Chromium CEF GPU Context Contention & Desktop Window Manager (DWM) Hooking

Discord uses Electron/Chromium, creating continuous GPU rasterization draw calls. When hardware acceleration is misconfigured, it fights with your game for GPU scheduling priority.

The Discord in-game overlay injects a direct DirectX hook into game binaries, intercepting frame presentation cycles. Combined with Chromium hardware acceleration, this regularly causes 20-30% drops in 0.1% low frametimes. We configure Discord advanced settings, disable telemetry, optimize audio subsampling, and route background apps to low-priority CPU threads.
