The Texture Max Load Editor is a free application developed from the ground up for Flight Simulator X.
The Texture Max Load Editor will change the maximum texture resolution that Flight Simulator X can load. Many flight simmers have environment add-ons, such as Real Environment Xtreme, that make use of High Definition and Super High Definition textures. These textures can go up to a resolution of 4096 pixels square. However, the default maximum resolution for Flight Simulator X is 1024.
