Don't take this the wrong way kvark, but is Vulkan Portability really the long term answer here? Do we want everybody to be writing Vulkan code? It's unfortunate that due to the mess of tilers, Vulkan got way more complicated than

From what I can tell, there's no library to parse the full range of ISO 8601 in Python. The standard string that people claim is "just ISO 8601" ("YYYY-MM-DDTHH:mm:ss.sssZ") is not full ISO 8601 compliance. ECMASc

Game AIs are terrible for neural networks. Game designers want the ability to micro-tune difficulty and decision making to pace the game experience and the curve, and often times what's engaging for players is a simple model they can

Yep. Though it's a lot trickier than just bind/unbind, e.g. if you have a VAO bound, you need to unbind the VAO before binding a vertex buffer, or else you might have overwritten the VAO's vertex buffer binding slot. And I&#x

DSA is Direct State Access, it's an OpenGL extension to remove some (not all!) of the more annoying binding state. https://www.khronos.org/opengl/wiki/Direct_State_Access

I do recommend writing some DSA-like helpers for OpenGL, its global state is annoying to wrangle and not that meaningful to the actual GPU. The tricky part of OpenGL is understanding when something is a bad API accident and when something i

The complexity that Vulkan introduces is not just the extra code, it's a substantial rethink of the mental model of graphics that involves a lot more precision about things like synchronization, and baking of device state. Those who ar

My understanding is that ATI's management bungled the software aspect, fell super behind on driver development, and gave NVIDIA way too much time to catch up, but you'll probably have to talk to someone that was there at ATI to fi

The GameCube is not, generally, resolution-agnostic. The internal framebuffer is 640x528 pixels wide, and the hardware has this hardwired in certain places, like the VI/scanout subsystem. Games themselves even allocate the scanout buff

That's partly because we got tremendously lucky in how the hardware sends data. Unlike some newer GPUs, the hardware has dedicated memory for the Projection and Model-View Matrices, and the vertex pipeline is fixed-function. Dolphin is

If a post processing filter takes 18ms to complete, uncontested, you can't "pipeline the shit" out of it. You can get a frame at least every 18ms. Adding more load won't magically transform throughput into latency, it wi
