Hail!

OK, so you guys are THE best ppl to help with problems like these, right?
So let's see what we can do.

I'm Alex, a dedicated gamer focused on FO3. This is the best game I have tried out so far, and I mean it. Wanna play it for years. And I mean it. Seriously.

What have I been doing with my game:
I have a retail copy of FO3 and it is patched to 1.7
I play the game for 3 years now, out of that one year+ with mods.
During that time, I have been trying out many mods (all of them from Nexus.com but one), changing my load order every now and then - yes, all the time, sometimes even every day. Now I have my choice of mods (more or less).
I made some 5+ reinstals of my FO3 so far.
I use medium quality details.
Every time I started the game over (some 20 times so far), I would change many of my stats via the Console, and my character's carry weight is usually 2000. I always carry loads of guns.
I have all 8 hotheys mapped with guns.
I am using the program called Game Booster for better performance.
I am using FOMM and FO3 edit (edit, master update and master restore) and GFWL disabler.

Problems so far:
Half a year ago, my FO 3 suddenly started lagging beyond any playability. Before that, it was running OK, but I had CTDs during gameplay, including the really weird ones happening at the same place in the worldspace. The CTDs also included those when fighting a ton of enemies using the FWE Increased spawns. So, I have realized that I had to update all of my drivers, which I did and now my FO3 is running most of the time, but the gameplay smoothness is still faaar away from the old days - and those were the days, I tell ya: even with some 20 NPC, everyone (and everything) shooting all barrels, explosions, limbs flying all over the place and it almost wasn't lagging at all. Yes, it was running OK.
And now?
What a pile of misery! Sweet Lord Jesus! This makes me wanna jump otta my own skin, man!
Now, every time I play, after some half an hour the game play gradually starts stuttering and eventually starts to lag like hell. Saving the game (with the cursor stuttering in the menu, of course), exiting the game and starting the game again (I use ONLY FOMM - in last two months boosted via the Game Booster) solves the problem, but in some half an hour here we go again!
AND, that's when the game runs, friends. All the damn time, I have CTD on continue so that I have to load an earlier save and the newest one after that. AND NOW - that's today - I gotta CTD on almost every load of whichever save and also CTD on fast travel. So, do I go play Pacman? Nope, that just ain't gonna happen, right? So, let's see to it.
