Wayne S has recently presented an awesome realistic version of the League of Legends map.
The scene is running on an AMD FX 8350 and GTX 1060 at around 60-70FPS (Epic settings). He had to optimize the whole thing to get it running on his rig.
"There is a lot of extra detailing that can be distracting. I wanted to make the scene work both top-down and first-person, so having the detailing on both mattered but for an actual game, you'd need to cut those out," noted the artist.
