One with normal loading of a small map (only 661 Mb), and the second with loading of my current map 2,214 Mb)
Here on the second and crashes, I tried two attempts to download.
The computer is completely new, I decided to check. 9400F / 16 Gb RAM and 1660GTX / 6 Gb videoRAM. Drivers are the latest.
I understand very well that most likely 16 GB of RAM is not enough, this map works for me on another computer with a RAM capacity of 40 GB, but in the logs it’s kind of like a video error, right?)
upd^
Everything is much more wonderful and wonderful.
Added +8 GB of RAM upd2:
But that's not all)
rearranged operational memory from one computer to another., where it was 40 and so it worked. It turned out 4 slats 8 + 8 + 16 + 16 = 48 GB
I loaded the same map. In the task manager, it shows 38.6 GB of RAM loading, this is because the guns are silent and there are no freely roaming bitters

But I would not be me if I had not tried the same amount of memory as on a non-working configuration

I left 8 + 16 = 24 GB and loaded the same map, but in Windows 7. It loaded much longer, but it worked without problems, the FPS was very low at first, then it rose a bit to 41-43.
So draw conclusions about Win7 vs Win10.
And yes, in the minimum requirements for the game you need to write from 4 GB, and in the recommended ones - 64 GB

ps: If you are interested in saving, then I’ll upload without problems. I finally have an Internet optical 100 Mbps
