--- Comment #12 from Anonymous winehq72@mailcatch.com --- The same problem does not occur on windows, so it is not caused directly by a bug in these games but by an interaction with wine.
It is very common for people to just turn these settings on and forget them, since this is the only way to get improved graphics in old games and they usually have no/negligible impact on performance.
If it is confirmed that the anisotropic override is the cause, it would be interesting to check if the problem is caused by particular implementation in the driver/nvidia-settings, or if it is caused by anisotropic filtering itself. In the second case it could cause problems in newer games where anisotropic filtering cannot be turned off (and which are more likely to use deferred shading or similiar methods).
