: Turn off manual GPU overclocks. Drop your core clock by -50MHz using tuning software to test if hardware instability is causing the driver timeout. Phase 5: Re-Install the DirectX Runtime Web Installer
External programs can interfere with the game's rendering process.
GTA V stores temporary shader files that can become corrupted. Deleting them forces a fresh recompile.

Move any arithmetic that does not change per pixel or vertex out of the shader and into your CPU-side application code.
The keyword typically refers to a specific graphics subsystem error where the Direct3D (D3D) shader pipeline fails or encounters an unexpected state within the graphics driver. This issue is most commonly reported by players of Grand Theft Auto V (GTA V) and other demanding titles like Monster Hunter: Wilds or Palworld .
