Image ghosting when increasing internal resolution

[FlyingElk]

Thanks so much for your time Maylmilae. I have recovered the sys folder as instructed and indeed the 'Ignore Format Changes' option is now there within the graphics menu. However, the issue persists whether this is checked or not... I've also tried changing the setting under the game properties config from true to false but still no dice.

Do you have any other suggestions please?
