After having problems with the Nvida driver installation I could not get fullscreen antialiasing (FSAA) to work with the new drivers. After doing quite a few tweaks and checking and re-checking my installation and configuration I e-mailed Nvidia and got the following responce: **************************************************************************** There was a change in the FSAA with the 1251 drivers that didnt get updated with the documentation. The __GL_FSAA_QUALITY variable is no longer correct. It is now __GL_FSAA_MODE. Setting it to 3 will enable 1.5x1.5, and setting it to 4 with enable 2x2. Any other value for your card will not provide FSAA. **************************************************************************** This is an undocumented change in the drivers and may interest those who have upgraded and then lost some functionality. My system specs are below for those interested: AMD 1.333GHz 266 A7M266 Geforce2 GTS 64MB Mandrake Linux 7.2 Kernel 2.2.17-21mdk XFree86 Version 4.0.3 FSAA is great feature of these drivers and makes onscreen 3D modeling look incredible.
