How to Clean Overwolf Gaming Overlay Cache & Temporary Files
Location & Quick Verdict
%LocalAppData%\Overwolf\BrowserCache\cache, shaders, and logs
Overwolf Gaming Overlay stores compiled Vulkan/DirectX 12 pipeline caches, overlay webcaches, temporary highlight buffers, and session crash dumps inside %LocalAppData%\Overwolf\BrowserCache.
How Compiled DirectX 12, Vulkan & Driver Pipelines Accumulate in Overwolf Gaming Overlay Cache & Temporary Files
Every time a modern DirectX 12, Vulkan, or OpenGL title launches, your graphics driver compiles hardware-specific Pipeline State Objects (PSOs) and compute shaders into binary cache buckets at %LocalAppData%\Overwolf\BrowserCache\cache, shaders, and logs. Across dozens of driver updates and game patches, shaders compiled for retired driver versions remain on disk alongside active pipelines—and corrupted shader buckets are a primary cause of micro-stutter and DXGI_ERROR_DEVICE_HUNG crashes.
When you clear Overwolf Gaming Overlay Cache & Temporary Files, the graphics driver automatically allocates a clean, defragmented shader cache directory on next launch and compiles only the active pipeline states required by your current driver version. Note that any files locked by the Desktop Window Manager (dwm.exe) or active tray overlays are safely skipped.

Frequently Asked Questions
Is it safe to delete Overwolf Gaming Overlay Cache & Temporary Files?
Yes, 100% safe. Cleaning Overwolf Gaming Overlay's cache and old log files reclaims 1.8 GB – 12.0 GB of disk space and fixes post-update UI stutter while keeping your game saves, clips, and controller bindings safe.
How much storage space will cleaning Overwolf Gaming Overlay Cache & Temporary Files free up?
Users typically reclaim 1.5 GB – 9.5 GB on Windows 10 and Windows 11 systems depending on update frequency and active cache retention in %LocalAppData%\Overwolf\BrowserCache\cache, shaders, and logs.
Will deleting Overwolf Gaming Overlay Cache & Temporary Files cause shader compilation stutter in games?
Only briefly on the very first launch of a game while your GPU compiles fresh shaders for your current driver version. In fact, clearing bloated or corrupted shader caches often resolves persistent frame-time spikes and driver crashes after GPU driver updates.
Where is Overwolf Gaming Overlay Cache & Temporary Files located on Windows 10 and Windows 11?
It is stored at %LocalAppData%\Overwolf\BrowserCache\cache, shaders, and logs. You can paste that path directly into the Windows Run dialog (Win + R) or File Explorer address bar to inspect it.
