It's old hardware at this point, but it still runs anything I throw at it.
So yes. It can handle 3D Games.
Honestly, 32 bit OS is on it's way out since more and more games are requiring more than 4GB of RAM access. Even when you get into modding older games like Fallout: New Vegas, for example, you'll begin to run into errors and crashes due to the RAM limitations of 32-bit systems.
Our team currently has ideas for a 3D Hentai game in the future, but the cost for what we want to do is too high right now.
