Hi Damian,I would like to seek help from you. I have purchased AS2004 since last2 days. I found the FPS impacted and given a single FPS number once the thick clouds is there. I'm replace with chris Hi performace cloudsv2 & set the 3d clouds to 80% only. I only can get better FPS after Ichange the clouds layer to 1 layer only.Can you provide me some of the reference setting on AS2004. I like this program very much but just a little FPS concern.MY computer setting-Athlon XP 2200+-1 giga DDR ram-nvidia geforce FX 5200 128MB video card-winxp pro with sp1a-fs2004b/regards...alex ooi
