| Flightgear requires a hardware accelerated 3D video card with OpenGL drivers to run at reasonable frame-rates. Using a video card without hardware acceleration might produce frame-rates around several seconds per frame. On the other hand, a 3-Ghz CPU with a GeForce video card should produce frame-rates near 60 fps in most situations. The frame-rate will vary with the complexity of the scene, which is constantly changing, depending on the number of models and surfaces within view at each moment.
| | For FlightGear to run smoothly, it requires a video card with OpenGL drivers. OpenGL 1.2 is required, and OpenGL 2.0 is preferred. Most modern PCs support OpenGL, but if you are having trouble with slow frame-rates, see [[Hardware Recommendations]] for more information. |

| Most modern PCs have hardware accelerated 3D cards. If you are having trouble running FlightGear, visit your card manufacturer's web site and download and install the latest drivers for your card. Appendix C of The FlightGear Manual has some further information on configuring your machine. See [[Hardware Recommendations]] for more detailed information. | |
