Borderlands 2 Framerate Drop with PhysX High

post #1 of 9
Thread Starter 
Hello all,

I recently started to research Borderlands 2 performance issues, while not completely unplayable I'd like to find out solution for random framerate drops.

I have i7 2600k@4GHz with SLI GTX 570. I tried different combinations (SLI,dedicate one 570 to physx, CPU to physx).

Whenever there are too many particles from weapons,dirt and other stuff I get framerate like 35 - 45 instead of expected 60fps stable.

Resolution 2560x1440
My settings are all maxed out except :
View distance: High (3/4)
Ambient occlusion: Off (to get few frames)
Depth of field :Off (I don't like that distant blur)


Any idea? Ini tweak?

Of course, I can go with PhysX to low and I will never have a problem, but I'd expect from UT3 engine 60fps.

VRAM bottleneck, perhaps?

Hi, well my VRAM consumption is like 680 MB at peak. I am not even sure if physx care about VRAM but I think it has to do something with bad optimization. People with GTX 680 + Dedicated PhysX reported same problem.

Yeah dude, my GTX 680's in SLI also have frame rate dips with high PhysX. Nvidia are on to it I think, they posted a tweet.

Yeah, I've read something similar from Nvidia but now when you confirm it then I am kinda irritated. I don't think I need upgrade yet to handle 5 years engine with tweaks to run 60 at least.

I'd say that same problem would be with Quad SLI with GTX 690.

Just don't tell me that testers didn't detect this issue.

My hope then lies that Gearbox will come up with some major tech patch or clever guys (no irony) from Nvidia will find the way how to improve it with their drivers.

Same issue in gtx 690 quad sli. They had better get moving on tis.

Hi zkalra, so I guess there is no performance issues with my HW, I don't plan to upgrade yet (later on I plan to buy same card you have if not some breakthrough technology will come in following years).
Right now I play with Low PhysX but I feel I miss something.

PhysX isn't really optimized too well.

Its mainly a driver/optimisation issue - people with all kinds of rigs are facing a myriad of issues. You are definitely missing a lot with Physx on low though but should wait for the next patch before making any kind of upgrade plans.
