This update focuses solely on memory management within the game.
Memory usage in Central Libya is now much better. It could top out at around 10-12Gb depending on how much you flew around. It should now be around 6.5Gb and pretty stable.
If you do noticed memory usage climbing then pressing "esc" to bring up the menu will also force the game to re-evaluate what assets it is currently doing and delete any unused assets from memory.
This main effects system RAM rather than GPU VRAM. VRAM is handled pretty much independently by the GPU drivers and so I don't really have any control over it.
