| 51 | ### Raspberry Pi notes | ||
| 52 | |||
| 53 | You should use a version of SDL that is compiled to take advantage of the Broadcom VideoCore OpenGL ES hardware. This provides the best performance when running Lagrange in a console. | ||
| 54 | |||
| 55 | When running under X11, software rendering is the best choice and in that case the SDL from Raspbian etc. is sufficient. | ||
| 56 | |||
| 57 | The following build options are recommended on Raspberry Pi: | ||
| 58 | * `ENABLE_KERNING=NO`: faster text rendering without noticeable loss of quality | ||
| 59 | * `ENABLE_WINDOWPOS_FIX=YES`: workaround for window position restore issues (SDL bug) | ||
| 60 | * `ENABLE_X11_SWRENDER=YES`: use software rendering under X11 | ||
