I found out about this just today! Like five seconds ago!
You know the tile jitter issue that was plaguing my game on some people's computers... apparently Game Maker has the very same issue:
I find the best way to maintain a nice retro look in a scrolling game in Game Maker is to set the View Sizes like Hideous suggested earlier.
What you do is set the view to something like 319 x 239 and then set the view port 799 x 599, if I remember correctly. The reason for the one pixel off is to fix a bug that exists in GM6 amd 7 that occurs with certain NVidia cards that leaves a blank pixel between tiles when the port is scaled. Strange stuff. Let me know if that works out for ya.
That's the same bug! But obviously it doesn't occur in every game-making program, because it would be a more commonly known issue.
So Ashley, what are your thoughts on this? Is this a reparable issue in Construct? Or is it just something that's always going to be there because of certain hardware?
