Hi Everyone,Have been flying FSX in my new rig and it is beautiful...Took my first night flight ....KMIA to TNCM plenty of real weather clouds, full moon and the ocean was breathtaking at altitude..BUT...The clouds Had a grainy look with pink blotches almost like the pixels were not right.....the main sky above looked great but it was very layered starting at the horizon..around 3 distinct layers moving up ...not a smooth transition...Daytime flying is just beautiful....Any thoughts?........Monitor settings, video card settings?........As usual....thank you for any help....LarryIntel Core2Duo E6700 upgraded the fan to ZalmanCNPS9700nt2.67GHz@1066FSB 4MB CacheEVGA nforce 680i SLI 775nf-68AI Q2C SLI320GB Sata hard drivesst 850 power supplySamsung 20.1 LCD2x2gig corsair-6400C5DHXEVGA 8800 GTX 768MBXP OSAntec 900 case with extra fans

>The clouds Had a grainy look with pink blotches almost like>the pixels were not right.....the main sky above looked great>but it was very layered starting at the horizon..around 3>distinct layers moving up ...not a smooth transition...Sounds like it may be an AA and AF issue. (??) I have seen the same thing when I turned off AA and AF.RhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian
