Radeon EQAA Anti-Aliasing Support Merged To Mesa 18.2

Typo:

by providing more coverage sampels per pixel.

Don't know. Long time ago windows nvidia driver was able to force a2c within certain games, far cry (the first) for example. Usually, I bet, game developer should implement this feature.

The article is not about Nvidia, your comment was totally far off and misleading.

Care to elaborate how?

Games already use alpha-to-coverage instead of alpha-test.

But you can't force older games to use it, unlike situation on Windows where the driver can (even sparse grid SSAA).

d3d9 games that support ATOC (alpha to coverage) can use the feature on gallium nine.
I look forward to add EQAA too (which is advertisable in d3d9 via MSAA quality levels).

Any progress on this?
I can do some testing (if my son or I have the 'right' games).

After second thoughts, I'm not quite sure this is worth it. Most game just won't enable you to pick EQAA. Thus the only way would be for a given MSAA level requested by the app to have the driver enforce the best EQAA respecting this setting (controlled by env var). However EQAA visual boost is very small, and thus the user would better just use max AA settings. Probably most cards can run max AA settings for d3d9 games.

Thanks for the update.
