Hello @Jon Clarke. Appreciate you taking a look at the scenery_packs.ini order, thanks!
By optimizing I assume you mean there were no problems (that would result in bad rendering/loading) but it could be structured better?
That could be useful feedback for the xOrganizer dev(s).
I will try it out though and run some tests.
Rig:
I'm running on a 6700K 4.4GHz, SSD, 48GB RAM, GTX1080.
Settings:
Have been running Vulkan for a while, seems I have higher FPS on OpenGL though, to my surprise.
Visual Effects: High (HDR)
Tex Quality: High
Antialiasing: 2x SSA+FXAA
Anisotropic Filtering: 8X
World objects: Medium
Reflection Detail: Minimal
Draw shadows on scenery: Off.
I generally average 40 on complex airports and 50-100 in the skies.
EGPH has me down to 5-8 fps however facing east on stand 3, so that's not quite workable. If I look North or West however it goes back to 50 so that's would suggest something in the scenery there.
Had a similar issue at EGNT, but I've found a workaround and posted about it here: https://forum.orbxdirect.com/topic/202539-xplane11-egnt-poor-performance-and-runway-contours/
Before I know for sure what's going on I just have to run more tests with vulkan/openGL and having certain scenery enabled/disabled. For now I don't want to hijack @Locarno1's topic and you can just regard this as a "weird, I had the same thing happen". If I'm able to pinpoint it, I'll report back.
Maybe it's time to just reinstall x-plane after couple years of tinkering with it as well :p
