One suggestion, copy and paste your fallout 3 folder to make a backup. That way if you dont like it, all you have to do is delete the fallout 3 folder and rename the copy. A lot easier than removing every file. I actually have 5 copies of my fallout 3 folder. This allows me to play different games with different mod layouts plus a "Fallout 3 - Pristine" which is a fresh install with all the tools. If I ever want to start a fesh game with fresh mods I just rename my current play folder then copy and paste this one and rename it to Fallout 3.
I agree with the above here as well. I dual boot and have a F03 directory in Win7 64 & WinXP32 plus the whole darn F03 folder backed up on a external drive. Too many playthrus have been ruined due to a reformat or bad tweak setting considering how much stress I can put on my system @ times.
I'm running

So far I'm finding that I'm getting great responce in WinXP and the visuals maxed out run solid. Win7 thou it seems sluggish and I can see odd issues with the grass @ times with low AA so I"m getting used to WinXP just for beth games again.
