Seems you are on the good path :) with the first patch i can play quake3 a little bit more (without it i get a lock within a minute or so). Ut2004 lockup too but at least now i can see the menu... If i apply the second patch it leads me to the past situation, a quick lockup... Jerome Glisse ------------------------------------------------------- This SF.Net email is sponsored by Yahoo.
