I am loading 2 models into gazebo-2 and find that the ratio of real-time is never better than 0.5 and is typically 0.2. currently using => Geforce GTX 750Ti 2-slot PCI-e 4GB. My processor is an Intel-i7 with 8GB of RAM. What type of graphics card is required to run at full speed?
Now that I updated the Nvida driver to the latest version, I see a ratio of only 0.17 for the tutorial with the PR2 model and the gas station. http://gazebosim.org/tutorials?tut=ros_roslaunch I am guessing that there must be a check-box somewhere to tell gazebo to use the stream processors on this card.
You can increase the simulation speed by changing the physics values in your world.sdf: http://sdformat.org/spec?ver=1.6&elem...
For example, I use:
<physics type="ode"> <max_step_size>0.004</max_step_size> <real_time_factor>1.2</real_time_factor> <real_time_update_rate>300</real_time_update_rate> </physics>
This way you can simulate a larger time step per iteration and thus increase the real time factor.

what model are you using? those seems like pretty good specs to me
