According to threads on various RB-Boards graphics corruptions still seem to be one of the remaining major issues. I still get them regularly, when aircraft or balloons are flamed. I would like to quote the following explanation from the Promised Land Website ( http://www.wingwalkers.org/jasta1/newplmain.htm ):
Graphics corruptions - Known issue with graphics in RB2 that sometimes corrupt during gameplay, this is due to the larger more detailed graphics that put a heavier load on your video card, and the routine that RB2 was written to communicate to your video card. In essence, RB2 was made to communicate texture management to Voodoo I, an older Voodoo II cards and will at times get "confused" and display wrong or corrupted graphics with newer Voodoo II cards or better.
None at this time, a few work arounds to the problem are as follows;
Change your settings properties for your 3D video card to limit texture memory to 2 megs (this may have an effect on some peoples framerates, for most though, this is the preferred work around).
Change your ingame screen resolution to another setting, and then back to your original setting.
Alt-Tab and task out of rb2, then Alt-tab and task back into the game.
For those that experience DTD's when trying to alt-tab in and out of rb3d;
Change your ingame screen resolution to a different resolution than that of your desktop.
Unfortunately the Alt-Tab function does not work on my sys when using the wrapper.
