See the Intel Mac build's page for Mac-specific issues.
Most of the problems in Oni itself can be solved by using the Daodan DLL or by updating your drivers, but see below for more details.
The installer on the CD-ROM, OniSetup.exe, may no longer run in Windows 10. You can extract the game data from the installer's data file (ONISETUP.002) using Universal Extractor.
Have you gotten this message?:
There are several reasons why Oni might exit with such a message. The most common cause was solved with the introduction of the Daodan DLL, but if that doesn't fix it, this page contains a thorough list of things that cause Oni to "blam".
See Mouse control issues.
There are several degrees of severity (from crappy textures to ugly textures to OMFG). That's always a driver issue. Try and get a recent driver for your GFX card (upgrade to Catalyst if you have an ATI, etc.). But sometimes, Oni is incompatible with modern stuff. Try and get a really old driver, then :)
Low frame rate
- Power management
This can be a problem on notebooks. Under certain conditions, the performance of the computer will decrease dramatically, for example:
- if you run on battery power
- if you let the computer overheat
- Driver issue
First let's make sure that your graphic card has Direct3D and AGP acceleration enabled. Click on Start, Run, type "dxdiag", and press OK. You will see now various information about your DirectX and your computer hardware/software. Click on display, and check the Direct3D/AGP acceleration checkbox. If it is off, try enabling it, and if it is cannot be enabled, your graphics card may have not have this option, or Windows is using your card as PCI instead of AGP. In this case, try updating or re-installing all your motherboard drivers.
Now, if acceleration is enabled like in the picture above, try installing or updating your graphics drivers; don't use the ones that come with Windows. If you have an Nvidia card and if it is old (like GeForce 2 or Riva), I recommend you install an older driver. My recommendation is one from the 28.x and 60.x. range; these seemed to work better with my old card.
