Spent most of yesterday restarting/rebooting...lol Here is what I have tried individually and in various combinations with no change:
-p3d rebuild generated core files
-uninstall/reinstall GSX
-disable RTT
-del shaders and scene Indexes
-1024, 2048, 4096 in sim textures, which had no impact on timing or severity of blurries
-reset couatl on departure
-0% ai, 100% ai, various autogen draw distance/density settings
-affinity/no affinity in cfg
Sys resources stayed mostly consistent in all scenarios. GTX1080 45-65% load, 3-6Gb mem. cpu temps stayed in the 60-65c range, load never exceeded 90% on any core; devil's canyon. Process explorer working set 3-6Gb, virtual size 10Gb, system memory hovered at 50% physical usage.
