FYI - Batman demo to download with PhysX...

[Talonman]

I agree...

Yep, in the end what we see is what matters. Which is why it's in Nvidia's best interest to let everyone see what they're missing and judge for themselves. Right now, a lot of the "PhysX is crap" people have never even seen the thing in action for themselves and are basing their opinion on youtube videos or just lashing out in retaliation for being excluded.

From what i have seen im not really missing out.

The problem is the tool that is PhysX is not being used to its advantage & is like a company advertising how good a steam roller is at fattening things by rolling over ants, when its capable of much more but people only see the ants being flattened all the time.

Only the demo game CellFactor made me go wow with the physics, everything after seems pale & not worth my investment

Yeah it's a whole different vibe if you already have a supported card. Then you just feel like you're getting something more for free that you can disable if you don't like it. Just like the AO option in the drivers or supersampling support. All minor in isolation but together they add up. But I can see people not letting that influence a buying decision. I'm just glad I'm able to play around with this stuff and see it in action for myself, whether it's lame or not.

I just gave it a quick try, for me at the first fight with physx settings off I had 90~100 fps at the first fight with physx off and on normal around 50~60 FPS and same at high with no visuable difference.

Oh and those intro vids are annoying (nvidia logo etc), remove them by clearing this section in DefaultEngine.ini:

[FullScreenMovie]
+StartupMovies=esrb
+StartupMovies=baa_logo_run_v5_h264
+StartupMovies=UTlogo
+StartupMovies=nvidia
+StartupMovies=Legal
+StartupMovies=Install

Always brings me a smile when I find this comment in all the unreal3 engine games engine ini:

; mostly copied from 2k4
[Engine.DemoRecDriver]

ie, copied from Unreal Tournament 2004. So much junk code left there that's not used or removed.

EDIT: Now here's a funny and weird one, applying 4x AA with physx off I get a FPS boost over no AA, FPS climbed from 90~100 FPS to 98~135 FPS! lol And yes AA is working nicely. Must be the first game I've tested that both looked better and ran faster after applying AA.

Any1 else experiencing the same?

Hey, anyone tried the method which was used to let ATi cards smoothly run physx in the Star Tales Benchmark?

-----------
go to the game dir/Engine/Config/BaseGame.ini
find
[Engine.Worldinfo]
MaxPhysicsSubsteps=5 modified to 1
bEnableChanceOfPhysicsChunkOverride=FALSE modified to TRUE
------------
wait for good news

Nvidia's performance is very interesting these days. Their driver team seems to be really concentrating on performance improvements for high resolution / 4xAA scenarios. Meanwhile, at times I have found that lower resolution AA performance has suffered. A PERFECT example of this is Left 4 Dead.

In addition, Far Cry 2 uses the DX10.1 code path which makes ATI's cards that much more efficient when AA is turned on.

4X AA is my favorite selection.

Due to on the page where I originally typed it, we were still saying things like:

and



I believe at that time, we were proceeding on lack of info, and my statement didn't seem to hold much weight with the boys.

Now in light of some actual CPU PhysX FPS numbers surfacing, it's looking to be more correct.

With the apparent huge performance difference we are seeing, I am now thinking it is more than just an CPU optimization issue. I think it's more of a hardware limitation issue.

GPU's are just way better at PhysX. (Sorry if the 3 lines in my quote took up too much screen space.)
I will try not to let it happin again.

fine,would you show us some 1920x1200 VeryHigh 16xCSAA screenshoots with HighPhysX setting. thx.

4X AA is my favorite selection.

I want to add I use a rather old 182.47 driver though (complains about it when I start the game but in reality the newer drivers perform worse for me, at least in other games) and UT3 for example takes a huge hit by AA (a bit bigger than most games), it's weird cuz they both use the same engine. I also tested AA2x and AA8x and found AA4x to be the optimal, AA2x wasn't faster at all, it was at least as fast, if not even slightly slower by like 3~5 FPS in avg and 8x was slower as well but not that much, stayed often 100~115 but sometimes had drops to 85~90.

[mao5]

hey, Talonman, how's my physx fps on my shabby 4850CF and Q6600?

[mao5]

nobody dares show the CPU PhysX screenshoots with fraps on ? I dare, haha!

[Talonman]

Looks good... What res is that?

And when you say 16x CSAA, you do realize that isin't an in game setting correct? It does have 16XQ, and 16X. What did you select?
Do you also have Ambient Occlusion on or off? I keep mine on even thouigh there is a performance hit involved. I does look better.



What PhysX level are you running?

Post up you options screen like mine, and I will match it exactly.

[mao5]

What PhysX level are you running?

1680x1050 VeryHigh set physxlevel to 1 in ini file, you can turn off AA in game option, and force 16xCSAA from foreware control panel, before Batman demo, nv fans always force AA from cp in UE3 games

[Talonman]

Well heck, I don't know what ini file your talking about...

My BmEngine text file is currently at level 2?

PercentUnoccludedRequeries=0.125
MaxOcclusionPixelsFraction=0.001
MinTextureDensity=0.000000
IdealTextureDensity=13.000000
MaxTextureDensity=55.000000
PhysXLevel=2
bPhysXuseGRB=False
PhysXgrbSpacing=10.000000

But rest assured, I cut the level of PhysX down from High, and run at a lower res than 1920x1200, and turn Ambient Occlusion back off, you don't think I can beat 40, 56, and 91 FPS?

[mao5]

fine, show me the difference between level1 and level2, pls.

you have 3GPU running together, so why cut the level down and lower the resolution? come on, show us the screenshoots at 1920x1200 16xQA VeryHigh and Level 2 PhysX, thx.

[Talonman]

I still am not sure exactly how to set 16xQA...

yes it dropped to 22 minimum with frps i had the fraps fps going for lvl1, lvl2 was low i didnt bother with fraps since it lagged

XS users are not the same as other forums and i do have the fastest single gpu card and a good oc on the cpu

I can tell you zanzabar was getting 22 minimum with Level 1 PhysX...

Setting your CPU to level 2 PhysX, as I enjoy, would hurt your performance bad, even at your lower res.

Check this promo out when the game is released...

I do mean 16xQ or 16x in your game video option, btw, anything wrong with my level 2?( I adjust level in the setting menu

[mao5]

I do see some difference between level 1 and 2, some sences fps actually raised after killed the monster.

[RPGWiZaRD]

Is it only me or do I see jaggies in the screens? I thought even the 4x ingame setting looked smoother.

[Talonman]

+1

So how is it he is running PhysX level 2 on his CPU, but getting better FPS than the rest of the ATI boys?

I have a feeling there is more 'customization' in his files than what meets the eye.

Too many instruction with odd laughs on every post. Is it the Joker?

I am unconvinced he is actually running level 2 PhysX on his Q6600, and getting 129 FPS. (Even at his 1680x1050 res)

So what is his secret? (How do the rest of the ATI boys get level 2 PhysX with 16x CSAA on their CPU, with 100 FPS?)

Do tell....

how about bet 1million $ on my 129fps?

Instead of betting, answer the question...

When did ATi cards support 16xCSAA？

[Talonman]

No answer again...

odd!

What do you boys think about his posted results?

[mao5]

other ati boys can enter the first cave near the cell get the same fps with 4850CF at level 2

[mao5]

No answer again...

odd!

answer what? Ati cards don't suppert 16xCSAA, how would you let me answer?
