Gazebo dead slow on 8x2.7GHz cpu with a NVidia GT650m gpu
To simulate our robots super fast, hopefully near real time, I ordered a laptop with an 8-core Intel i7-3830QM CPU and a NVidia GT 650m GPU, but with a Intel HD4000 gpu on the motherboard too. I heard NVidia is reasonably well supported under linux nowadays, so NVidia instead of ATi.
I installed a fresh Ubuntu 10.04 Lucid, and not all was well: Long story short, Gazebo runs dead slow this laptop, at 0.01x realtime and 7-8 fps. Also, the Z-buffer is messed up, showing some further surfaces in front of nearer surfaces. Any clues on how to fix this, maybe where to get newer drivers for this card under linux etc?
RViz segfaults directly, but that's something for a different question, I guess.
EDIT: I did try the latest (the day before yesterday) NVidia drivers for this GPU but that lets gnome run in low graphics mode.
EDIT2:
Running lshw
gives this:
- pci:0 desc: PCI bridge *- display UNCLAIMED desc: VGA controller vendor: nVidia
- display, desc: VGA controller vendor: Intel version: 09
network bottleneck?
Its not the network, as Gazebo only runs locally and not with ros nodes over a network in this setup for now.
