Hi everyone,I'm a long time user of Activesky 6.5 with FS2004. I thought I had everything configured as well as possible, but lately I've been bothered by slow frame rates/stuttering at certain airports or when I have a lot of (IMC) weather. My system is pretty good...dual core 2.8 Ghz, 2 gigs ram, an ATI Radeon 3600 HD video card with 1 gig ram etc.Anyway, I made some changes that I thought would improve frame rates, (like changing target frame rate to 22, and backing off some of the terrain detail). but now, when my Activesky injects weather, and I go to an airport that should be fogged in, I have pretty much IMC conditions when airborne, but clear visibility on the ground.Any advice on how to get back my zero visibility when the metar calls for it? Are their optimal settings you'd like to recommend?Thanks.
