Very low FPS at seemingly random times

[nocthesis]

Ok, I know I'm probably testing my luck here given the age of F3 and the fact a lot of folks have moved on to TTW, but I'm desperate. I have a GTX 970 which has no trouble running Fallout 4 at 60fps - heck, even NV runs fairly smoothly. Yet Fallout 3 plays.. horribly. I've played the game before and I can't remember it being this bad. Just look at certain buildings at certain times cuts my fps in half - and I can't get above 40fps during fight sequences.

 

So far I've tried:

- messing around with my ini's

- installing on an ssd

- decompressing BSA files

- disabling mods

- tweaking my NVIDIA settings

- messing around with the stutter remover.

 

I'm not sure if I've missed something - but has anybody else had any success getting this game to play without the horrible lagging and stuttering?

 

Thanks, I'd really appreciate any help.

Have a similiar problem, with only a slightly stronger graphics card known as the rx 580 4gb of vram. The cpu is ryzen 5 quad core 3.2 gigahertz more than enough power. The issue under my regards must be related to multi cores. I dont think iNumHWThreads=2 is good for performace since my computer has 4 cores and 8 threads. My fps is similiar to the post above around 40 to 75, with 40 being the norm when facing open world areas. I tried changing the number of threads to 4 but i get a pink screen. I also edited the ini to use alot more ram for the game under certain settings. My fallout goty folder is 30 gb with 20 gb of mods i have aroubd 170 mods no crashes just bad performance for my desktop's standards. The fan isnt even working hard it is very quite, it works much harder with two other much newer games by the names of brick rigs and beamng drive while those run 60 to 100 fps on ultra.So ultimately there is no bootleg part of my setup and it is all related to the game.

Fallout 3 was never designed to run on more than 2 cores in a multicore CPU. Also, it was never designed to run on a laptop with a graphics chip.

 

I honestly don't believe you have 170 mods active since the game was designed to run with a theoretical limit of 155 mods. The practical limit is between 120 and 130 mods.

 

Unless you have made the game Large Address Aware, it makes no difference how much RAM you have, the game will only use a maximum of 2GB. Even then, you can only use a maximum of 4GB.

 

Since most people accept the default install location of "Program Files", this also causes a problem with certain mods not running because of the Windows User Account Control.

Seems as if I found a fix - I had installed MO2 on a separate drive to my Fallout 3 installation.

Yes it is theoretical, however look at my mod list it is over the limit: 171 mods active according to mod organizer well subtract it by 5 you get 166 11 mods higher and the game runs fine just with frames that the gpu I have are unacceptable, heck it does even work hard at all, it runs fallout 4 on high at 60+ fps

MO2 is on program files for me under a modding category, I also have a separate hard drive holding other data. Do you recommend installing mod organizer on the external since the non-external has MO2? Also I have my mods installed under Fallout 3 GOTY/DATA/F3mods instead of the base directory

Just to add something here. You don't want to have a back up copy of the game any where on your hard drives. The engine will try to access that back up copy and this will cause you issues in the actual game you're playing. Also, with FSR you wan't to make sure you're using the proper dll file for your system.

 

From what I've read, the mod limit recommended for FO3 peaks at 145 mods. In my experience, I find the game behaves best with 100 or less mods. Any more and strange things start to happen. Running MMM in my load order, I find around 85 mods to be ideal. You can get around your max load order, by utilizing a bash patch. In fact, I recommend bashing your mods. It's silly not to.

 

FYI: Just because people are telling you to do this and that to your games, doesn't mean it's going to work for you. Depends on your set up and rig. Sometimes doing less is better. ^^

Remove Fook.You cant use that and FWE together.

[Deleted21304489User]

That's hilarious. How the heck do you even get the game started using both FWE and FOOK? I'd love to see the conflict report on that. LOL !!
