Oblivion Lags on a Good Computer

[CostlyBody]

Hello, people. So basically, I have Oblivion: Game of the Year edition, the Russian version, and recently it started to lag a lot . I thought it was because I have over 25 different mods :/ . It used to run smoothly just over 60 FPS but now it runs under 30 :\ . I tried uninstalling the mods, but it only ran like two frames faster . I tried putting it on very low graphics quality (originally it ran at very high with V-sync on) but it wouldn't even start . I tried installing Operation Optimization (an Oblivion mod that keeps the meshes of the game the same, but optimizes them) and it really helped get me up to 40-50 FPS :3 , until I see an NPC, and it lowers to about 20 FPS >:c . It is really annoying me, and it's game-breaking :c .

My specs are:
Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601)

Running the game on very low quality
Defraging my hard drive using RegCure Pro

Games my computer can run:

Skyrim on High
Star Wars: The Force Unleashed II on highest
Both Bethesda's Fallouts on Ultra High

Did you try reinstalling the game?

Did you try reinstalling the game?

Yes. Didn't do anything, except for deleting my savegame.

Also, my computer is a laptop.

Tried playing the game with every combination of cores enabled.

Tried playing the game with every compability mode.

Download MSI afterburner and check clocks/GPU usage while playing it.

it would help to know exactly which model GPU you got. It's possible you've finally hit the VRAM limit

Neither of Geforce 5xx series cards got less than 1 GB of VRAM, and there's no way to hit that limit with a 6 year old game.

NVIDIA GeForce GT 540M with 1GB/2GB DDR3 VRAM.

Also, Oblivion crashes everytime when I exit, which is not that bad, but a slight annoyance. I am downloading two mods for that. One is called Fast Exit. The other is called Window Earle's Oblivion Crash Prevention System

I can't download MSI AfterBurner. It stops everytime at about 20 MBs downloaded.
