This LD_PRELOAD library inserts black every other frame to reduce motion blur. Works with any OpenGL game uses glXSwapBuffers. The game may be darker and there may be flickering which could annoy some people. It is recommended that you increase backlight brightness , enable VSync and if possible use a 120+hz monitor to prevent flickering and dark images.
Compile using gcc -Wall -fPIC -shared -o blackframe.so main.c -lGL -ldl and run with LD_PRELOAD=blackframe.so **GAMEEXECUTABLE**. All games that use glXSwapBuffers are supported and EGL support is planned in the future. Since this game injects code into the game some anti-cheat software may get you banned.
