The Flight1 ATR performs well in FSX ! But you cannot simply install it in FSX. There are some steps to undertake, you can find a description of how to do this on the F1 ATR forum. I am running the ATR on FSX SE without problems, well, only the propellorblades disappear behind clouds, But that is e well known issue with FS9 models flying with FSX I use the ATR for my flights in the Canary Islands, great fun !!
