Natural markers are birds flying in the thermal while artificial markers show a coil following the thermal upwards If enabled either natural or artificial markers are used.

Thermal visualization will show markers for thermals.

Between 60 and 90 mi is a realistic setting for most conditions The highest setting is often beyond what a human eye can see in real life.

Cloud draw distance determines how far away clouds are displayed.

Special effects include moving waves, fireworks and other effects.

This setting takes a heavy toll on performance and is very buggy

Ground scenery shadows allows objects to cast shadows.

This setting will have the most impact on performance.

Autogen density determines how much autogen is loaded by FSX.

Extremely dense can be used on most systems

Scenery complexity determines how many non-autogen objects are loaded.

Land detail textures, leave this checked.

Low 2.X or higher is advised for best graphics. Higher settings impact performance but look better.

Water effects controls the wave action and reflection in water.

Set to 7 cm so that all terrain textures and photoreal overlays will display at their highest potential resolution.

Texture resolution determines the maximum resolution that terrain textures will be loaded.

Many addons require a certain resolution but there is no default FSX mesh of a higher resolution than 10m

Mesh resolution is the resolution of the terrain mesh itself.

A lower number will load lower resolution mesh at a distance

Mesh complexity impacts how far away mesh will retain a high resolution.

The higher this is set the less blurry distant terrain will be at the expense of increased memory usage and decreased performance

Level of detail radius impacts the sharpness of terrain around the user.

Aircraft self-shadowing is also bugged and decreases performance but adds depth and shading to aircraft.Aircraft shadows add depth to the sim but are somewhat bugged and decrease performance.High resolution 3-D virtual cockpit should be left enabled for best detail.Advanced animations allows many object animations to display, leave this checked.Light bloom adds a subtle bloom but decreases performance.Lens flare enables a camera-like flare when looking at the sun.Advantages are increased performance, enhanced lighting, and cockpit shadows Many addons and even default objects will not display properly and anti-aliasing does not work. This will allow FSX to load texture sheets up to 1024x1024 Global texture resolution should be set to Very High.Anti-Aliasing is dependent on whether you are using another utility such as Nvidia Inspector to force higher anti-aliasing.External limiters may yield higher performance but have been linked to blurries and stutters The frame rate can either be locked with the internal limiter or an external limiter.Set resolution to your monitors default resolution.
