One thing that I don't think has been mentioned.
The i810 drivers are notorious for working well with some games and terribly with others.
This is no fault of Ubuntu/Linux, but the responsibility falls on Intel for not developing the drivers very well
then abandoning them officially leaving it up to the Linux community to try and make them equal to their
***dows counterpart. I hope this may help in some way even if it's not what you wanted to hear.
