- LaserGRBL - use new OpenGL preview with hardware acceleration, best option!
- LaserGRBL (soft opengl) - use new OpenGL preview with software rendering
- LaserGRBL (disable opengl) - use old rendering without zoom and progress color (same as v6.x)
If the most advanced version "LaserGRBL" does not work for you, or have bad performance, you can try to switch to "soft opengl" or to "disable opengl" mode.
