borderlands 2 resolution "undefined"

[Avinoam73]

it started two days ago: i go to the video options menu, choose my native resolution 1920x1080p, saves it, the game looks like it runs on 1080p resolution but on the resolution menu it shows that the resolution is "undefined". i don'y know why this happens, but all i know is that this might be the cause to the FPS dips i get lately when looking at certain directions (which started not long ago as well) no matter what resolution, what setting (low-ultra). i've tried deleting all the .ini files in the game's documents, i've uninstalled it and re-installed it (which of corse had me downloading the game again) and still nothing.
specs:
NP9150
7970m
i7-3610QM
8GB ram
windows 8.1
drivers: 14.7 beta drivers
thanks for the help!!!

Wait. You installed the DLC and then this happened?

This started happening right after you installed the dlc huh?
It might not solve the issue, but if you haven't done so already, I'd verify the game files. Could be something didn't actually get downloaded and installed correctly. Although I highly doubt this would give you such a huge dip in fps, it's worth a try.
Right click your game in the steam library, select properties, select the local files tab and look for something like "verify game cache integrity".

This also took me a while to recall, but most discrete AMD mobile GPUs feature an horrible thing called "Enduro technology". Simply put, it decides literally on the fly which GPU has to run the current app, even if the app is running already, to save energy. This obviously goes to the expense of your hardware...
If you can (since you can't on some laptops), try disabling Enduro, and also force the CCC to run the game with the 7970m if you haven't done so already.

the thing is this: a long time ago, (about 3 weeks) my laptop started doing me trouble. after a long (,long loooong) troubleshooting i found out it was a problem my AC adapter was causing: it was slightly torn, and it downclocked my GPU. i ordered a new adapter from the internet but the shipping was very long so i played some of my games on my dad's laptop ( acer v5 with an i5-4500u and an intel 4400). i had to lower the resolution and settings of course, but i've managed to play borderlands 2 (including the DLC) on 60 FPS on the lowest settings and on a very low res (can't remember which one). the minute i got my new adapter, and started playing on MY laptop (7970m, i7-3610QM) it started happening.

i've put borderlands 2 on high performance on the CCC and that means the 7970m will run it. i verified the integrity of cache: "one failed file was found and will be accired"- changed nothing.

Still do disable Enduro technology if you can. Really, it usually adds more headaches than advantages...

Otherwise it's just an issue with the 7970m. I've seen a ton of reports telling the game doesn't run well on the card, as load stays around 60%...

thanks. how do i disable enduro?

I recall having an option into either the BIOS or the CCC on a friend's laptop, but it was an old model right after Enduro technology was released the first time.
If you don't have such an option, things are going to be a bit annoying, as your only option is downgrading to the most recent driver not supporting it.

That's only possible if your laptop manufacturer isn't locking out driver updates, as some lock you to update any driver only through their website. You need to check first if you can actually install any driver freely, otherwise you're pretty much locked in having it enabled.
