The problem with 3D support is essentially that you need to use the proprietary Windows drivers with direct access to the GPU (because GPUs themselves aren't virtualizable). There is a way round it using VFIO and video passthrough (I use it for gaming) but it requires a lot of setup and depends on your specific hardware, BIOS and chipset. poc _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
