docs(twitter): add 2075769880092037309 corpus (NOTimothyLottes Vulkan queue-choice rethink)

4-post thread, highest-engagement NOTimothyLottes thread in the corpus (42 likes, 5063 views, 2 reposts). Don't search for the ideal {presentation,graphics,compute} queue - just use queue 0. AMD: render via compute on queue 0, present on queue 1, decouple for front-buffer racing. NVIDIA: queue 1 is DMA, queue 2 is compute; queue 0 = gfx + present, dispatch on queue 2 by default. Tangent: someone complaining about the bitmap font in Post 1 looking like a captcha.

+Rethinking Vulkan queue choice. Traditional double-buffered games might do something like the code below. Find the queue that does {presentation,graphics,compute}. First off this seems like a lot of unnecessary work when one could just choose queue 0 and be done with it ...

+AMD on Linux (RADV) and Windows. Queue 0 just works. But note both platforms support doing present on queue 1. So on AMD I'm likely going to render via compute on queue 0 [to reduce chance of preemption] and present on queue 1. And have both decoupled (for front buffer rendering)

+NVIDIA is more complex. They put a DMA engine in queue 1 slot, and compute engine in queue 2 slot. Some sometimes queue 2 slot can or cannot do present (varies by driver). So maybe present on 0 (gfx queue), and dispatch on queue 2 by default for NV.

+@NOTimothyLottes Am I having a stroke? What is this font? It feels like reading a captcha. Is it only me?
