Yes, my target FPS is 60.
My workaround for now has been to have the indoor areas totally dark which is something I can do considering that the world is post-apocalyptic and there would be no electricity. When I remove the emissive lights the ghosting goes away.
The reason can be lumen screen traces, try typing
r.Lumen.ScreenProbeGather.ScreenTraces 0
in console. It will remove all screen space GI, but should remove ghosting too.
If you still need Screen Traces, you can increase Grid Resolution (default is 48). I didn’t test, but assume this will have performance impact.
r.Lumen.ScreenProbeGather.RadianceCache.GridResolution 256
I encoutered the same issue, no idea why either.
I’ve run into this and have come to a (decent) solution, it seems. Worked for me at least…
The bajillion-blades of grass using WPO shaped-meshes+wind-animation over long distances, w/lumen.
I have the following scalability-settings:
Using Lumen, no hardware-raytracing, DX11, regular (cascading) shadow-maps, SM5 I tested with DX12 and virtual shadow maps, SM6 and I get the same results as below.
I went from fast-motion (char-movement max-acceleration is set to 225 speed, speedish of my fastest mount I plan to make) and this visual. You can clearly see smearing behind the character. It comes and goes, more or less, but it’s always there:
to this:
by using the command r.TemporalAA.Quality 2. The default value (for me) was apparently 1. Even the grass looks a little better in the bottom-pic. Not so much the blur, the the color comes across with more fidelity (to my eyes).
r.Lumen.ScreenProbeGather.ScreenTraces 0
@socialdistortio - I have only one thing to say: THANK YOU.
I have been struggling with it for a long time and browsed half of the internet.
My problem is entirely gone after changing this config.
