You need to add this to your .qsf file for timing-driven fitting:

set_global_assignment -name ROUTER_TIMING_OPTIMIZATION_LEVEL NORMAL

Also, if you want synthesis to be timing-driven, add this also:

set_global_assignment -name SYNTH_TIMING_DRIVEN_SYNTHESIS ON

There are check boxes for both of these settings in the Settings dialog box.
