Memory requirements

raylib requires some static memory allocated to store internal global data.

This table shows the specific requirements per module. Note that it does not consider the support libraries memory requirements, included libraries can require additional globals.

module	data type	x64 memory (bytes)	x86 memory (bytes)	notes
rcore	CoreData	3112	3096	cross-platform window, input, time, storage data; adds to PlatformData
rlgl	rlglData	2736	2700	OpenGL state, extensions and batching data
rlsw	sw_context_t	1896	1784	software rasterizer context data
rshapes	Texture2D, Rectangle	36	36	Texture and rec to map shapes, by default a white 3x3 pixel of the font atlas, to improve batching
rtextures	-	-	-	no static memory required
rtext	Font, int	52	44	Default font and text line spacing
rtext	char buffer[]	18432	17920	Static buffers required for immediate text management on multiple Text*() functions
rmodels	-	-	-	no static memory required
raudio	AudioData	4096	3408	Audio system, buffers and processors data; adds to miniaudio context data

rcore includes different modules depending on target platform, every platform module defines a PlatformData structure to contain the static memory requirements for that platform, size varyes by module.
