Advanced Physx in Metro last light causing MASSIVE frame drops

[Josh-Sweeny]

I recently got metro last light and because i have a gtx 780 i naturally decided to max out all the graphics settings. I started playing it for about 15 minutes and it was going fine at around 60fps when my suddenly my fps dropped to 20 and getting as low as 12. I started lowering the graphics settings turning anti aliasing completely off. this didn't do much so i decided to put all graphics settings down and also physx and my frame rate jumped from where it was 20 previously to 90. After a bit of trial and error i found out physx was the problem and when i have everything maxed out apart from physx then i get 70fps. Does physx actually make a 50fps difference in this game?

Nvidia Physx can cause a great FPS drop in tons of games. People even get low FPS in Borderlands 2 which is a less graphic intensive game with your graphics card maxed out with Physx and still gets 10 FPS.

It depends on the game and screen resolution.

Metro LL is quite demanding on hardware to begin with and then adding all this PhysX to the mix makes the card work even harder.

Please make sure that your Nvida control panel is set to use the video card and not cpu. If it is, I would just lower that setting and enjoy more playable frame rates.

Some users report using an extra card for PhysX makes a noticeable difference as well since it frees up resources for the main card.

As has been said, Metro LL is very hard on the system, but a sudden FPS drop like that makes me think the CPU might be overheating, try checking its temperatures under load.

Glad I found this. I couldn't figure out why I was getting smooth 60 FPS then suddenly a drop to 15ish for no reason. Turned off Advanced PhysX and it's immediately fixed.

MSI GTX760 Twin Frozr OC- Very High settings.

I just got Metro Last Light because it was on sale. Just like you, the game play was fine at first but quickly deteriorated. I checked Metro game web site and it recommends an i-5 or even i-7. Fortunately someone has pointed out that the PhyX driver with the video driver is out-dated. I installed the latest PhyX driver and now it works perfectly with frame rate > 60 fps.
Go to http://www.nvidia.com/object/physx-9.13.0725-driver.html
and download the latest PhyX driver. It is not part of the video driver package for some reason. If it still doesn't work, turn off the Advanced PhyX option in Metro.

Why PhysX isn't included in the drivers is beyond me. You'd think the new GeForce Experience app would let you know that it can be added on or something. Now I have an answer as to why the PhysX box was unchecked in GPU-Z. I assumed it was included and something was wrong. Excited to try it out after work now. Such an awesome game!

Thanks for this.

Thank you so much!!!!!!! I have been looking for a solution to my random FPS drops in certain games also, I can't believe this isn't with Geforce. Now I feel like I've been cheated the past few months, how crazy. I went from drops to 15 FPS in Metro LL and now I am crispy running 100 on average. I'm going to check all my other physX related games right now, thanks again !
