This means, you could set the sim to "Minimal" texture resolution. If that number exceeds the available VRAM your system has, you can lower the "texture resolution" settings, in order to fit it all into your system's VRAM.Ĭarenado's latest v10 planes have a special protection on CERTAIN textures, protecting those from resolution degradation as the "Rendering Options" are lowered.

This can be done in X-Plane's "Settings>Rendering Options" window, and is outlined in a PDF document included with Carenado's aircraft.Īt the bottom of the "Rendering Options" window, there's a text line that indicates how much video memory is required to run the sim at the current settings. The most effective way to fit large amounts of textures (which is the case with the HD-series of Carenado planes) into the available VRAM is, to use texture compression and to reduce the texture resolution. Since the sim only runs as fast as the slowest link in the chain, it is crucial to NEVER exceed the amount of your system's VRAM in X-Plane's rendering settings. When the textures and 3D objects loaded into the sim (Yes, this includes scenery as well) exceeds the limit imposed by the amount of the video card's VRAM, the overflow gets diverted to the computer's physical RAM, which is many times slower than VRAM. Carenado also states a recommended VRAM requirement of 1 GB for its latest planes, but it's important to become familiar with how these system requirements are to be understood. What is important to understand about this, is how VRAM affects performance in the sim, especially when flying complex HD aircraft.Įvery video card has its own memory, denoted as "VRAM." Laminar Research recommends 1 GB of VRAM to run X-Plane 10 smoothly, but it may be that with the addition of a HD Carenado plane, the total memory usage climbs to beyond that available GB of VRAM.

has published MINIMUM system requirements, as well as RECOMMENDED system requirements for the simulator itself here. However, numerous hi-res textures and detailed 3D meshes, as well as increasingly complex plugins do require a powerful computer to run them.
What can be done to fix this?Īs time goes on, Carenado is using increasingly more hi-res textures, in order to satisfy the ever-increasing demand for detail.
