I got the game to run on my below spec computer... just wish I could fix the outdoor jerkyness and lag. I have a AMD Turion 64 TL-60 dual core with 4 gb ram and an ATI RAdeon 1200 graphics card in my laptop. Don't have any problems running Oblivion at all, but wish I could fix this minor issue with playing FO3. Does anyone here know any tweaks that I can do to the .ini file that would help? The game runs perfect in the vault and indoors, just gets slow to respond outside.
