Hello!
First, I'd like to say fantastic job on KIAH, by far, my favorite FSX:SE addon.
I have a couple of issues, not sure if they're related...so I come here for help.
1.) My taxiway/Runway textures look very blurry and also, where they meet the grass line. (Attached image)
2.) My Addonon Manager will not let me click "Force HD textures" (Attached image)
I have Intel HD graphics 4600.
Thank you.
