Fallout 3: General FPS drop/ lag/ stutter

[archer]

Hi,

I’v have resurrected Fallout 3 after 10 Years to run into issues I have never had with this or the other Fallout games nor Skyrim. I encounter strange lags/ stutter/ FPS drops everywhere. In Megaton I cannot make a single step withhout stuttering. Outside’s the same but not so strong but annoying enough. I have limited FPS to 30 for research. FPS dropping occurs whenever I look around, especially looking to buildings or other mesh structures. The ENBoost FPS meter jumps from 30 to 5-10 for a short time. For example standing in Springvale and looking around without moving is all I have to do to get my FPS dropping.

My Rig:

    Windows 7 x64 and/ or Window 10 x64 (two 850EVO SSD boot drives). Problem occurs on both systems
    Intel Core i5 7600K Kaby Lake
    32GB RAM
    EVGA GTX 980Ti/ 6GB
    LG Ultrawiede 3840 x 1600


Software:

    Fallout 3 GOTY GOG (non-Steam version)
    Mod Organizer 2 (installed mods stored on SSD drive)


For modding I follow Kelmychs guide (http://wiki.step-project.com/User:Kelmych/Fallout3)
(A big THANKS to Kelmych)


Mods/ Addons:

    ENBoost v0.322 (boost only, no GFX tweaks)
    FOSE v1.3 Beta 2
    Ogg Vorbis Libraries v3
    OneTweak for Fallout 3 v2.0.1.1
    Fallout Stutter Remover v4.1.36 + Fallout Stutter Remover dll für Windows 7 v4.1.26 + Fallout 3 My Way - Resources (FSR .ini by Gamerpoets)

UI-Mods from Kelmych’s guide from DarN UI to UIO. Nothing more.

I have no idea, any help would be great. Thank you.
