FSX/P3D. Orbx has really prides itself over the years on their FTX regional packages. But as of late, it's the rest of the world that is gradually becoming the ultimate Orbx FTX region. Now with Global, Vector, and openLC, comes Trees HD. FTX Trees HD is a complete overhaul of your sim's autogen tree textures, lending new and incredible immersion to your flight simulation experience! Years in the making, developer Scott Armstrong has used his keen eye for natural-looking vegetation to result in a depth of realism that simply must be seen to be believed. The new textures are double the resolution of default trees, resulting in unbelievable detail, and are derived from high-resolution photos of real trees for maximum realism. They have been expertly edited and color-matched to give you the top-quality flight sim experience that you have come to expect from ORBX. The most incredible part is that Trees HD will actually IMPROVE your sim's performance! New optimized tree models reduce the burden on your system, resulting in up to a 20% INCREASE in FPS and no increase in VAS usage compared to what you are experiencing now.
