How to read this report

RENDERER is the name reported by the browser. It may identify ANGLE, a software renderer, or a privacy-masked value; it does not guarantee identification of the physical GPU. WebGL 1 and WebGL 2 are checked separately.

Values such as MAX_TEXTURE_SIZE are advertised context limits, not measurements of VRAM or free memory. This tool does not measure temperature, power, driver version or game performance. Keep device, browser and settings consistent when comparing reports.
