"We have left this locked by default as about 10 of the over 100 enemies in the game have minor animation issues when the framerate is unlocked and we are unable to resolve this issue as it's a hangover from the original art assets. We wanted to add the ability to unlock the framerate to those who prefer it while not inconveniencing those who are happy with the regular fps for animation with these few quirky frames. After consulting with the beta testers we decided adding the line to the ini was the best solution all round"

"If your 2D assets such as text box art, minimap, etc, are messed up, this is usually a driver issue with AMD graphics cards. Please try updating your drivers to rectify the problem. Alternatively using previous issues of drivers has fixed this issue in the past."

"In some instances, Anti-Virus software may flag Mary Skelter: Nightmares as a threat which may prevent the game running or cause it to run at a lower frame rate and even to run out of memory. This has been experienced by a few users on Avast, AVG, BitDefender and Malware Bytes. To fix this whitelist the game / add it as an exception in your antivirus software.
- BitDefender users should also ensure that they make the game executable bypass Active Threat Defense. This has solved the memalloc (out of memory) issue for most users.**"
