What if my graphics card is too old to support OpenGL 4.3?

If your graphics card doesn't support OpenGL 4.3, you have a few options. First, you might consider upgrading to a newer graphics card. Second, you could try using an older version of Blender that has lower OpenGL requirements. Third, some users have reported success using older driver versions, but this is generally not recommended due to security vulnerabilities and potential instability.
