Bevy 0.16 has a GPU driven rendering path now, enabled by default on platforms where it's supported! It uses bindless resources and multi-draw indirect to hugely reduce drawcalls. GPU 2-phase occlusion culling is supported. CPU overhead is minimized by aggressively retaining objects on GPU. - ThreadSky

Your contributions are nothing but incredible! Thank you for your hard work on bevy

Thank you for your hard work! Looking forward to seeing how it’ll improve our perf.

As an example of the performance, Activision's Caldera map, with ~30k meshes and millions of polys is about:
* 60 ms/frame in 0.14;
* 45 ms/frame in 0.15;
* 9.1 ms/frame in 0.16 (with all my PRs landed).

By way of comparison, Blender won't even load the glTF file, it's so big.

Thank you! I really appreciate all of your hard work!

This is amazing. How does this compare to major “industry” engines? Is there a fair comparison for it? (I couldn’t find anything by searching)

I believe GPU driven is fairly common in AAA engines. Unreal uses it in Nanite, but not for the "normal" path yet. Most other engines are CPU driven I think.

incredible work!

Thanks for all your hard work, I'm always blown away when I check up on progress and see all the important work you are doing. Legend.

It's been really lovely to see your plans pay off here! Your work, and all of the rendering reviewers and testers have done an incredible job.

I'm glad I could play a small role in this and keep the merge train rolling along.

a long time ago I remember having a chat with you at a bar and I came away thinking "he just can't stop wanting to implement everything on the GPU, what a tragic compulsion!" and now years later I am just so happy you have found the perfect fit <3
