Mouse control issues

There have been many issues reported by players with mouse lag or unresponsive controls. Symptoms include:

• The mouse moves in steps, as if it's on a grid.
• Combos are hard to pull off as keys are only responsive some of the time. It is almost impossible to dash.
• Mouse movements cause the camera to tilt upward and spin wildly.

There are multiple possible causes for these issues. Try one tip at a time until something works.

List of tips

• To fix high-speed spinning/tilting mouse movements, turn off HiDPI scaling:
  • Windows 8: Right-click Oni.exe and choose "Properties". Go to the "Compatibility" tab. Check the "Disable display scaling on high DPI settings" box.
  • Windows 10: Right-click on Oni.exe and choose "Properties". Go to the "Compatibility" tab. Click on the "Change high DPI settings" button. Check the "Override high DPI scaling behavior" box. Scaling should be performed by "Application".
• Install the Daodan DLL, which has a "performance patch" that could fix timing errors caused by faulty chipsets. This fix has been reported to work by some people. (If you have the Anniversary Edition installed, you already have the Daodan DLL.)
• See this patch on PCGamingWiki that adjusts for monitors which use refresh rates above 60Hz. (Note that you can download the pre-patched app from that page rather than applying the hex edit yourself.)
• Force V-sync in the Catalyst/Nvidia Control Panel.
• Cap the frame rate at 60fps with your graphics card control panel.
• Place Oni on a second screen that runs at 60Hz, by moving the Oni window while running in windowed mode or by turning off your primary display.
• Run in windowed mode (use the "-noswitch" argument or double-click run_wind.bat). If you were already using windowed mode, try running in full-screen mode.
• Update your graphics drivers. Do not use Windows Update; instead go to your graphics card's website and download the drivers directly from there.
• Higher graphics settings can make the problem less noticeable by lowering the frame rate closer to or below 60. Try forcing 8x antialiasing in your graphics card control panel.
