In 2022.2, we added Use OpenGL Texture Compression to the Render Options > Visualization Advanced > Advanced Rendering preferences to compress textures in OpenGL to save VRAM and possibly improve performance due to lower bandwidth requirements.
Textures with dynamic content, such as web engine textures, image sequences, and images created by vrVirtualEye and vrMoviePlayer2, are not compressed, so the texture update is not slowed down.
