I'm bumping this topic because I found a solution to this issue, it was related to the sound driver/device.
The arrows stutter or look laggy as if they were skipping frames (even when StepMania says it's running at 60 FPS).
In the file Preferences.ini
you need to change some settings related to the audio driver. The file is located in C:\Users\<your name>\AppData\Roaming\StepMania 5\Save
, and /home/<username>/.stepmania-5.0/Save
: This issue usually occurs in Windows Vista and greater. Change the entry "SoundDriver" as follows:
: Both "SoundDevice" and "SoundDrivers" need to be changed:
If the SoundDevice doesn't work, try changing the 0 to a different number, eg. 1, 2, etc.
This is because ALSA may assign the HDMI sound output to 0 (on some motherboards with HDMI like mine), which is probably not what you want.
The change to "SoundDrivers" is optional; you can leave it blank because StepMania will autodetect the driver by default.
These changes may not be noticeable if VSync is turned OFF. You need to turn VSync ON in both inside StepMania and your graphics card configuration.
I recommend running the "Calibrate audio sync" option again, because this also fixes the timing between the arrows and the songs (global offset should be set to 0).
Hope this helps other people having the same issue.
