Ok i got the nvidia omega 66.93 drivers, and set all the stuff yall said, including texture size to 256 by skuzzy's word. I saw a marked improvment in the driver update, but minimal if not losses with the optest. i saw gain in optest for ground views but lost a little on the full vis. here are the 2 results.
