I put the TI in and when I tried to play anything 3D the video freaked out. I dont know how else to describe what the video looked like other then it was blurry with bands of color running through the screen. I reinstalled the drivers etc but nothing seemed to work. I am using the Nvidia 23.11 drivers. I also tried the 28.32 with no difference. Device manager noticed the difference in the two cards, it listed them as Geforce 2 Ti and Pro. I put the GF 2 Pro card back in and all is well. Any Ideas? I am running XP Pro.
