FYI - Batman demo to download with PhysX...

so vids are done, exept for a fighting (thats coming soon)

smoke - http://tinypic.com/player.php?v=20pyqev&s=3
sparks+cape - http://tinypic.com/player.php?v=2urv5dz&s=3
blur - http://tinypic.com/player.php?v=242g3r7&s=3
tiles - http://tinypic.com/player.php?v=nn8l52&s=3

yah tiles work with forced physX to 1 in config but the banners in the big room dont work now


edit here is a small fight seen with the paper, cape, and spit aticals/shock waves (i think that its spit or they are really dirty and im dusting them
http://tinypic.com/player.php?v=2us7bcj&s=3


all files were made with fraps all settings maxed, 1600x1200, no AA, forced physX mode 1, 720 be unlocked 3.6ghz, stock 4890, 1440mhz 7-7-7-18 ram. fraps lags a little with cashing, u can see were it went every 20sec or so in the fight

Nice! Goes to show you this all can be done using the CPU. Something repeated in this thread several times already. However, you have to reconfigure the game's .ini file(s) (or whatever else is involved) to do it. Goes to show you that CPU physics isn't properly utilized for this game. :p:

Could you provide a step by step instructions on how this is done?

go to "Documents\Eidos\Batman Arkham Asylum Demo\BmGame\Config"

then open UserEngine.ini

next change "PhysXLevel=0" to "PhysXLevel=1", u can also set it to 2 but it just seams to add alot of paper and that makes it lagg a little while adding nothing to the game

Wow, simple enough :p:
It makes absolutely no sense why CPU physics wasn't optimized with this game so that all you have to do is select how you want physics done from within the game. This is a nice find no doubt but I have to question what would have been if they properly coded this game were we don't have to tweak a .ini file via physx instead of the engine itself.

:up:

the cpu is broken in it IMO, with physX it uses 2 threads without its on 1 so the total physX package should work on 4 threads

Ok, I think there's a lot of confusion here. Why do you guys need to edit the ini directly? If I disable GPU PhysX the game still lets me select the option but gives a warning on performance. At those settings I get 50-60fps with GPU PhysX and 8-12fps with CPU PhysX. This is on an e8400@3.6.

i was chilling at 80fps normal and 25-30 with physX, but i couldent change it untill i edited the ini

So the in-game option only appeared for you after editing the ini manually? Wonder if they're going to change that for the full game. Thanks for checking this out, think this is the first game where would could directly compare CPU and GPU PhysX.

Then it is indeed broken. Why would anyone need to show GPU/CPU results when cpu physx only uses one thread :rofl:
Had the engine itself properly utilized physics on the CPU w/o the need of physx we would be able to choose how we want to use in game physx IMO.

I would like to see an ATI member run at these settings, to see if the CPU can indeed give the same performance as the GPU in this game...

Post some screen shots with fraps, take V-Sync off, and I will do the same tonight after work. :up:

I still am of the mindset that while some level PhysX may be able to process on a CPU, we should be careful not to imply that it can match it's performance when running on a GPU. If you run with PhysX on High, and 4X AA, at 1920x1200, I still believe the CPU will lose real bad. If we are willing to throw performance out the window, yes a CPU can run PhysX too, but this is XtremesyStems right? We never throw raw performance out the window do we?

It's OK if you have more CPU than me... I won't hold it against you. :)

How did you get it up to 80fps? I can't get it past 60fps no matter what, looks like it's the same thing for Talonman based on those numbers he posted. V-sync's off so it seems like the engine itself is locked to 60fps. :confused:

100 hrz monitor :)

Monitor refresh has nothing to do with fps unless vsync is enabled. And it isn't. Is anybody else seeing > 60fps in this game? I tried overclocking the CPU too and lowering the resolution but still nothing. Very curious, wonder if I'm memory bandwidth limited.

Man-O...

I wanted to see how much faster I would run with V-Sync off.

I have a 60hz display too, but that never stopped me before from getting more than 60FPS. (With V-Sync off)

with UT3 max refresh is typically the cap on max fps even without vsink

I just found this...

http://forums.tweakguides.com/showth...?t=5700&page=6

"In terms of tweaking, the UT3 structure has changed slightly but all the relevant .ini files are found under \Documents and Settings\User\My Documents\My Games\Unreal Tournament 3 Demo\UTGame\Config. The main config files are UTEngine.ini for general engine graphics/audio variables, UTGame.ini for player-based variables, and UTInput.ini for bindings.

The -nointro switch doesn't seem to work, so skipping the intro movies involves (as Jonas has pointed out) going to \Program Files\Unreal Tournament 3 Demo\UTGame\Movies and renaming the following files: Copyright_PC.bik, EpicLogo.bik, Intel_Duo_logo.bik, MidwayLogo.bik, Nvidia_PC.bik, UE3_logo.bik.

Apparently people have uncapped the 60FPS limit by changing the bSmoothFrameRate to =false in the UTEngine.ini.

You can access the console with ~ key, and the console commands are similar to UT2004. STAT FPS for example shows your framerate - try the other commands on page 12 of the UT2004 Guide.

I'll obviously look into this in much greater detail once I start the UT3 guide in the next day or so. There's a lot of tweaking potential in the game, and I have a feeling it will be quite popular among the UT crowd."

Or the next post..

Actually the FPS cap is at 62 FPS at default:

[Engine.GameEngine]
bSmoothFrameRate=TRUE
MinSmoothedFrameRate=22
MaxSmoothedFrameRate=62
bClearAnimSetLinkupCachesOnLoadMap=TRUE

Ah, thanks you're right. Just tried UT3 and Mass Effect and same thing there too :up:

NV can fool some of the people but not all of the people.


Any chance of looking into some other UT3 engine PhysX... games to see if the same can be done.

If it can be done in this game one should be able to do it in other unreal 3 based games. However, this is the only game that I know of right now.

Once again I don't think PhysX is all that great.

Found it!! :)

http://img141.imageshack.us/img141/8636/answere.jpg

Going to try changing my numbers...

The only thing I changed was MaxSmoothedFrameRate=100.000000, and set V-Sync to OFF.

[Engine.GameEngine]
bSmoothFrameRate=TRUE
MinSmoothedFrameRate=24.000000
MaxSmoothedFrameRate=100.000000

Works like a charm! :)

Sweet. No help for me though. 2560*1600 + PhysX is taxing my card pretty good as it is. It's too bad Nvidia has no incentive to optimize PhysX on the CPU. Havok isn't helping either, they need to provide more competition.

True that!! :p:

I am hitting 100 FPS in spots, so i'm sure I could get more if need be.

So far 100 FPS is fine for me, especially with a 60Hz display.

Some other people have been trying out PhysX on the CPU through the in-game menu & are getting as low as 12 fps.

Are you sure your fps did not dip into the 12's ?
