I'm playing with i-tec docking station with DL-6950 and trying various games to see what's the difference vs direct GPU connection (on a desktop). So far what I noticed:
* World of Warcraft doesn't really change performance
* Frostpunk, Skyrim seems to loose some FPS
* Fallout 4: big FPS drop
* Witcher 3: black screen menu, can't really run the game
* 3DMark benchmarks: won't run
* Unigine Superposition benchmark: runs with a bit lower score
So are there some limitations of what DisplayLink chips can and can't handle well?
WoW runs as windowed DX12 while other are DX11 fullscreen.
(and also I get only 30 FPS for 3440x1440 display -
