direct x 10 is disabled in my fsx.cfg. you should always run it in dx9 and you get no shimmering with sparse grid supersampling. the fsx.cfg i posted was there for the values to be set, not to copy and paste. so no wonder your plane was black cause dx10 is off in my settings. hope you can get it running. if you want send me your fsx.cfg and i try to tweak it for you. i need your hardware specs then.
