It is, but it requires a lot of modding and patience nowadays. It's mostly in the communities hands to "fix" games so they work flawlessly in 3D, but that sometimes takes a long time, sometimes even 6+ months after release date. Many games also don't get a fix if there is not enough interest (popular games always get fixed). Some games are 3D ready "out of the box" but that's rare these days.
