Moonsword said:This is assuming they're using FS2_Open (which they should be) so yes, HT&L is in it normally. In all the versions of the SCP builds (Source Code Project, the group working on the released source code to FS2 to enhance it, enabling things like autopilot) I've run across recently, HT&L is the default option.
You do NOT have to run in HTL mode in the current builds. It helps a lot if you can, as FS2_Open seems less stable in non-HTL mode in my experience and is considerably slower.
I have the misforune to be forced not to use HTL because my system's video chipset can't handle HTL.
without HTL you need a VERY fast cpu and even then... I am not sure if you will be able to run the game. It IS esseintial to run it in HTL mode, all GPUs nowadays do support this feature.
