So yesterday i noticed i got a random patch on steam for fallout 3, and after not playing it for a week (had guests) i exitedly decided to finish the game today and what do you know, not only did the game boot up with the settings all fucked, wrong resolution, now setting to high instead of ultra, but it simply couldn't go past the play button, instantly crashing. I did the ini thing it didn't work, i did the "rename Fallout3Launcher.exe" thing, well while it did work for a moment, in game, i found myself performing super poorly (while before i used to get a solid 60 at all times) now dipping to 40s at times, everything looking super fucked, getting tons more audio delay glitches etc etc. So id like to know, is this a known issue ? What happened ? And can i fix it ?

EDIT: Solution found!

The problem came from the video card not being detected in the launcher, what i did was actually simple:

• go to display settings
• scroll down to graphics parameters (im sorry if its not exactly called that, my Os is in French)
• and there i made an exception for both fallout3.exe and fallout3launcher.exe, to prioritize high performance (so the use of my GPU)
