My system is having performance issues when I run 3d clouds. If I use Pete Dowson's fsuipc file to limit visibility to 30 instead of the default 60 miles, will that make a difference as long as I have clouds set at 30 miles?ThanksRoger

this may not be an fspiuc issue. The 3d clouds area real frame eater. Try using the simple clouds setting. it still looks good, tho not so volumnous. Then, when you and I get get more powerful computers, we can go back to using the 3d clouds setting...:-)Sherm
