Problem

You can experience issues with hangs or crashes that are caused by high VRAM.

Affected MAK ONE Products

VR-Engage

Solution

If that is the case, use the ‑‑limitEntityTextures or ‑‑limitTerrainTextures command-line options to use only mipmap levels at or below the resolution for entities or terrain. Use two integers for the width and height. For example:

vrEngage.exe ‑‑limitEntityTextures "1024 1024" ‑‑limitTerrainTextures "1024 1024"

If you continue to experience crashes, use ‑‑limitGpuMemoryPercentage in addition to these command-line options. Typical values are between 85 and 100, for example: ‑‑limitGpuMemoryPercentage 85. VR-Engage does not make new textures or buffers as a percentage of the available video RAM beyond the specified percentage. This applies only to VR-Engage-side textures: terrain insets, entities, indirected osgEarth layers (feature_geom and buildings). It does not apply to SilverLining, Triton, or osgEarth tiles. The latter are controlled by the .earth file options.
