POSSIBLE SOLUTIONI've just done a flight from
EHAM (FlyTampa) to EGCC (UK2000) and had no blurries. What I've done is the following:
1. Delete all files in
c:\ProgramData\Lockheed Martin\Prepar3D v4\SceneryIndexes_x64\ and let P3D write new ones
2. Delete shaders in
\AppData\Local\Lockheed Martin\Prepar3D v4\Shaders\ and let P3D write new ones
My rig:
i7 7700 @4.2 with 32GB DDR4 and GTX1080Ti on Win10x64 and a 4K monitor
P3D4.3 with EZDOK, ASP4, ProATC, AivlaSoft EFBv2 and almost everything from ORBX
Reshade and TomatoShade+Reflections
The following tweaks are in prepar3d.cfg
[DISPLAY]TEXTURE_BANDWIDTH_MULT=120
TextureMaxLoad=6
[SCENERY]MaxRegionsPurgePerFrame=1
[MAIN]FIBER_FRAME_TIME_FRACTION=0.11
[TERRAIN]TEXTURE_SIZE_EXP=9
Forget the tweaks, and just try the first two suggestions and post your findings.
Maybe it helps for someone. Will fly again tomorrow and see what temperamental PeeThreeDee is coming up with because you never know.
Good luck
