The extension allows for a simplified API where pPresentationInfo is NULL and the second call to vkAntiLagUpdateAMD() is omitted which makes it necessary to separate frames on vkQueuePresentKHR(). The second main difference is that the wait time is now based on the previous input stage plus the average frame time. This greatly smooths frame pacing. v2: - measure the GPU frame time directly - Only try to evaluate frames which are likely to complete within the waiting time - Calculate the average absolute deviation of the total frame time and use that to determine the slack time v3: - move frame separation to vkQueuePresentKHR() - tightened frame pacing aiming for at most 1ms overlap Acked-by: Tatsuyuki Ishi <ishitatsuyuki@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/41727> |

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
