Some interesting native Linux games with OpenGL are mentioned in the menu below this point. But as there are thousands I will mention only very few. If the game supports Vulkan then see Vulkan.
Vulkan is perfectly supported on Linux and Android by all GPU vendors and it makes the need for OpenGL much less important, even though the GPU vendors provide big improvements all the time.
On Windows systems OpenGL is often slower than DirectX, it get much less attention and as of it’s limits Vulkan is a perfect replacement for both graphic API’s. Microsoft deprecated OpenGL as well (https://docs.microsoft.com/en-us/windows/desktop/apiindex/windows-api-list).
Apple announced that OpenGL is deprecated in MacOS 10.14 (https://www.phoronix.com/scan.php?page=news_item&px=Apple-Deprecates-OpenGL-OpenCL) and developers should use Metal, gladly the now open source project MoltenVK translates Vulkan to Metal, so there is no need to use this proprietary Apple API directly.
