Just in case, here is Sciter rendering HTML 3.2 specification document using Direct2D/DirectX backend on 3840x2160 screen: https://sciter.com/sciter-fps/ https://sciter.com/sciter-fps/ Real FPS is shown in window's caption (490 FPS). Sciter Engine (HTML/CSS/script) is fully contained in sciter.dll (4.9 Mb) (https://github.com/c-smile/sciter-sdk/tree/master/bin/32 https://github.com/c-smile/sciter-sdk/tree/master/bin/32) without external dependencies. It works on all Windows versions starting from Windows XP and provides choice of four backends to use: Direct2D (GPU and WARP), Skia (OpenGL and CPU) and GDI+ (just in case someone is still interested in mammoth's shit). On MacOS it uses Skia/OpenGL or CoreGraphics. On Linux it uses by default Cairo (good enough) and Skia/OpenGL as an option.
