I'll have better mileage once I have 3d acceleration from the UHD 630 iGPU and Nvidia GTX 1050 GPU. Still on the scfb driver for video.
That said, as my PC is fast enough for me, I am able to play some of the less graphically dense games on it so far, like Armagetron.
Once I can get some 3D acceleration, preferably with the 1050, I am looking to run a third party Second Life viewer that has a native build. It's called Megapahit. Its main dev recommends I run a pure FreeBSD install, but I think I can get it to work with GhostBSD once the GPUs actually run for me.
