HiIs it possible to improve performance with PMDG B737.It is not so bad but in correlation with for example PMDG B747 I'm not satisfied.The biggest problem is, when I open radio panel and try to change COM freq, simulation stopped (stuttering) as I rotate buttonPC Conf:Intel C2 E6750 2.8GHz4 GB DDR2ATI HD2900PRO 1GB DDR4ThanksEdin

This is not normal behavior, look for something else besides the 737NG. I used to fly it on a P4 with much less horsepower, the only problem I had with COMM was FS9 has a bug that would cause a rare CTD when touching the COMM Freq.. never have figured that out and quit using COMM (easy for me since I don't use an ATC service). Anyway, back to your problem. Are you using any other addon such as squakbox?

Hi.I'm using Active Sky and when I'm online IVAP.But I didn't see such a behaviour with other aircrafts.Also I'm rotating freq with middle mouse wheel, and only on COM panel it has slow response.Same if I use left mouse button.I don't have this ,let say lag if I for example rotating NAV freq.Same behaviour with or without IVAP.Something wrong here, I will try to reinstall.Anyway thanks.P.S. Performance of B737 is lower then B747 (which is great a/c maybe the best for fs9)Edin

HiAbout performance issue, no progress.Same problem when i press left mouse button , simulation paussed. If I hold left mouse, simulation is stopped until I release the buttonBut only with COM panel.I will try to reinstallE.
