Mesa 3D
Mesa is the open graphics stack containing OpenGL, Vulkan, OpenCL implementations and user-space drivers for many GPUs.
Why use it
Linux game development uses it to validate driver behavior, software rendering, and multi-vendor compatibility.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
Capabilities vary with hardware, kernel, and distribution versions; one development machine cannot represent players.
