Oh yeah. Trying to get Black Mesa - which is a HL2 mod that became a game in its own right - to look right on a modern Linux PC has been less than fun. Textures, lighting and shadows are messed up in many places, basically breaking the flashlight most of the time. The game is 99% there, but that other 1% is impossible to ignore. The game plays fine… when you can see.

Kind of glad I got the game on sale.

But anyway, yes I’m kind of surprised that the textures seem to be different in the two screenshots. The lighting is necessarily different because HDR isn’t well supported (if it is at all) on Linux, but I would have thought that keeping the textures in line would be something Valve would be able to do.
