Xavier Del Campo Romero	8f230211bb	OsgCar.cpp: Do not create SDCarShader on "none" shaders ... Even if "none" shaders were selected, the game would still parse car.frag and execute the shaders, which is not the expected behaviour.	2025-01-07 00:28:47 +01:00
Xavier Del Campo Romero	c677c8d9e2	guiscreen.cpp: Reduce minimum required OpenGL version ... 3.3.0 was required only because one shader, namely car.frag, was arbitrarily requiring GLSL 3.3.0. However, it was already compatible with GLSL 1.1.0, [1] so the minimum required OpenGL version can be safely lowered to 2.1.

Xavier Del Campo Romero	21211a7aa5	guiscreen.cpp: Ensure successful SDL_GL_CreateContext ... SDL_GL_CreateContext can fail due to several reasons, such as GLXBadFBConfig on unsupported OpenGL versions.	2025-01-07 00:28:46 +01:00
