I don't know; is my graphics card going south. Maybe not enough ? Any suggestons would be appreciated. Only the Carenado 337 is doing this.

Looks like a classic case of the SP2 patch for FSX is not installed on your system. (I could be wrong though!)CheersDave

Hi Thedcn!Do you use EZDOK Cam addon? Then you could try to run the EZDOK config tool.I also have seen some strange behaviors in FSX when using the automated webpage FSX configurator by ******* Altuve. Maybe delete the FSX.cfg file and let FSX build up new from scratch with a new start of it ?!

Thanks guys. I have gong through most everything. I'm going to uninatall and rsinstall from scratch. Will post the results.

How much memory does your GPU have? As Andy1975 mentioned, before unistalling anything suggest to delete the fsx.cfg and check if the problem is still there...

This might be one of those cases where having the "HIGHMEMFIX=1" switch in the GRAPHICS section of your fsx.cfg would come in handy. I've had that parts-missing problem before, and this fixed it.

Good idea, the highmemfix is the only 'tweak' in my whole FSX setup!

I uninstalled and re-installed the plane. Everything works fine now. After reading your post spotlope and seeing bstolle comment I added the highmemfix to the fsx confi file. Firing off FSX now to take a look. I have had some occasional lag with the gauges filling out.
