The most common reason for this is the game is running over its required 59.95hz, the game is hardcoded to run at 59.95hz and this cannot be changed. To solve this, check [Game resolution and locking FPS](setup.md#game-resolution-and-locking-fps) of the guide again.

!!! tip ""
Make sure that your unpacked data looks like this:
- JAx (Game binary revision folder where 'x' can be A, B, C, D, E, F, G)
- data
- sidcode.txt
Any other files are optional and don't have to be removed as these are not required to run the game.
Refer to [Using iidxhook-12.conf & RtEffect.dll](setup.md#using-iidxhook-12conf-rteffectdll) again and check if you have followed all the instructions explained in it.
