                Don't even dream of reprojecting last frame depth for occlusion culling, you will fail!

Turned into a gist due to high likelihood of deletion. Also edited down to not include irrelevant trolling as to be useful to someone else considering Depth Reprojection.
Yes I know SSR and Parallax Corrected Shadowmaps work, but the consequences of errors in those depth tests aren't as high.
Lack of Generality (oh the irony)

You yourself state that this is general purpose engine, how is a technique that will have trouble with:

deformables (cloth, vegetation, skinned meshes, etc.)

    Twitter abuses all media file uploads, each type in its own way. If we
want to upload a good looking animation loop from some low-color,
high-detail generative art, we have to game their system's mechanisms.


don't upload a video file, they will re-encode it into absolute 💩


create a GIF, which they will auto-convert into a video file 😱


The frames of the GIF will be resized to an even-sized width using an
extremely naive algorithm. Your GIF should be an even size (1000, 2000,

                Proctored exams will not be tolerated
              
          
    Dear Concordia University,
I am writing to you on behalf of the Concordia student body regarding the final exams and the decision to use online proctoring. We are urging you to change your decision about having online proctored exams. For many, this is an appalling invasion of privacy, a security risk, a demand for students to trade their morals for a grade, and discrimination against the less fortunate among the student body. In addition, over 7000 thousand Concordia students are against online proctoring.

An invasion of privacy
Forcing cameras and microphones into the homes of students is a violation of everyone's online privacy. For some, this might not be a huge concern, but for many others it's spying on
