Problems
There have been many issues reported by players with mouse and sometimes keyboard control:
- The mouse moves in steps, as if it's on a grid.
- Mouse movements do not move the camera consistently; the speed varies widely.
- 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.
Potential solutions
Is the camera spinning around?
- 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".
Do you have a high refresh rate monitor?
- 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. The recommended software for doing this is RivaTuner Statistics Server.
- 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.
Do you have a high DPI or high refresh rate mouse?
- You could try adjusting your mouse's DPI, but odds are that the problem is really coming from the poll rate. If it's set to 1000Hz, change it to a lower number like 125Hz. The poll rate may be adjustable on the underside of the mouse itself or may be a setting in the mouse's control panel.
Other things to try
- 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.)
- 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.
