Fallout 3 runs like garbage on PC - recommend fixes?

For the record I also recall me and my friends having issues with the steam version of this game and NV back in 2012, and to the current day with a new cutting edge gaming rig I cant believe it still has problems. So far ive dealt with a shoddy frame rate, which was fixed by capping the FPS in the config settings but it then fucked up the speed of the entire game. NPC dialogue didnt match their speech/body language, everyting just went like twice as fast so ive set it to the original setting and now i have the frame stutter again.

Is there any mods to fix this? I'm determined to replay this classic because i have so much love and nostalgia for it but if it's going to have headache-inducing frame rate stutter and endless bugs I'd rather drop it and play something else that's better optimised for current gen PC. It's a shame because the whole reason i bought a good PC was to play all the 360-era games I used to play but couldnt in peace because my parents were too busy lingering around and calling me a loser for playing video games.

I'm running the game on Ryzen 5 7500F, Radeon RX 7800 XT with 32GB RAM.

Any tips? Thanks in advance.
