If your graphics card has plenty of VRAM, you can set it as high as you want with no loss in frame rate, but as soon as the texture resolution requires more VRAM than the graphics card has, the simulators frame rate will plummet.

Instructions on setting the rendering options in X-Plane 11 are available here.

The following procedure will allow you to optimize X-Planes performance for your computer, regardless of the power of that computer or any limitations it may have.

Before we begin, we will need to be able to tell how fast X-Plane is running on your computer.

To do this, launch X-Plane and: Move your mouse to the top of the screen (causing the menu to appear) and click Settings, then Data Input Output.

Check the far right box next to frame rate item 0, in the upper left corner of the window).

This will cause X-Plane to display the current frame rate in the upper left of the screen during flight.

Close the Data Input Output window (either with one of the Xs in the corners of the window or with the Enter key on the keyboard).

You should now see how fast the simulation is running, in the freqsec output on the far left.

This is the current frame rate, given in frames per second (fps) Note that the frame rate will change depending on what is happening in the simulation.

Refer to the following to determine the significance of this number.

Higher frame rates indicate the computer isnt rendering with as much detail as it could.

Studies have shown that starting at about 50 frames per second, your subconscious mind forgets that you are looking at a simulator and begins thinking you are actually flying.

Increasing the Frame Rate Contents 1 Increasing the Frame Rate 1.1 Use the Rendering Presets 1.2 Changing Texture Quality 1.3 Disable HDR Rendering, Simplify Shadows, and Lower Water Reflections 1.4 Changing the Resolution 1.5 Optimizing Other Rendering Options 1.6 Tuning for Orthophoto Scenery 1.7 Modifying Cloud Rendering and Visibility 1.8 Changing the Number of Other Aircraft If the simulators frame rate isnt as high you would like, you can raise it by following the instructions below.

We recommend following these instructions in order, checking the frame rate after each major change until you find settings that give an acceptable frame rate.

Use the Rendering Presets Starting in X-Plane 10.40, you can quickly tune your X-Plane rendering settings based on five preset options: minimum, low, medium, high, and extreme.

Each preset was hand-built in an attempt to make good settings trade-offs.

If you dont want to spend a lot of time tweaking each individual setting in the Rendering Options screen, we recommend that you start with one of these presets.

In general, if your system is fairly old, try the low option and then switch to minimum or medium depending on your results.

If your system if very new, try the high and extreme settings.

Keep in mind that you will need to restart X-Plane to see the changes take effect.

Changing Texture Quality If your graphics card has too little VRAM for the textures X-Plane is loading (a very real possibility in Version 10), you may see a huge drop in frame rate.

Move the mouse to the top of the window, making the menu bar appear, and click Settings, then click Rendering Options.

The texture resolution drop-down menu determines how much video RAM (VRAM) the computer will use.
