One other issue has come up. While using Windows and connecting to a big screen tv, putting game to fullscreen mode (1920x1080 @ 120Hz) will show the graphics not centered correctly (left hand icons with fuel amount etc are out of screen) and game is reaaally slow and laggy.
Alt+ tab to Windows and same back into game, and all is well.
After game is over, returning to main menu slows it back down again.
(can be corrected by starting game, and then Alt + Tab again twice, but have to do this at the beginning of every game)
This problem does not seem to exist in windowed mode, but with that the audio is not working.
Not a huge problem, but wondering what could cause it. Have tried 3 different Windows 10 laptops, same result on all, no system setting changes seem to do any difference.

Well it wasn't easy or too hard, but a somewhat complex to figure out what was going on.
Seems the Gamemaker platform doesnt trigger any events on resolution change of the display when on "true fullscreen". In fact it just keeps returning the old resolution through its apis until you resize the game, one way or another.
On fullscreen window, display resolution changes at least can be seen through game window size - so a display reset can be called.
So the game wont be true fullscreen - for the time being at least. Anyway only difference should be a minor performance hit. And TR is such a simple game - no one will notice 900fps max instead of 1200.
I have some testing still to do - so that html5 version wont break etc
When done I will release the update.
