A fix for hopefully most dual CPU users that get Lag

Hey everyone. Me and my friend were both gettign the same problem, a wierd lag that would cripple the game for a couple seconds at a time and then jutter around like that repeatedly till our patience wore out.

Just today, after delving deep within the Main Fallout 3 tech forums, I found a fix that actually worked for both of us.

If you havea dual CPU, run the game. once in the main menu, alt tab out. then ctrl-alt-del to bring up the task manager and under processes, right click fallout 3 and hit set affinity. turn off the second CPU. now load up the game, and voila, no more criplling lag. You still might get mild jutters every once in a while, esp when loading tonnes of textures, but they wont be crippling jutters, thats for sure.

If someone is out there to Sticky this, please do.

Fallout may the cores, the ini may need to be tweaked to do so, but it's possible, check the Tweak Gruides site.

 

What you report is something like you don't have the multicore AMD or Intel fix for the XP (in the Intel case the fix is from MS itself, AMD have it's own).

Fallout can use the cores, the ini may need to be tweaked to do so, but it's possible, check the Tweak Gruides site.
