for future dual gpu use reference (i think its called 'Optimus' technology):
in nvidia control panel you can add rule which graphics card to use for specified program
(strange in this case are the diffrent defaults - its fresh driver without any changes in settings)
This patch is useful if you want to delete a ragdoll.
I also can not reproduce the issue.
Glad it's working again!
If you find a solution and the problem is not related to bge, please report it here.
I can not reproduce the issue.
I'm not sure what settings etc. you have used but I have a feeling that the "bugs" are due to your own tampering with the .blend and the settings within the game engine.
Things you should consider doing:
- use Blenderartists.com game support forum if you have a problem like this! you are much more likely to get a fix for your game.
- append all the parts into a new .blend file Hope this helps
Looks good to me.
