Nvidia: Inferior Open GL filtering quality
 

According to current investigations from PCGH, Nvidia's drivers don't always render what you expect them to do. We compared older and brand-new drivers with a Geforce 7 and 8, using Windows XP x86, Vista x86 and x64.

The Control Panel allows the user to disable all the "optimizations” concerning the anisotropic filter - but now it's obvious that these options only affect Direct 3D and not Open GL. Disabling the "optimizations” and setting "High Quality” still results in shimmering textures in our tested games (American McGee's Alice and Prey). The Riva Tuner shows why: the OGL filtering restrictions are still active.

You will find more information in the article which is in English, btw. We have animated Gifs and detailed pics to show the differences in picture quality.
