I have since found this little dickens. While trying to fix my fsx ai stuff this thing must have gotten deleted. This dll came up while trying to load a traffic editor so I found it and placed it where it was supposed to live. It makes a lot of difference as it turns out.... fewer shakes, clearer scenery and so forth. I do not know if win 7 or 8 was sent with it but evidently fs9 and fsx needs it to display smoothly. Might be worth a look before you throw a brick through your monitor.
