I guess I have been wondering about the RAM strategy of the game engine like many others here.
Personally I think the usage is way too low … or way too “pessimistic”. Unless there is a lot of memory pressure in the operating system (the extreme would be paging activity) I would love the game to use more … in order to cache more data.
I do a lot of sightseeing … and so I often switch between the cockpit cam, the external view cam … and the drone cam. Now the drone often lags behind the aircraft and so the (LOD) data for that view point is typically (very) different.
This results in a cam switch triggering a very noticable “re-buildup” of the 3D assets (textures, objects etc.)
… and that process is often reeeeaaaallllly slow. The pop in of items can in the worst case take up to almost a minute.
From the outside it is hard to understand what takes so long here. PCI transfer speed towards the GPU can not be the limiting factor (we talk many seconds here … for a few GB at best) … if the “SSD - SATA - RAM - CPU postprocess - RAM - PCI transfer to GPU RAM” steps are the cause then I really would prefer the system to utilize way more GPU RAM as well as CPU RAM in order to cache as much of the “historic” (already pre-computed) data as possible.
The new slider from WU6 goes into that direction … but it clearly is not as “aggressive” as it could be.
Right now I see (at most) a 25% RAM utilization … and I would love more RAM usage (when RAM is present).
