<font color="red">'''Note:''' FlightGear 2.10 users seeing crashes during simulator startup (without seeing the actual aircraft/scenery) with very old graphics cards that lack GLSL (shader) support should know that there used to be a bug in 2.10 that broke support for graphics cards without any shader support. In other words, if you are able to run other OpenGL software, but cannot even display the about dialog in FG 2.10 using the minimal startup profile detailed below, it is almost certainly your graphics card's lack of shader support causing the issue, because FlightGear 2.10 tries to copy graphics card information to the property tree for debugging purposes, to allow end-users to provide better troubleshooting reports - ironically, this very feature introduced crashes for all 2.10 users without any GLSL support. This issue has been fixed in FlightGear 2.11+ </font> | <font color="red">'''Note:''' FlightGear 2.10 users seeing crashes during simulator startup (without seeing the actual aircraft/scenery) with very old graphics cards that lack GLSL (shader) support should know that there used to be a bug in 2.10 that broke support for graphics cards without any shader support.

If FlightGear crashes (or looks/performs very badly), it's possible that this is due a number of reasons, such as limited hardware resources (CPU, GPU, RAM etc) or insufficient driver support - so crashes are not necessarily due to a faulty program. Also see [[FlightGear Benchmark]]. | If FlightGear crashes (or looks/performs very badly/slowly), it's possible that this is due a number of reasons, such as limited hardware resources (CPU, GPU, RAM etc) or insufficient driver support - so crashes are not necessarily due to a faulty program.
