## Running on emulators
|
||||
You must have the 'trails' options turned off from the graphics settings, or a white overlay may appear over the 3d render
|
||||
|
||||
## Fine tuning settings
|
||||
Two experimental modes, 24 bpp (640x480x24) and Anti Aliasing are provided in the Graphics settings.
|
||||
|
||||
- When using HDMI or VGA out, it is recommended to turn enable 24 bpp mode. Note that you also have to disable the 'trails' effect.
|
||||
- Anti Aliasing will work with or without trails, however trails enabled will have a bigger performance hit in that mode.
|
||||
|
||||
Enabling any of those modes may result in some missing geometry under heavy scenes (more likely with AA mode).
|
||||
They can also be combined.
|
||||
|
||||
## How to report issues
|
||||
- Take a photo of your tv/monitor and vmu
|
||||
- open a ticket via https://gitlab.com/skmp/dca3-game/-/issues/new
|
||||
- state which elf you have used (eg, https://gitlab.com/skmp/dca3-game/-/jobs/8725216645)
|
||||
- write something descriptive of what is/went wrong
