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.

Update: I guess Anand was making his updates while I was making my post, so the "marginal leader at this new price point of $250" line is gone and the Final Words actually now reflect my own personal conclusion above.Anand Lal Shimpi - Thursday, April 2, 2009 - link
I've updated the conclusion, we agree :)-A

You agree now that NVidia has moved their driver to the 2650 rez to win, since for months on end, you WHINED about NVidia not winning at the highest rez, even though it took everyting lower.So of COURSE, now is the time to claim 2650 doesn't matter much, and suddenly ROOT for RED at lower resolutions.
It Nvidia screws you out of cards again, I certainly won't be surprised, because you definitely deserve it.
Thanks anyway for changing Derek's 6 month plus long mindset where only the highest resolution mattered, as he had been ranting and red raving how wonderful they were.
That is EXACTLY WHY his brain FARTED, and he declared NVidia the top dog - it's how he's been doing it for MONTHS.
So good job there, you BONEHEAD - you finally caught the bias, just when the red rooster cards FAILED at that resolution.
Look in the mirror - DUMMY - maybe you can figure it out.

Check the article again. Anand edited it and it is now very clear and concise.7Enigma - Thursday, April 2, 2009 - link
Bah, internet lag. Ya got there first.... :)sublifer - Thursday, April 2, 2009 - link
As I predicted elsewhere, they probably should have named this new card the GTX 281. In almost every single benchmark and resolution it beats the 280. In one case it even beat the 285 somehow./Gripe
That said, Go AMD! I wanna check other sites and see if they benched with the card highly over-clocked. One site got 950 core and 1150 memory easily but they didn't include it on the graphs :(

Hey guys, I just wanted to chime in with a few fixes:1) I believe Derek used the beta Catalyst driver that ATI gave us with the 4890, not the 8.12 hotfix. I updated the table to reflect this.
2) Power consumption data is now in the article as well, 2nd to last page.
3) I've also updated the conclusion to better reflect the data. What Derek was trying to say is that the GTX 275 vs. 4890 is more of a wash at 2560 x 1600, which it is. At lower than 2560 x 1600 resolutions, the 4890 is the clear winner, losing only a single test.
Thank you for all the responses :)
Take care,
Anand

Thank you Anand for the update and the article changes. I think that will quell most of the comments so far (mine included).Could you possibly comment on the temps posted earlier in the comments section? My question is whether there are significant changes with the fan/heatsink between the stock 4870 and the 4890. The idle and load temps of the 4890 are much lower, especially when the higher frequency is taken into consideration.
Also a request to describe the differences between the 4890 and the 4870 (several comments allude to a respin that would account for the higher clocks, lower temp, different die size).
Thank you again for all of your hard work (both of you).

Yeah, I would also second a closer comparison between RV790 and RV770, or at least mention it. It's got new power phases, different VRM (7-phase vs 5-phase respectively), slightly redesigned core (AT did mention this) and features a revised HS/F.VooDooAddict - Thursday, April 2, 2009 - link
I was very happy to see the PhysX details. I'd started worrying I might be missing out with my 4870. It's clear now that I'm not missing out on PhysX, but might be missing out on some great encoding performance wiht CUDA.I'll be looking forward to your SLI / Crossfire followup. Hoping to see some details about peformance with ultra high Anti-Aliasing that's only available with SLI/Crossfire. I used to run Two 4850s and enjoyed the high-end Edge Antialiasing. Unfortunetly the pair of 4850's were a too much heat in a tiny shuttle case so I had to switch out to a 4870.
Your review reinforced something that I'd been feeling about the 4800s. There isn't much to complain about when running 1920x1200 or lower with modest AA. They seem well positioned for most gamers out there. For those out there with 30" screens (or lusting after them, like myself)... while the GTX280/285 has a solid edge, one really needs SLI/Crossfire to drive 30" well.
