FPS decreases as I play

I have an issue that has plagued my New vegas for ages and no one has known how to fix it. My FPS is at a rock solid 60 when I load my save but, after 10-15 mins of gameplay I start to notice it slowing down, after 40 mins it is as low as 35fps which is unplayable to me. When I exit the game and load it up again it's back at 60FPS again. I had heard it was a DoF related issue but I have disabled any DoF mods and disabled it in the game settings, If anyone can provide any help it would be much appreciated, even if just suggesting which type of mods could cause this, Thank you.

In case anyone was wondering my specs are:

 

Intel i-5 [email protected]

8GB DDR3 RAM

XFX R7970 DD 3GB GDDR5 VRAM

 

That's probably all that's important for this king of issue. Though i'm 99% sure that it's not a hardware thing.

It's a problem a lot of systems have although your case seems more severe than normal. Have you tried purging the cell buffers in game once your framerate drops? Type "pcb" into console and see if that helps your framerate.

I have tried PCB, I even installed an auto purge mod but nothing works. It's getting annoying now.

It sounds hard to believe, but re-using the same savegame slots does this (in fact josh sawyer has commented on it, its a GameBryo issue).

 

Always create a new slot when you save, and just delete the old ones now and again.

 

I always, without fail create new saves, I don't think I've ever overwritten one.

yeh didnt fix mine either.. making new saves and deleting all others still results in a frame drop from the 90's to the 70's after playing for a small amount of time.. 20 mins or less sometimes..

 

Sometimes seems like its after entering a new area or after talking to someone then leaving the are not sure if theres any correlation
