Hybrid Physx - Borderlands 2 experiences

[BaldManBDC]

Hi all,

Just looking for some feedback, I got a GTX 650 for a dedicated Physx card with my 7970.

I have managed to get it going with the Hybridiz utility, I can see I am getting load on the card and Physx works some what better than when using my i7 920.

I get around 45-70 FPS in normal situations, low Physx.

As soon as I get into heavy Physx gameplay I get spikes/FPS drops.


When I enable the GTX650 ,I can see on the GTX650 Usage in MSI afterburner it is spiking up and down all over the place (which I would assume is causeing the ingame spikes) between 0 and about 50% load.

Anyone else out there running Hybrid Physx in borderlands 2, if so what are your experiences with it so far?

I have tried Physx 9.11 and 9.12 both seem about the same, 9.12 maybe being slightly better.

People experience these problems on different configurations, including Ati only ones. So its probably not physx. I also have these spikes but i dont think its because of hybrid config, as, for instance, you could still have physx effects that wouldnt cause lag, from shooting in soil or smth. I set physx on high though (dont think you should stick with low having a 650). In most places its 70(and up to 120) fps that slightly goes down for 10-20 fps during heavy firefights, but certain places, like when you have to get to claptraps ship and kill some 'knight' is lagging very much.

Im running Hybrid on a 7970 with a 460 for PhysX. The game was perfectly smooth for me until i got to the area where Captain Flynt is/Claptraps boat as mentioned above (That section seems really bad for it). Then it sort of became a bit stuttery. I notice that afterburner shows the load on the 7970 dropping off so its probably game/drivers that need a bit of tweaking.

Im using this method http://www.*****.com/graphic-cards/2...85-solved.html

And playing in 6120x1200 everything maxed... Framerate is 50-60fps when it doesnt go all stuttery.

Edit: Seems like the people on that forum are also having the same issue.

[thatguy91]

Maybe the update will fix that

Do you use Lucid MVP at all (2.1.115a)? I know Borderlands isn't in the list, but try adding it. I added it and it worked fine for me. I set it so the logo appears at the bottom right hand corner of the screen then disappears after a few seconds. The Intel GPU seems to run quite well at 1500Mhz (used auto OC feature in the bios), only slightly reduced the preset OC voltage. No issues with heat.

I realise that it won't fix the problem, but I use the logic that if it's there, and works, might as well use it. You paid for the integrated GPU afterall!

Thanks for the feedback Shagula, pretty much exactly what I am experienceing.

Hope there is a fix for it soon, as when it comes to FPS I hate to play them without a minimum of 60FPS, so its back to Low physx for me atm, and 130 bucks wasted.

What should we use for the mix Ati/Nvidia-for-PhysX (600series)? apart of driver of course

Physx software, Hybridiz.exe.

not really working well in borderlands 2 atm though.

Hybridiz.exe? Not PhysX-Mod?

[BaldManBDC]

Sorry I was on my phone earlier and couldn't elaborate.

Here are the steps I have followed, and have loading on my GPU.

1) Install the latest WHQL driver and the latest PhysX software 9.12.013
2) Run Hybridiz.exe patch as admin.
3) move the following files to a different folder
cudart.dll
cudart32_30_9.dll
cudart32_41_22.dll
PhysXCooking.dll
PhysXCore.dll
PhysXDevice.dll
PhysXLoader.dll

Which Nvidia card do you have for PhysX?

Which gain did you experience in Batman?

I have a GTX650 as per the original post.

I dont have batman.

[Luca T]

I have your same configuration and I was considering a 640 (because I found a fanless model with no additional pin) but reading here and in other forum I'm not sure if buy 640 or 650

A guy with a 3930k and a crossfire of 7970 have lower performance with a 640 dedicated than with PhysX managed by cpu

[Solid_State]

Very good hybridized experience it is.

1080P PhysX on high the frame rate never dips below 30fps.

I have seen 70% GPU load on the GT430 while playing.

[minsterkermy]

so i'm using a 7870 with a GT 620 in a hybrid configuration and I'm seeing decent framerates, rarely dropping below 30fps. Should be mentioned that just enabling PhysX will drop your framerates dramatically, and has been mentioned in various forums - an example with physx disabled in Batman AC i can get roughly 130fps on the 7870, cut that in half with physx on medium, and then again with physx on high. in game is different, this is just using the benchmark.

I had purchased a GT 640, thinking the higher cuda cores and memory bandwidth might help, but using the same drivers and everything basically just swapping out the cards, I couldn't get the 640 to work with anything BUT borderlands 2 and fluidmark, where the 620 works with every physx title i have. even then the performance difference is nominal.

i dunno, if you can someone can get the 640 working with everything that'd be awesome.. as for now, I figured i'd just stick with the 620 which i reciently overclocked and seems to have squeezed a few more fps out of it when using fluidmark....

[BaldManBDC]

Interesting, could be a 6 series issue, as from what ive read , the 640 and 650 are real 6 series, where as the lower are rebranded chips.

[Noisiv]

yes, GT 620 is akin to GT 430/530, ie. GF108, ie Fermi

[mitzi76]

i found running another card as physx wasnt worth it. game still had fps drops...

but if you try a game like mafia2 that's another matter.

at least that's just what I felt...(was a 580 with a 640).

Agreed, Borderlands is not workig to well with a dedicated physx card.

the FPS drops are to harsh to make it worth it. Hopefully somone can get a fix happening.

[GenClaymore]

Yea I tried BL2 with a 9800GT in my PCIE 2.0 4x slot and it stuttered like crazy and dropped fps as well. IT even happen on phsyx GPU low. So I had to remove it and undo the hybrid phsyx gpu. Interesting enough doing medium on my HD7950 it self with the cpu doing it ran better then it did with the 9800GT as the Phsyx gpu.

Funny enough I did try Sacred 2 GPU phsyx with it and it did the same thing. Which was odd.

Hallo. I just set up the latest Hybridiz.exe mod. I have Sapphire HD7970OC 3GB GPU@1150/VRAM@7000 and ASUS EN465GTX 1GB on stock clocks. Dont know yet about the functionality in games but the "Physx Fluids by Kenneth Bugeja.exe" as well as "PhysX FluidMark 1.5.0" say they use Physx GPU which is confirmed by GPU-Z 0.6.6, showing about 50% GPU load while benching. IT WORKS!!! Both between 60 and 70 FPS ;o)

you are not getting large dips to around 25-30 fps in intensive physx action?

[Fox2232]

1st: BL2 has a lot of stuff is calculated via CPU even when PhysX compatible card (read nVidia) is present in system.
2nd: True 6xx nV cards have intentionally crippled compute power compared to 4xx/5xx series and invested more into rendering performance.

This makes low end GT640 (65W, 384shaders, 128bit, gddr3) weaker in PhysX than GT550Ti(110W, 192shaders, 192bit, gddr5) at roughly same price. But GT640 has only 1/2 of power requirements in comparison.

If I decided to get nV card for PhysX it would not be anything below GTX 560 Ti which is 200W card (40nm). And question is: "Is it worth it?" To have few flying particles and bit of liquid blob at price of 200W card?

From information which are publicly known (1st/2nd point). PhysX is going to be in future more CPU optimized than now as average GTX 6xx card kind of struggles with PhysX tasks. And with that in mind I see no point in buying separate PhysX card.

Next thing is that SDK 3.0 has no more x87 joke instructions and uses ?SSE? *joke* by default. And It automates multi-core threading properly.
nV probably decided to improve overall opinion on what PhysX should have been and maybe, just maybe they will put it back on right track some time in 2013/2014.

Yo, wazz up! Not sure what you mean by "dip". Sorry, my bad, my English is not that slangy. Can you please describe it around? By the way, I found out that Hybridiz.exe somehow ruined the nVidia driver and the windows registry so that after the PC turned off and on again, there was an error.43 in HW Manager by the NVIDIA GeForce GTX 465 and the yellow exclamation mark triangle - saying the hardware stopped working. I tried to remove all nV drivers, files, windows registry keys, everything. I even removed the card from the case, then started the PC up to the full desktop boot (about 10 sec. btw.), then turn it of again, pushed the card back in. Installed the nV 306.97 and PhysX 9.12.0613. Guess what? After the restart the MO****F***ING yellow exclam. mark again! Now, a smart ass guy (me), used Acronis Backup&Recovery 11 and created an Acronis backup image before started experimenting. So I re-imaged the PC (took about 8 minutes to unmelt the 12GB TIB file), installed latest Ati drivers and there I was, at the very beginning of experimenting again. Let you know later...

Hasta la vista

[GeorgettaCZ]

Well, I think I know now what you meant by dips. I just created a video posted here http://youtu.be/AoIBsGbtp7E. There is fullscreen record of Fluidmark 1.5.0 and all other information about HW/SW setup and overclocks. Though this video does not show it well enough, during some more testing I could see waves of drops, or as you call it, dips of framerates. The highest was still around 60 fps and average around 42 fps but each 20..30 sec. it looked like somebody pulled the handbrake and the fps dropped down to around 23-25 fps for 3-7 sec. And it is not the HDD doing something else then it should. The benchmarks are on the Corsair Force GT SDD. I am going to try the BL2. And NO, I did not buy that game. I downloaded it from some torrent...

Chat ya later!

[GeorgettaCZ]

F**K ME, ITS HERE AGAIN! After an uninstallation and necessary restart, there is error mesage with yellow triangle exclam. mark in HW Manager by my NVIDIA Geforce GTX465 Code 43 Windows has stopped this device because it has reported problems Any advice..? Or is it just me with this mess?
