Oh thanks! I had seen that page before but didn't look closely. Looks like maybe if I disable visual effects in GNOME I might be able to make it usable, because some of the lowest end cards on that chart should be comparable to the Intel IGP on the Core i5. Or maybe I don't have proper drivers installed. But thanks a lot, this should point me in the right direction.

Hi Ibrahim,

If your system does not have sufficient graphics support, you can try and run gazebo headless. For reference, with proper GLX support, on a 2.8GHz i7 with nvidia 9800GT, default pr2 simulation launch script runs at roughly between 0.7~1.2X real-time.

Hi guys,
I'm just wondering, how much does the Gazebo simulation stuff,
specifically for the PR2, depend on the GPU? I've got a laptop with
hybrid/switchable graphics, i.e. Intel integrated + ATI discrete, and
right now ATI's Linux drivers don't support switchable graphics
properly, so I'm stuck with the Intel integrated, and I get about 5fps
in the gazebo simulation. Also, I frequently get crashes where it says
something about OGRE running out of memory. Is it supposed to be much
faster, or even basically real time? Thanks,
