This is being released as a 2nd beta called "Terrain Streaming Testing" to ensure I haven't broken anything from the Fixed Wing beta! This update adds the following.... 1. Terrain streaming system. This allows terrain tiles to be streamed in as needed which reduces overall RAM usage as well as allowing huge, if not massive map sizes. 500 km x 500km is easily possible with the only real limit being the time it takes me to create a tile. The terrain streamer only works on the Central Libya map and you should see the terrain tiles take a lot less time to load when starting a mission. Over all RAM usage has also been reduced from 8-12Gb to a more sensible 5.5Gb. This should make the game much more stable on devices like the Steam deck. My aim is to keep RAM usage below 8Gb. 2. New terrain textures. Seeing as RAM usage has been lowered I am able to cram in some extra splat map textures on to each tile. Instead of 3 they now have 6 giving much more variety to the desert. 3. New foliage. The whole foliage planting system has been recreated to give a much more realistic feel to the desert. You will now see hardy grassy tufts for the most part but in valleys and other depressions you will see more varied plant life. Terrain foliage no longer uses GPU instancing as the performance difference was negliagable. 4. New trees. You will now find trees living in the depressions and valleys where water is likely to gather. Trees are fully GPU instanced and have negligiable performance impact. Trees with leaves will react to your helicopter's rotor wash when you get close. 5. New U.I. I have started upgrading the user interface. Some buttons have been moved and their placement standardised across all screens. Most of the default menu screens have been upgraded to the new U.I. Mission planning screens still use the old style U.I. at the moment.
