So I've been having sporadic video problems for the last two months or so, and recently they've started happening all the time. I run XFree86 with the NVidia drivers on an old TNT card (Diamond Viper 550, I think), and recently I've been getting absolutely atrocious performance from things that previously had run fine (transparent Eterms in particular). It's like the lag of a slow remote connection, even when typing in a local window. The only thing I've found to make it go away is switching back to the stock nv driver (and losing Xv acceleration). I'm really at a loss to explain this. It started happening with really nothing relevent changed.
