| Summary | 0001901: Add MSAA 6x option | ||||
| Description | Older graphic hardware (Radeon R300g) supports up to MSAA 6x and having the possibility to select MSAA 6x under preferences would be great. Side note: adding information to preferences GUI FreeCAD restart is needed when changing Anti-Aliasing mode probably wouldn’t hurt. | ||||
| Additional Information | On Linux it is possible to force MSAA 6x mode for mentioned hardware like this: export GALLIUM_MSAA=6 freecad | ||||

Adding MSAA6x should be not a big issue, however, it may be a good idea to check which option is available in the hardware and only present those. I would need to investigate this. The restart thing is only in current development version, 0.14 stable changes the AntiAliasing without restart. I have a few ideas how to change that, but that needs investigating. I will takle both issues when my UI work is done, that may take a while |

ickby I hope you don't mind if I assign it to you then. |

no, actually I wanted to do this too, somehow forgot that :) |

If some (standard) way of checking hardware/driver available MSAA modes exist it for sure would be great for FreeCAD to only show available modes. For example as mentioned hardware does not support MSAA 8x setting this option produces the same result as if mode none was selected. No "radeon: Acquired access to AA optimizations." is printed to stdout. User could get confused thinking MSAA does not work at all or thinking it might be FreeCAD bug. In reality hardware does not support MSAA 8x but MSAA modes up to 6x works just fine. If there is no (standard) way of checking hardware/driver available MSAA modes exist i am guessing having 2x, 4x, (6x) and 8x will still work for majority of FreeCAD users just fine and don't spend to much time on this. Changing Anti-Aliasing mode without restarting FreeCAD again that would be great and that should be priority when you decide to work on this again. Cheers. |
