I did a scan of London this morning, flying low in a grid pattern with 30 GB rolling cache. Which is not enough. This search pattern at 500 ft downloaded 30.26 GiB in total
Confirmed use of rolling cache as network activity stopped completely every time I crossed my path then go up again to 80 mbps treading new ground.
Enough data to get an accurate guess, it’s between 41 and 44 GiB of data in total.
I had to do this at half sim rate reducing my speed to avg 60 knots with network activity spiking to 113mbps already (on my 100 mbps connection)
That’s with terrain detail at 200
Double the LOD increases data load by about 1.6x and double the rate of travel obviously doubles the bandwidth needed.
There is a problem where allocated memory keeps increasing, the sim basically falls behind updating the rolling cache and the game crashes on my system when it tries to allocate more than 40GB (16 GB physical ram) hence the CTD. I have to pause and wait for allocated memory to go down, it was about to crash again when the rolling cache was full. (Normal load is about 25 GB allocated)
Anyway I got a good look at how detailed the data is while paused
Hanging wires are visible
All the towers for overhead wires
Open structures
Open bridges
Cars
House boats, power converters, light masts
Construction sites
Just so much detail
Beware here I hit the building, boundary boxes are wide
It will be a tough task to optimize this
