You have a TNT2. It's probable that this card doesn't officially do 1600x1200 @ 85Hz when in 32bpp. The "nv" driver ignores the specs and will try to do it anyhow, though. When the "nv" driver does that do you get static when moving windows around and such? NVIDIA's drivers print out: (--) NVIDIA(0): Display device CRT-0: maximum pixel clock at 8 bpp: 250 MHz (--) NVIDIA(0): Display device CRT-0: maximum pixel clock at 16 bpp: 250 MHz (--) NVIDIA(0): Display device CRT-0: maximum pixel clock at 32 bpp: 215 MHz which probably prohibits running that mode, which probably needs a pixel clock of 230 or so. It probably works in depth 16 though. Mark.
