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.

LOL - antoher hidden red rooster bias uncovered...Umm... look, when there's a new ati card, there's no talking about crunching down on former ati cards - OK ? That just is NOT allowed.
" No mention of the death of the HD 4850X2 as the HD4890 trashes the power consumption, price, availability, speed and OC-ability "
Dude, not allowed !
PS- Don't mention how this card is going to smash the "4870" "profit" "flagship" - gee now just don't talk about it - don't mention it - look, there's no rooster crying in fps gaming, ok ?

Props to ATi for delivering a very compelling product. I admit I've always been an Nvidia fan, and I'll generally forgive them a single generational performance loss to ATi, but I've recommended ATi products recently to friends due to their resurgent desirability.That being said, am I the only one who detects a subtle but distinct underlying disdain for Nvidia? So they tried to market the hell out of you - so what? They are trying to sell cards here. Why the surprise that sales and marketing people are trying to do exactly what they're paid to do? Congrats for being smart enough to see it for what it is, but jeers for making an issue of it as if its some kind of new tactic. Has AMD/ATi never done the same?
CUDA and PhysX are compelling, but I agree not a good reason to overcome a significant gap between Nvidia and ATi at a comparable price point. You clearly agree, but it seems like what little praise you offer is begrudging in the extreme.
Nvidia has definitely acted in bad form in a number of ways throughout this very lengthy generation of hardware. However, you guys are journalists and in my opinion should make a more concerted effort to leave the vitriol and sensationalism at the door, regardless of who it is that is being reviewed. That kind of emotional reaction, personal opinion, irritation, etc is better served for your blog posts than a review article.
Love the site, keep up the good work. Nobodys perfect.

Yeah thanks for noticing, too. It been going on a long time. Notice how now, suddenly when ati doesn't have 2560 sewn up - it doesn't matter anymore ... LOLOf course the "brilliiantly unbiased" reviewers will claim they did a poll on monitor resolution useage, and therefore sudenyl came to their conclusion about $2,000.00 monitor users, when they tiddled and taddled for years about 10 bucks between framerates and nvidia ati - and chose ati for the 10 bucks difference.
Yep, 10 bucks matters, but $1,700.00 difference for a monitor doesn't matter until they take a poll. Now they didn't say it, but they will - wait it's coming...
Just like I kept pointing out when they raved about ati taking the 30" resolution and not much if anything else, that declaring it the winner wasn't right. Now of course, when ati isn't winning the 30 rez - yes, well, they finally caught on. No bias here ! Nothing to notice, pure professionalism, and hatred of cuda and physx for it's lack of ability to run on ati cards is fully justified, and should offer NO advantage to nvidia when making a purchase decision ! LOL
OMG ! they're like GONERZ man.

Best review so far. And nice cards BTW, they are both worth it, but i like the 4890 betterFunny thing is that GTX 275 > GTX 280.
But my guess is that GTX 280 benefits more from overclocking.

Because of my PC's location I am concerned with idle power, and purchase based on that if other specs and price are even comparable. Peak power doesn't matter as long as it's within the capability of my 800W PSU.I bought an ATI HD4850 last year because it idled significantly lower than the 4870, and it would run everything in sight. A great card. The Nvidia GTX 260 and 280 had even better performance vs idle power ratios but were way too expensive at the time.
So I think Nvidia takes the laurels now with the GTX 275. 30W less (!) than the HD 4890 at idle, with essentially the same performance. If I were shopping now it would be a VERY easy choice.
I really hope ATI can get their idle power down too. They need to pay more attention to throttling back or downpowering circuits that aren't needed in 2D modes.

Use the radeon bios editor to edit the 2d profile and then downclock your gpu frequencies.OCedHrt - Friday, April 3, 2009 - link
The power consumption on the 4890 really interests me. While it uses more than 275 at idle, it uses less under load. Also, it is a significant drop from the 4870 which is a slower card.bobvodka - Friday, April 3, 2009 - link
So, on the charge of drivers; I've gone from recently having a GT8800GTX 512Meg to a HD4870X2 2gig and if anything I've seen stability improvements between the two. Or to put it another way NV drivers were bluescreening my Vista install when I was doing nothing more than using my TV card and it was crashing in a DirectDraw DLL. Nice.Not to say AMD hasn't had issues; trying to use hardware acceleration with any bluray play back resulted in a bluescreen due to the gpu going into an infinite loop. Nice. Fortunately, unlike the DDraw error above, I could at least turn off hardware acceleration (and honestly, with an i7 it's not like I needed it).
So, stability wise it's a wash.
As for the memory usage complaints about CCC;
Unless it is running it is NOT taking up physical memory. Like many things in the windows world it might load something into the background but this is quickly paged out and doesn't live in ram. Even if it does living in ram for a short period of time being inactive it will be paged out as soon as memory presure requires it. The simple fact is unused ram is wasted ram; this is why I'm glad Vista uses 10gig of my 12 for cache when it isn't needed for anything else, it speeds up the system.
Cuda.. well, the idea is nice and I like the idea but as mentioned in the article unless you have cross vendor support it isn't as useful as it could be. OpenCL and, for games, DX11's compute shaders are going to make life intresting for both Cuda and AMD's option. I will say this much; I suspect you'll get better performance from NV, AMD and indeed Larrabee when it appears by going 'to the metal' with them but as with many things in the software world you have to trade something for speed.
Now, PhysX.. well, this one is even more fun (and I guess it effects Cuda as well to a degree). Right now, with Vista, you can't run more than one vendor's gfx card in your system at once due to how WDDM1.0 works; so it's AMD or NV and that's your choice. With Win7 however the rules change slight and you'll be able to run, with WDDM1.1 drivers, cards from both vendors at once. Right away this paints an intresting landscape for those intrested; if you want an AMD card but also want some PhysX hardware power than you'll be able to slide in a 'cheap' NV series card to use for that reason (or indeed if you have an old series 8 laying about use that if the driver supports it).
Of course, with Havoc going OpenCL and being free for games which retail for <$10 (iirc) this is probably going to be much of a muchness in the end, but it's an intresting idea at least.

Except you can run 2 nvidia cards, one for gaming, the other for physx.... so red fanboys are sol."Right now, with Vista, you can't run more than one vendor's gfx card in your system at once due to how WDDM1.0 works; so it's AMD or NV and that's your choice. "
WRONG, it's TWO nvidia or just ONE ati. Hello - you knew it - but you didn't say it that way - makes ati look bad, and we just cannot have that here....

The hell are you talking about? Crossfire works in vista just fine.
