KSA crashes on start

[Gismo65]

Game Version​

ksa_v2026.11.10.5801

Operating System​

Windows 10 Pro 64 GB, Radeon RX Vega 56 8GB

What Happened​

After executing KSA.EXE the whole monitor flashes with a black background back and forth.
Alt-Tab-Del and pressing "Task-Manager" suddendly brings up the KSA "configuration" window.
When I check a box or try to change the settings, the flashes reappear.
Same procedure to bring back the KSA "configuration" window with Alt-Tab-Del.
When I press "Start KSA" a black screen is shown and a blue loading circle. After a minute ksa closes completely.

What Was Expected​

Well, I expected, that I can lower Textures, Shadows, Casters and so on to a minimum, but nothings working.

Reproduction Steps​

1. Every step, same error.

Reproduction Rate​

always

ErrorOutOfDeviceMemory

your GPU has run out of VRAM. Try running tghe game with lower settings

Thank you for answering.
I already lowered to 4k settings, but this morning I tested with the lowest settings possible.
The monitor still flashes, and I can bring up the game window only with pressing Contr-Alt-Del and clicking on Task-Manager
After I click "Start KSA" the flashes reappear. Pressing Ctrl-Alt-Del - Task Manager to bring back the game window I see the game loading.
For a split second I see a glimpse of a picture but then KSA closes.

So I tried again. I disabled Texture Streaming and Shadows in the configuration window and started the game again.
But after the text "planet renderer ... Planet Transparencies" the game closes instantly.

I'm noticing a handful of mentions of 3840x2160 in there, are you trying to run the game at 4K window resolution?
I think even at min settings a Vega card is so old that may be part of the problem. 8GB should be enough to run that in a 1080p window though.
