I'm using the AMD R9 390X. And I can't change the FXAA settings through the RadeonPro or Radeon Software Crimson Edition. The P3D display settings is not suitable for me. I want further changes.
I've reinstall the system and P3D finding that is not my hardware wrong. It can change the settings for FSX but once turn to P3D. It fails again. I don't know what's wrong. Or amd is not support the P3D. The only way is buy a Nvdia Cards?
And sorry for my poor English.
