Just tried the FS9 demo, unforunately, totally unaccepable framrate hit. Getting 4FPS max.!!!

As it was rather bad news to me, I have downloaded and tried the demo version, too.I have no idea what causes your problem but on my PC, which is rather old now*, it performs superb. With the default Cessna I got some stable 25-30 FPS (locked at 30) with AI, REX clouds and everything maxed.I would even say it is permorming better than other addon airports of a comparable size.The only thing I noticed was some stuttering, but that could be due to the demo version or even not related at all (as I've had some installing and messing lately). So, it looks to me like there is no definite problem on the Flightbeam side.BTW It looks stunning! A must buy, I'd say. * Intel Core 2 Duo E8400 3GHz, 4 GB RAM, GeForce 8800GTWindows XP 32 bit Home PL with the 3GB switch applied

Thanks for the feedback guys, will keep investigating tonight and report back if I can find what is causing the issues at my end - I'm sure it's a top quality scenery. Scott

Thanks Rafal for your input. Oh well, looks like I'm lost then. Too bad, the scenery looks so incredibly sweet. Thanks for anyone trying to help.

I too have had very stable frames (25-30) with this scenery. Tried the demo first and had no issues. This a very very well done offering for FS9. Hope you are able to get it sorted, so you can enjoy all this add-on has to offer.
