Here you can see the video of 3D Wayfinder application running on 4K lcd monitor. Tested project is really large (around 2000 POIs, 250k polys, 8k transparent polys, 60 materials), but we still have around 25-30 FPS, which is not bad. Of course the PC has 2 GTX-970 GPU-s in SLI.

Currently we are changing the Wayfinder data loading, to make the initial loading faster.
