ReShade review
A free, open-source overlay for deep visual customization across supported graphics APIs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ReShade is an open-source post-processing injector for games and video software. It adds an in-game overlay for configuring effects and presets, making it suited to players and creators who want to adjust a game's visual presentation. Available effects include SMAA, ambient occlusion, depth of field, color correction, film grain, and sharpening. Users can also create and share preset files through the in-game interface.
Its strongest advantage is breadth across graphics APIs and shader customization. ReShade supports Direct3D 9–12, OpenGL, and Vulkan, and includes the ReShade FX shader language and compiler. Depth-buffer access and detection support effects that depend on scene depth, while the add-on API allows extensions and game integrations. SteamVR overlay support broadens its use beyond standard desktop game rendering. The result is a tool with a wide visual-effects scope rather than a narrow collection of fixed filters.
ReShade also includes practical overlay utilities: FPS, frame-time, clock, resolution, and format statistics, plus screenshot capture and saving. Windows is the primary gaming environment, while Linux use is documented through Wine and DXVK, so platform fit is more qualified outside Windows. Choose ReShade if visual effects, shader control, preset sharing, or graphics-API coverage matter most. It is less suitable for users seeking a dedicated performance-monitoring tool or a simpler overlay centered on hardware telemetry rather than post-processing.
