Good day,I have long been gone from the sim world due to my RL flying career development, but now I decided to go back.I have used most of the tips from this forum to setup my FS9 sim as well as my hardware.The sim runs relatively smooth except random drop of performance in 2D panel view.I have 35-40fps on average with smooth sim, then all of a sudden it drops to 6-7 fps.When I change the view to VC or Spot view then sim 'restets' its fps back to the good level.I would appreciate your expert review of my settings and pointing out where I might have gone wrong.Here's my hardware setup:HP

you very much,Dom

Hello Dom,It is difficult to tell where the culprit is. I don't consider myself an expert, but will nevertheless try to help you with some suggestions. With regard to the graphics card settings: Nhancer is outdated and as far as I know not even compatible with todays Nvidia drivers. What you need is Nvidia inspector (does normally come with the driver). Or did you call it nhancer by mistake? Anyway, search the forum for recommended settings of the inspector.A few recommendations for the FS9 cfg file:- Try limiting FPS to, say, 25- Texture Bandwidth Mult may be increased to 400- Terrain extended levels: change 232 into 4- Try to reduce the cloud coverage density to 6 or 7- Switch AntiAlias off in the simRegards,RenéEdit: Your graphics driver is rather old, so it might work with Nhancer. I would however suggest to upgrade the driver and switch to Inspector.
