I just updated to driver 66.93 and now FS is all squirrelly, anyone know how to fix it? Thanks.
Roll back the old drivers.
Place some nuts outside your PC, and when the squirrel comes out, get him with a shovel.
I just installed the 66.93 drivers a couple of weeks ago, and haven't had any problems. Actually I installed them for the benefit of HalfLife 2, which is the main reason I haven't been posting here as much lately!
