This reduces the fixed function hardware bottleneck in vertex shading heavy sections with d3d9 DXVK. DXVK always declares 6 clip distances, and with https://github.com/doitsujin/dxvk/pull/4508 it writes 0 for disabled clip planes. But while working on this, I also discovered that other games also write constant clip/cull distances: Foz-DB Navi21: Totals from 442 (0.56% of 79206) affected shaders: MaxWaves: 10880 -> 10900 (+0.18%) Instrs: 283569 -> 282493 (-0.38%); split: -0.38%, +0.01% CodeSize: 1497596 -> 1491948 (-0.38%); split: -0.38%, +0.00% VGPRs: 18928 -> 18888 (-0.21%) Outputs: 3026 -> 2970 (-1.85%) Latency: 1051990 -> 1048878 (-0.30%); split: -0.47%, +0.18% InvThroughput: 184190 -> 183366 (-0.45%); split: -0.45%, +0.01% VClause: 6071 -> 6077 (+0.10%); split: -0.38%, +0.48% SClause: 6724 -> 6725 (+0.01%); split: -0.12%, +0.13% Copies: 19624 -> 19160 (-2.36%); split: -2.44%, +0.08% PreSGPRs: 18634 -> 18526 (-0.58%) PreVGPRs: 15522 -> 15465 (-0.37%) VALU: 156964 -> 156330 (-0.40%); split: -0.41%, +0.01% SALU: 41802 -> 41748 (-0.13%); split: -0.13%, +0.00% Reviewed-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32518> |

`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.
