Default Antialiasing settings via nvidia-settings no effect

Hello,

I am using KDE 3.5 and played a bit with the anti aliasing settings of nvidia-settings.

No matter what option I use, be it 2x biliniear or 4x bilinear or whatever it seems it has no effect, the fonts look the same. Access to /dev/nvidiactl and /dev/nvidia0 is there.

I know KDE itself has antialiasing settings and I changed them and these options do have an effect, but I like to use nvidia-settings to fine tune antialiasing.

Is there a bug or am I doing something wrong? How do I effectively change the way fonts look with nvidia-settings?

Thanx!

System: OpenSUSE 10.3
nVidia driver version 100.14.19
NV-Control version 1.13
KDE 3.5.7
X.org 7.2.0

These settings affect 3d games. They remove the 'jaggies' you see in those (corners of 3d objects).

Fonts are handled through Xrender and that's something of your desktop environment.

In KDE you can control font-antialiasing in the KDE-Control-Center "kcontrol".

Thanks for explaining.

Can't nVidia change this tool or the whole driver to also change Xrender font anti aliasing? I think it would be great if it was possible, so one could fine tune font anti aliasing beyond what KDE/Gnome allow.

Well 3d antialiasing and font-antialiasing are very different things - 3d antialiasing is performed by the nvidia drivere whereas font-antialiasing is done by the freetype library.

Font-Antialiasing is always done at highest quality possible (because its done only seldom), but 3D antialiasing is quite restricted because if its performance impact. So there is nothing to tune
