I don´t know if this issue is related to a recent update but when I go to the video settings and change the AA level -> click OK, it will not be saved. It stays on the same setting. Everything else is saved. File check did not solve the issue.
Is your language set to english? If i use a language where the option entries are translated, it also don't gets saved. But when i use english it gets saved.
You are welcome. But you have posted it in the correct section, because that is a bug. The translation should not affect the functionality.
