ShaderGlass fullscreen overlay for games

How fullscreen and borderless modes interact with shader overlays on Windows.

Start with borderless windowed mode

Borderless and windowed games are generally easier to work with than exclusive fullscreen applications. Open the game first, then position the shader overlay.

Keep the game responsive

Choose a reasonable shader, test input handling and reduce GPU load if you see stutter. If the game uses a protected renderer, overlay capture may not be possible.

Recording and streaming

ShaderGlass can be used with OBS Game Capture in supported setups. Verify what OBS captures before recording a long session.
