Question Hi there! My game wont start up.

[Gergő Illés-Németh]

Hi, I just downloaded the game today (2026.04.01) and I get a white screen and than a crash. I saw that a lot of people have this problem yet no solution worked for me.

PC:
OS: Windows 10
CPU: AMD Ryzen 7 5800H
RAM: 32 GB DDR4 3200Mhz dual channel
GPU: AMD Radeon Graphics and RTX 3060 Laptop with 6 GB of VRAM (22 shared)
The game is installed on my C: drive.

This is what the event log said:

Faulting application name: KSA.exe, version: 2026.4.2.3942, time stamp: 0x68fa0000

I have tried a number of things:
Let all 3 exes through the firewall
Let all 3 exes through Exploit Protection
Reinstalled .net 9
Reinstalled .net 10
Run in admin mode
Updated to the latest NVIDIA GameReady driver (595.97)

So far nothing has worked, in the /logs/Archives I have Brutal.xx.log from the tries but all of them are empty.

The error in "... at Core.KSADeviceContextEx..ctor(Api inApiVersion)" (e.g. the game fails during vulkan render init) could mean that since you have a laptop with both an AMD integrated GPU and a dedicated RTX 3060, the game might be trying to launch on the AMD integrated graphics instead of the dedicated GPU.

I am not an developer but thats the explanation i came up with for the error log.

You could try to solve the bug by trying to force windows to use the NVIDIA GPU for KSA so that it does not use the integrated AMD GPU by accident.

I have not tried this out myself but it could work somehow roughly like this:

(maybe you only need to do one of both options or both options. I would try Option A first)

Option A: Windows Graphics Settings
- Open Settings -> System -> Display -> Graphics (or search "Graphics settings" in the Start menu)
- Click "Browse" and add KSA.exe from your installation folder
- Click on the entry, then "Options"
- Select "High performance" (wherever it does list your NVIDIA GPU) and save

Option B: NVIDIA Control Panel
- Open NVIDIA Control Panel
- Go to "Manage 3D settings" -> "Program Settings"
- Add KSA.exe
- Set "Preferred graphics processor" to "High-performance NVIDIA processor"
- Apply

Thanks for the suggestion, I tried it but it did not work. Also nothing changed in the event log except the time stamp.
