Yes, but Orbx textures even without PBR look better than default P3D textures with PBR. I am having an issue with TE Florida and trying to figure out if it's me or something else. Perhaps Orbx can comment on whether or not they'll update Global, Landclass, Trees, HD buildings to PBR ... big project and small user base these days.
Global and PMDG are working very well 50-60 FPS external and in VC with very high graphics settings and 44-51 FPS at very large 3rd party airports in PMDG. Be careful with Clouds at "Ultra", I run at "High". I also have OS GPU scheduling enabled, HT OFF as usual, but experiment with these might provide for a better (smoother) experience if one is having stutters:
[JobScheduler]
AffinityMask=255
P3DCoreAffinityMask=255
MainThreadScheduler=0
RenderThreadScheduler=7
FrameWorkerThreadScheduler=3
I can't find where these are listed in the .CHM but Jannie R. helped bring this to my attention ... they will appear in the Prepar3d.cfg after installation.
Cheers, Rob.
