn't - or won't be - so keep on WHINING forever, looney tuner.
In the mean time, nvidia users outnumber you, enjoy the large amount of added benefits, and don't have a 2 billion dollar loss hanging over their heads - with a company that might collapse in bankruptcy - and lose support of the already problematci drivers.
You bought the wrong thing, now you have a hundred could be would be if and an's and garbage can complaints that have nothing to do with reality and how it actually is.
Fantasy red rooster fanboy.
LOL - it's amazing.

Freak fanboy......? Hatred....? Are you serious...or ....?I don't hate any company because i have no reason to.I blame nvidia for not allowing those few developed games companies to include those great features in these very few modern demanding games.
Accelerating physx processing using the gpu is a great idea, but is it worth it?
Is the cpu realy unable to keep up with the gpu in games due to it's slow physx processing ability?
Are those primitive physx effects realy that heavy n a modern quad core cpu?
These are questions that you should ask yourself before trolling for the idea.
And i have to remind you that ATI has coded Havok physx effects in
OPEN-CL programming language, which in case you don't know, is standard langauage compared to nvidia CUDA, which is based on some kind of c programming codes.
Talking about the drivers, i haven't had problems with my 4870 on MY Vista 64bit OS, compared to my old 8800gtx that almost brought me a heart attack.
As for your beloved nvidia, we need nvidia as much as we need AMD and INTEL to keep the competetition alive, which in its turn will keep innovations going and adjust the prices.
Ohh... and thanx to the red camp, we can get a decent graphics card for less than 300$.so have some respect for them.
as for you, i wonder how old you are, cuz you don't seem to have a mature logic.
tamalero - Monday, April 20, 2009 - link
dont worry, this guy clearly as mental issues, a nvidia paid troll.SiliconDoc - Tuesday, April 7, 2009 - link
Yeah, sure. Just like any red rooster, you never had a problem with ati drivers, but nvidia drove you nearly to a heart attack, but I have problems with logic or detecting a red rooster fanboy blabberer ! ROFLDude, you keep digging your own hole deeper.
Then you try the immature assault - another losing proposition.
YOU'RE WHINING about nvidia and yeah, you do blame them, and after going on like a lunatic about wanting offload to the cpu, you admit it might not work - yes I read your asinine quadcore offload blabberings, too, and your bloody ragging about nvidia "not letting" your insane fantasy occur - purportedly to advantage ati (not like you're banking on intel graphics).
So red rooster, keep crowing, and never face the reality that is, and carry that chip for all your imiginary grievances of what should be or, what you say could have been.
In the mean time, know you are marked, and I know who and what you are, and I'm sure you'll have further whining and wailing about what nvidia did or didn't do for ati. LOL
roflmao
Logic ? ROFLMAO
" I, almost had a heart attack " said the sissy. lol " But I'm an objective person with logic ". roflmao

Wow what a stunning pile of crap i've just read.ATI's can fold, guess what it's downloaded via CCC.
ATI has open source cloth physx, stream and avivo which pisses all over that trash nvidia call 'purevideo' or whatever.
But best of all, you can ACTUALLY BUY A 4890 whereas the 275 only exists in the Nvidia fanbois tiny little green with envy minds.

If you haven't noticed, SiliconDoc is basically ignored in all his responses. Be wise and do that same. He'll eventually kill himself :)
