So yes it sucks but it should point out why > there is no reason why 3D should really be working on all cards. Thats true but a driver that does not work with 3D can hardly be called a working driver. Sure GPUs are more complex nowdays and we have limited manpower but most of this complexity (which people pay for) is for 3D. 3D shouldn't be considered as "nice to have" but an essential feature that should be working. But yeah talking is easy, actually fixing this problem is harder..... -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
