High FPS issues

[DCxDemo]

Steps to reproduce:

• disable vsync
• set fps limit to 300

Observed bugs, likely wasn't fixed for time delta at all or fixed imprecisely:

• Faster special bar shine wobble
• Faster main menu transitions
• Physics feel a bit floaty?
• balance is reported to be more difficult to handle
