On future games with the idTech 5 engine (Rage and Doom 4), Carmack says: "There are no firm plans for linux ports of the idTech 5 titles, but it certainly isn't off the table. I don't think it will be very difficult to get them running on the binary nvidia drivers, but bringing them up to functionality and acceptable performance on other OpenGL drivers would probably be a more significant undertaking than we could afford."
