Just flew the Mooney (my favorite airplane) from Friday Harbor to Arlington (KAWO) and made a beautiful landing enjoying the wonderful environment that FSX has to offer. I changed to spot plane view and looked back and found that a grey rectangular shape was beaming up from Seattle (See screenshot). I gets these briefly in FS9, so I am not surprised that they are appearing in FSX. My video card is new, so it must be a driver or motherboard issue. Either way, I am due for an upgrade.
One thing I did just before leaving Friday Harbor was reduce the tree texture size by 50%. This seems to have given me about an extra 1-2fps. You will notice on that screenshot that I was getting 8fps, with a max around 13fps. Earlier this evening, prior to the reduction, I flew from Santa Barbara (KSBA) to Cammarillo (KCMA) and got around 6-7fps and maxing out around 11fps. I can’t wait to reduce the rest of the textures, I think I can get an extra 5fps!
