goldberg_emulator/overlay_experimental/windows/DX12_Hook.cpp
Nemirtingas 547cbdbb4e Added barrier to DX12 overlay.
Gears5 seems to have a problem with the overlay. While loading and in the main menu, it works fine, but if you press enter, it crashes saying the GPU is not responding. Can't debug it with CODEX, it checks for a debugger.
Works fine on sniper elite5.
