I decided to give something to the community, not sure how useful this will be but...
Fallout 3 was resently released and there are loads of people who have problems with it so I thought I would share some solutions that worked for me:
1)Changed gameresolution to 1280x960 and windowed and no antialiasing (rest of settings I use high/very high settings), (this also fixes the 'zoomed in issue' when pipboy is open)
2)Changed my desktop refreshrate from 75 to 60hz (since I have a TFT its no big deal really to have it at 60)
3)Changed the iShadowMapResolution=256 line in the fallout.ini (fallout3.ini?) to iShadowMapResolution=1024
And the second thing that could work would be:
I found a fix made by Skullptura for making this, it it mainly designed for his own released Fallout 3 rip but there are several people it worked for that used other rips and releases so I thought I could share it to u guys

These solutions are not thought up by me but by (First One) Fallout_Andy and (Second One) Skullptura and Gurgh for hosting the file
I just wanted to give something to the community and finally get out of this leech status, not sure how the rep thing works but, please +Rep
