Hi Irin, thanks for reaching out. I'm sorry to hear you're having issues playing the game. 4GB of RAM should be plenty.
Are there some other RPG Maker MV games where you don't have the stuttering issue? If yes, then it might be related to a particular plugin used by the games that are giving you trouble, or it might have something to do with the version of RPG Maker MV that was used to create the game (Death? Preposterous! was made on an older release of RMMV, version 1.5.2 just FYI.)
If you're having the same issue with all other RPG Maker MV games you try to play though, it might be something related to the engine itself, or your particular system perhaps.
In any case, I'm not certain I'll be able to help solve this sort of issue for you, and you may be better served contacting RPG Maker's support team to get their assistance directly.
However, a few ideas off the top of my head that you might try if you haven't already:
- Playing the game in Windowed mode instead of Full screen (or vice versa.) You can toggle between modes in the game's options menu, or by pressing the F4 key while the game is running.
- Updating your graphics drivers to the newest version supported by your system, or if you're already using the newest drivers, maybe trying a slightly older version to see if the issue is present (sometimes new versions can cause new issues too.)
- Try running the game in compatibility mode (I really don't think this should be necessary normally for MV games, but it's worth a try if all else has failed.)
That's about the extent of what I can think of to suggest that might help. I hope that you're able to find an answer that works for you. If I can help in another way, feel free to reach out again!
