Hi, thanks for you responce!
After sometime i also noticed that unreal engine also RAM and GPU Memory sensetive and may call “d3d device removed” when you dont have enough RAM or VRAM(mostly VRAM)
I got d3d device removed when tried to render scene that needs 45 GB~ Video Memory
i dont have much, before. i only got 32 GB Ram and 12 GB VRAM that.
So i only can get 28 GB VRAM (MaxRAM/2 + VRAM) . Also you cant just swap Shard Video Memory, it need only Physical RAM
After upgrading RAM to 128 GB, now i dont have any d3d device removed while working with really big scenes that can consume really big amounts of VRAM or RAM (excluding memory leaks, that can still crash your engine, but i did not got exactly d3d device removed)
How to determine that the problem is in RAM?
Try to monitor you Ram in TaskManager and if you get crash wher your current RAM = MaxRam then its yours’
How to determine that the problem is in RAM?
The same as RAM. I got crash only when VRAM and SharedMemoery was full.
If you crash not in this cases so the problem can be deeper in you hardware setup.
