Does that mean if I purchase gsx level 2 my FPS will go down. Im getting a solid 25-30 FPS at most of the default airports. When I had gsx level 2 demo it went down to 12-17 .
Your fps was already very bad before, since I would expect to get at least 40-50 fps on default airports. You probably have too high settings and/or your system is not powerful enough to handle your settings, and adding the more detailed SODE jetways that comes with GSX L2 (which are now standard at KLAX) surely cannot improve fps on a system which was already struggling.
Try lowering the max texture size, it might help. Of course, the main problem is you are running FSX, which won't be able to use all your memory ( regardless how much you have ), since it's a 32 bit application, and the GSX L2 jetways work best in P3D4, since they have fairly advanced materials, which require a more powerful video card, which FSX won't be able to fully use anyway, since it's a DirectX9 application, with 12 years old shaders technology so, the more the scenery has advanced graphic, the better it will run on P3D4 and the worse it will run on FSX.
Another thing I forgot to mention is my gas trucks are now facing the wrong direction when fueling airplane.
That's not the "wrong" direction. Is the correct one, since we'll introduce soon a fuel hydrant, which will replace the fuel tanker in all parking spots with a jetway so, after the update, the tanker will be used only outside gates and will go back to the previous position.
Note that, the new Fuel Hydrant will require GSX L2, and will work on P3D 4.4+ only.
I have a back up cd from fs pilot shop and my serial number.
A "backup" CD for our products it's just a waste of plastic and a waste of money (it must be shipped), because our installers are always available for download with no limitations. We tried to explain this to retailers, and suggest stop selling totally useless backup CD with our products, but it seems a lost battle: they keep saying "user like them"...
Do not use the CD, only use the latest installer found on our site, both for KLAX and GSX L2.
