@ 3dfapman, I recently just bought the game yesterday from Steam along with the DLC story content: Baba Yaga - The Temple Of The Witch.
I can tell you that this game uses Direct X 11, and thus you would need either Windows 7 or Windows 10 to run the game.
Direct X 9 is a really outdated graphics driver that was used when Windows 98 and XP were around.
If I were a modder, and had some modding skills I would definitely make a mod for Rise Of The Tomb Raider for Lara Croft in her B-Day suit, and perhaps some new outfits for her too, but alas I lack the skills and the knowledge.
However, on the plus side, since there are some mods for the first Tomb Raider (2013) PC game, that even has a nude mod that someone made, it won't be long before someone creates a nude mod for Rise Of The Tomb Raider also.
A little time and patience is all it takes. I'm confident that we shall see some nude mods arise for ROTTR soon enough.
On a side note, WOW !! ... Look at those buns ! Did I just see a hint of camel toe too ?
