Once I connect to the server, similar to what I had with Vatsim, I get a visual reduction in quality and a FPS reduction to about half of what it normally is, which is 55+. Another issue was my PTT wasn't working, but I think I know what the problem is. I'll provide a before and after screenshot, any thoughts would be nice.

Note: My computer hardware should be more than enough to run FSX, I have a GTX 670 OC, and an I7 3700K @3.5.

After connecting

I don't know if you can tell, but after connecting it's very clear that there are jagged edges everywhere, and mipmaps are gone. I've also added high res attachments for further inspection. Thanks!
