How to reproduce:

Start Apex Legend
Start Blitz
After apex-internal.dll has injected, inject another small overlay dll (such as https://github.com/NightFyre/DX11-ImGui-Internal-Hook)
Apex get freeze in Present as long as the second injected dll called D3d11CreateDeviceAndSwapchain

nimble light How to reproduce: 1. Start Apex Legend 2. Start Blitz 3. After apex-internal.dll...

we can't help with that, it simply means that those apps are unable to work alongside our DLL being there, resulting in crashes.

but just to be sure i'm talking out of my ass, i'll be CCing @sullen meadow

since he knows the most about overlays and dll injection

I created a new swapchain and found the address of IDXGISwapChain::Present by using the virtual pointer of the swapchain, but create a new swapchain will result in the issue. How do you hook IDXGISwapChain::Present? BTW, it is ok to inject my dll before blitz does, Apex does not freeze after blitz inject
