SharpDX DeviceLost Exception on FullyExternalCS2 — DirectX12 Environment

[ErenGamerLP]

Hi @sweeperxz,

First of all, thanks for releasing the FullyExternalCS2 project — amazing work.

I'm currently running it on a system with DirectX 12, and I'm getting this unhandled exception when the overlay tries to initialize:

SharpDX.SharpDXException: HRESULT: [0x88760868], Module: [SharpDX.Direct3D9], ApiCode: [D3DERR_DEVICELOST/DeviceLost], Message: Unknown
at SharpDX.Direct3D9.Direct3D.CreateDevice(...)
...
at CS2Cheat.Graphics.Graphics.InitializeDevice() in ...Graphics.cs:line 67

It crashes right after trying to create the D3D9 device. I noticed the overlay uses SharpDX.Direct3D9, but my system runs with DX12, and I'm wondering if this might be causing the issue.
Should I downgrade my DX version or change something in the code to make this more compatible?

Let me know if there’s a fix or workaround — or if you’ve encountered this before.

Thanks in advance!

try installing DirectX versions 9 and 10 and make sure the game is running in windowed mode.

Hi, does FullyExternalCS2 have an in-game menu or overlay UI for settings? If yes, how do I open or toggle it?

There are only settings in the txt file, there is no menu yet.
