Hello Geoslake, I am sorry to hear that you are having this kind of problems on your system, but it looks like this behavior is caused by compatibility between the graphics and the game.
These games you are playing are older than your HD graphics; so this is an expected behavior. I recommend you contacting the game developer in order to find out if this is a compatibility problem or something else.
Something important that I would like to share with you is that in order to have Vsync always enable, it will be necessary to select "driver settings" in the Intel HD graphics control Panel.
Thanks Sylvia, of course the developers (sierra) don't support this game anymore
Although the fact that there's no problem on nvidia (and ati btw) leads me to think that Intel drivers are culprit here, not a game which has been working flawlessly for more than 10 years...
I'll at least try to find a driver archive, maybe an older version will do.
