Thanks for the reply, John!
I am running ORBX and your suggestion seemed to help with the land textures but I'm still having issues with clouds, mainly, and some weird artifacts popping up.
I was able to isolate it to when I run a new virtual cockpit on one of my other monitors; immediately the clouds take on weird crystal shapes and I get the veils and curtains. As soon as I close the window, the clouds on my main cockpit (middle screen) all slowly start going back to normal.
I did a flight around KTMB my home base and the textures and clouds run smooth and perfect on just one display. Add in another display and it goes haywire. My GPU and CPU does not run above 70% often at all, even in 3 display mode so I'm thinking I have settings to tweak in FSX.cfg or the NVIDIA Inspector program; just not savvy enough to know where to tweak lol!
