'''A:''' As with any complex 3D model, this new version of the c172p is a bit more demanding on the computers than the older one. If you are having troubles with performance, try using non-HD liveries which use textures with lower resolutions, as well as other solutions that can improve performance (disabling certain graphical options in the Rendering Options, lowering the resolution of FlightGear, etc.). | '''A:''' As with any complex 3D model, this new version of the c172p is a bit more demanding on the computers than the older one.

Some tricks that help to increase fps is by disabling all GUI windows, including the menu bar and the orange fps counters at the bottom of the screen. You can display an alternative fps counter in the top left corner via the "Debug" menu and then selecting "Cycle On-Screen Statistics". Make sure to hide the menu bar by pressing F10 to see the counter. | |||
A second trick is to simply disable the rendering of all clouds if you don't mind. Start FlightGear with "--prop:/sim/rendering/draw-mask/clouds=0". | |||
If you notice heavy slowdowns when flying over certain scenery and you see FlightGear generating many "Warning:: Picked up error in TriangleIntersect" messages in the terminal or log file, you can disable this by starting FlightGear with "--prop:/sim/rendering/osg-notify-level=fatal". | |||
'''Q:''' Why are the windows getting foggy/frosty? | '''Q:''' Why are the windows getting foggy/frosty? | ||
'''A:''' If the | '''A:''' If the dew point of the cabin air temperature is higher than the surface temperature of the windshield, the windows will get either foggy or frosty. Use the Cabin Heat and Cabin Air levers (on the right of the flaps) to control it. The dew point rises with the temperature in the cabin, and it rises faster than the windshield temperature can adjust, resulting in temporary fog. If the air is very humid, the dew point is going to be very close to the cabin temperature, which makes it likely that it will be higher than the windshield temperature. Extra passengers will create a more humid atmosphere in the cabin. Try to increase air flow using the Cabin Air lever or overhead air vents in order to decrease the humidity or temperature. Alternatively, disable the effect by going to the menu "Cessna 172P", selecting "Aircraft Options" and disable the option "Enable frost and fog". | ||
'''Q:''' How do I increase the cabin air temperature? | |||
'''A:''' Increase the cabin air temperature by opening the Cabin Heat lever. In order to actually get a heated air flow, you need a medium or high EGT (Exhaust Gas Temperature -- the instrument between the yoke and the ADF instrument), and airspeed and/or sufficient propeller RPM. | |||
