Oh god. I've got the same problem as you boys. I own a x800XT radeon card and I hadn't played LFS for some days until today and I saw my fps fall to 15-20. I'm thinking that maybe it is due to the HT and Dual Core support that the new set of drivers have...
That made some of my games run clearly faster, but I got dissapointed with LFS's poor performance.
I hope 5.13 comes out soon and solves it.
Do you , those that have an x8xx series card, have a Dual Core or Hyper Threading processor?
Is this my first post? Yes, I think...
