antialiasing, anisotrophic filtering

I have 3 problems with openGL / windows drivers. First one conserns vertical retrace. When it is completely disabled in the control panel, there's no way I can detect it's off.

When it's set off unless application desides, it chooses to run at 90 fps. When it's set on unless application desides, it chooses to run at 60 fps. Always on sets it run at 60 fps.

60 fps is correct, as my screen doesn't support more.

this is on AMD 4830 card 10.12 version of drivers.

I have included 3 files to show how it's rendered

1) anisotrophic problem   anisotrophic filtering 16x

2) antialiasing problem antialiasing problem

3) without any antialiasing or anisotrophy set on control panel

                              without antialiasing and aniso

What do I do to get that kind of results?

One letter from that text consists of 64 polygon quads. Every vertical line shows different part of the letter -> one alphabet letter = 64 quad polygons.

 

Second problem is anisotrophic filtering. It completely screwes the image when it's set more than 0. The more set the more image corrupts. Is there a way to ignore the setting? At this case it should not be on because I'm doing 2d graphics not 3d. The following settings don't help.

The same thing applies to adaptive antialiasing. When it's set on it screwes the graphics.

On nvidia graphics cards there are no problems with those settings.
