Ok, I just found out a key factor that needs to be considered and which explains why some people are seeing ghosting and others not. I currently have HAGS off so I cannot try with frame generation, but even without here’s the thing:
Usually I have V-Sync on and set to 50% of monitor refresh rate. When I have this on, the ghosting is quite heavy. That is 30 fps in my case.
When I switch to 100% or even turn off, I get around 73 fps. In that case ghosting is almost vanished.
So the FPS are a crucial factor here. Unfortunately this makes it quite hard to use it in VR.
