Anyone know why the very thin stratus layers kill FPS? I can run nice puffy cumulus's (two layers) and get more than double my FPS if I were to run a some stratus clouds...Anyone know why??? in the pics you see the first shot with about 8fps, the second shot is around 18http://forums.avsim.net/user_files/179049.jpghttp://forums.avsim.net/user_files/179050.jpg

I have not noticed any difference in FPS between stratus and cumulus. ?? But I will pay more attention in the future...Maybe something with your 6-series card?For my system, it's the number of layers (irregardless of cloud type) that can bog it down.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
