1:33:54wasenabled Per-pixel sorting on the graphics card. What, if any, software control is available via shaders, or is this just a hardware optimization that some graphics cards do behind the scenes to handle the opacity issue without a pre-filtered Z-buffer?

1:34:20Blackboard: The point of atomics

1:37:52anonymous519 What do you think of frame buffering like Vulkan's mailbox present mode to decouple the game update rate from the display device's refresh rate? You can render as many frames as you want, but only the most recently rendered frame is swapped in on vertical retrace

1:50:51anonymous519 What if I want my game to be deterministic, or what if my game does physics calculations and I need to update at a fixed rate for stability. Different people have different monitors with different refresh rates. Most people seem to then interpolate but this adds latency. Isn't mailboxing the better approach in this situation?
