Libgdx no usa Opengl ES 2.0

Question

Preferiblemente, me gustaría usar OpenGL ES 2.0 para un nuevo juego en 3D que comencé a hacer. De todos modos, he estado desarrollando en una PC Ubuntu (no de primera línea pero decente) compré en 2010.

Gdx.graphics.isGL20Disponible() devuelve falso, y estoy bastante seguro de mi controladores soportan 3.3.0. Aquí es lo que estoy recibiendo de glxinfo:

Y mucho más que no tiene que ver con la cadena y/o extensiones de versión. Tengo todas las extensiones necesarias para Opengl ES 2.0 y mi controlador se actualiza a 3.3.0 (OpenGL 3.0-> 2.0 ES aproximadamente). ¿Es porque mi rasterizador de software es viejo? Si es así, probablemente haya otros en la misma situación (ni siquiera creo que haya tantas instalaciones de Windows que se hayan actualizado después de 1.1), y me gustaría apoyarlas también. ¿Cuál es la mejor solución posible?

Answer 1

Gdx.graphics.isGL20Disponible() no indica que su hardware sea compatible con GL ES 2.0. Te dice que el contexto gráfico gl20 se ha inicializado.

Debe solicitar libGDX para usar GL20 explícitamente. Ejemplo para Lwjgl Backend:

LwjglApplicationConfiguration config = new LwjglApplicationConfiguration(); 
config.title = "Game"; 
config.width = 800; 
config.height = 480; 
config.useGL20 = true; //this is important 
new LwjglApplication(new YourGame(), config);
