Huge Performance Jump by setting GPU as my physx Processor (Single GPU NO SLI)

[No Soy Pls]

Yes. Like +30 FPS. From 40 FPS to 70 FPS in intense particle situations with Medium PhysX.
This is HUUGE considering I played for 100 hrs at Low PhysX.
Love BL2!

I already get great FPS with an Phenom X3 8750 @ 2.4 ghz, 4 gb of ddr2 ram, and my Radeon HD 6670, but I just went into my options, and I had already set my physx to medium a few weeks back, however I no longer have the option to change it, for some odd reason. Maybe something with my Catalyst Control Center is causing it?

@Markula:

If it won't let you change it in-game, are you able to change it through the WillowEngine.ini located in My Documents\My Games\Borderlands 2\WillowGame\Config ?

Under "[SystemSettings]"
PhysXLevel=2 (High).
Try lowering the value?

Welp, I completely didn't read his final sentence (I stopped at "reason") :p

It's time for a CPU upgrade for you. Low PhysX will do the job on the CPU; so if you have a slow processor this is precisely why. Otherwise, medium PhysX will -always- be slower.

High PhysX then pretty much demands a high end dedicated graphics card to function without tanking hard.

Well CPU is always slower for me too, and I have an i7-4770 and a GTX760

I don't really see how, unless you have a lot of bloat on your computer eating up on your processor, because I too run a i7-4770(K) and it's always faster than having it run on my graphics cards (Titan w/ dedicated 480).

Anyways, just clearing that up, GPU PhysX will be faster only in two situations: you either running a dedicated GPU for it, relieving the rendering card of the load, or you have a slow processor/bloated OS ;)

I have an i5-4670K. Medium PhysX on CPU gave me 40 FPS in intense situations. When PhysX actually gets triggered.

Medium PhysX on GPU gives me 70 FPS in most intense situations and normally it is 120 FPS.

I only have 1 GTX 780. How exactly is CPU faster? I think you are wrong.

[Random_Gamer_12345]

How do you set the physx to use gpu or cpu? I only have the regular option of low/med/high settings.. dunno what it's using for it though.

Low = CPU only, no particle or fluid effects
Medium = GPU accelerated, small amount of particles and fluids (blood, corrosive, slag)
High = GPU accelerated, LOTS and LOTS of particles and fluids, recommend using additional dedicated card for this

NVIDIA released a comparison video back when the game was about to be released, it's a few years old but every bit as valid: https://www.youtube.com/watch?v=EWFkDrKvBRU

Naah.. Changing just the PhysX settings from Low to Medium didnt help.. AT ALL.

I had to go to NVidia Control panel and under 3D Settings there is a Configure Surround/PhysX.. i changed the PhysX processor there to my GPU.. thats when I started getting very good performance.

Nah, not wrong, but if you're actually doing stuff like, blowing up everything with Unkempt Harolds, Norfleets and stuff, then expect the framerate to tank even on bleeding edge computers, it's a problem with the game really and will happen regardless of PhysX setting, though Low and Medium will always be faster in that regard.

I play on OP8 mostly and sometimes there's so much stuff going on that I get 15 fps myself in some situations, and i'm running my 4770K at 4.7 GHz, the processor load can be as high as 95% sometimes on my particular case.

The Unkempt Harold is #1 public enemy in that aspect, just check out my processor load:

http://i.imgur.com/d0QVo0Y.jpg

it's so high, my graphics card throttles down to lower clocks, and there's simply no faster gaming processor than this right now. I do have hyperthreading off, because it allows me to hit higher clock speeds and enhance the IPC a little further beyond, so you know.

Turn PhysX all the way down to low, and that insane CPU saturation will simply be gone; since it won't render any particles or fluid, put it on Medium and it'll be less bad...

Honestly.. your pics don't show that many particles..
There are way more particles at Boom Bewm.
But I think it must be the FireRate of your unkept harold. When I get the harold I will test for myself..
But I really don't expect FPS it to tank all that much.

I just fought 4 skeletons shocking me 2 times per sec along with a bunch of Knights and those Fire Arrow guys shooting everywhere...
My framerate was fine..

May be it is the NVidia Card being able to do physX better than non Nvidia cards..
BL2 actually worked with NVidia for the PhysX.

What GPU do you have?

[No Soy Pls]

Ursprünglich geschrieben von ZM Dr. Dro:

GTX Titan @ 1215/3726 + GTX 480 @ 850/2005; the pictures don't show it because there's not that many particles, that's why FPS is above 60, try something like the Wildlife Preserve and I just have to quit and turn the thing all the way down to try it again. :/

Damn the Titan?!
I have i5-4670K & gtx 780
Nothing is overclocked.
I will try and report back. But it will be a while coz.. I am doing Tiny Tina DLC now.

What about Thousand Cuts? (Huge performance killer...)

[No Soy Pls]

Ursprünglich geschrieben von ZM Dr. Dro:

GTX Titan @ 1215/3726 (usual clocks, it's on my 3506MHz memory profile on the pictures, I use 3506 when I'm going above 1.25 GHz for benching) + GTX 480 @ 850/2005; the pictures don't show it because there's not that many particles, that's why FPS is above 60, try something like the Wildlife Preserve and I just have to quit and turn the thing all the way down to try it again.

It's a beast of a computer, and i'm pretty proud of it, but even a monster has its own shortcomings :)

Are you sure your Mobo isnt a Bottleneck?

Thanks for the info Dr, Dro :)

I had physx on high to start with, but the amount of particles on screen (via my shotgun especially) really cluttered things up for me. There was some slight stuttering as well with physx on high (when the screen was filled with particles).. not game-breaking, but noticeable. Also, the game kept crashing in Opportunity and I heard that having physx on high was the culprit, so I switched it to low for that reason especially.

I have a 4 year old Dell XPS 8100, i5 3.2ghz cpu, 6gb ram, upgraded with new psu and NVIDIA GeForce GTX 650 Ti BOOST graphics card. It runs at 1920x1080, with all settings on high, and runs quite well for an old machine (with new gfx as noted above).

I just did a quick test in Tiny Tina dlc, at the beginning.. on low, medium then high physx. I had vsync on and fps capped at 60 for the test (no need for more imo, I just turned it back down to 50 fps for my regular gameplay). All physx settings had 50-60fps at all times during the first wave of skeletons at the Unassuming Dock, so not bad at all. I will keep physx at medium setting though, as too many particles can unsight me in my battles :)

You guys do realize that clockspeed means next to nothing when talking about processors, right?

PhysX is a NVIDIA exclusive and is unavailable for all AMD (and legacy ATI) GPUs.

PhysX works perfect with my AMD Radeon HD 7870, set using the ingame Video Options menu, but probably all software, not on GPU itself. I've tested it on all 3 settings and it does what it's designed to do.

Here is the list of all Physx games on the PC,

http://physxinfo.com/index.php?p=gam&f=pc

the ones with a green check mark are the few (23 so far) that can use GPU accelerated Physx.

When using different architectures, yes, when using the same one, the higher clock CPU will *always* be faster.

HD 7870 can't run PhysX, it's all done in CPU, and it's extremely slow when you have plenty of stuff going on, so it's all either Low/off for AMD hardware.

LoL - I'm maxed out on everything with PhysX on High and occasionally it'll drop to 45 FPS with lots of action. I set it for 60 FPS no VSYNC.
