Nvidia 80 drivers and dual core processing.

[rockman]

When I heard a rumor of the Nvidia 80 drivers adding support for dual core I decided to see what kind of difference, if any, in frame rates they offer. I decided I would check my frame rates using counter strike source mostly because I didn’t think the results would be so interesting, I was wrong.

The Rig:
AMD 4400+ X2 @ 2915mhz
Redline 265mhz @ 2225
2 x 6800U @ 450/1100

I'm not sure what all settings and tweaks I have running in counter strike although I made sure clock settings and options remained the same for both tests. I also made sure the background applications running were the same during both runs.

FPS on the 78.01 = 134fps
FPS on the beta 81.26 = 180fps :slobber:

After a saw these results I quickly loaded up 3dmark05 and actually saw a loss of frame rates going between single and dual core processing, so apparently it is specific on the application that you are running. I did not let this get me down and I tried Aquamark to see if that would show an increase and it did.

This is my X2 running using the /onecpu flag in the boot.ini

There is my X2 running as it should.

Keep in mind I did not run "bench" settings so I'm not trying to show off results, only trying to show off these new drivers and the possible potential using a dual core CPU. I hope to see results from other dual core users. :D

Where did you get the Betas

hmm looks like nvidia's current SLI implementation has alot of cpu overhead? that's my best guess

well until now that is :)

yeah, these mutli threaded drivers are going to Kick so much ATI ass, and I am an ATI fanboy.

[Pomme]

So... Does the application itself need to be coded multithreaded, in order to benifit from the multicore-drivers from nvidia ? I guess so ?

I put those driver , but with them , i cannot overclock even with one MHz.... what is wrong , i am usin Riva 15.7

you can get them at guru3d.com

I doesnt find ant deference between 78 and 80 in 3dmark with X2 4800+ and SLI 7800GTXs...

Yes these drivers are like ones they had earlier, they fail the "test" no matter what mhz you are trying for. You need to use rivatuner to disable that test and then use apply at start-up if you want to keep them set that way. In rivatuner under power user: "RivaTuner 2.0 RC 15.6 \ Overclocking \ Global" set "DisableClockTest" to 1

Unfortunately I found the same result in 3dmark.

awesome dirvers !
it should be great to see how they perform with a 840EE

What resolution, AA and AF settings were those CS tests done at?

There were also quite a few water tweaks used. I play the game to have the biggest advantage as possible and giving up some of the eye candy was needed. The water tweaks really boost up frame rates because it doesn't reflect anything, really helps out on the Aztec map. The settings remained the same for both runs though.

most likley crapily....as the 840 preforms :rolleyes: heh j/k but intel needs to step up there dual cores

[GAR]

81.26 drivers are sweet, but they have a shadow bug on BF2...other than that, i cannot wait for the final and polished release of these drivers, took my aquamark from 97 to 120...thats some serious gain.

go back and re-read the first post. He said he already tried it in 3DMark apps, and the driver(at this point at least) is application specific, not just a general threading for dual-core.

These should do nicley with my O/C'd 3800X2 and a 7800GTX
