This is essentially just the original Minimal D3D11 codebase with 8x MSAA added. However, since MSAA only smooths triangle edges and does not affect textured surface interiors, texturing is removed to isolate and make the effect of MSAA clearer.
In short there are two parts to it: 1) Create and render to an MSAA texture rather than your typical rendertarget/framebuffer (note: the depth buffer must match), and 2) [Resolve](https://gist.github.com/d7samurai/d74299f8bcadcb9cb0686
An example of SDL3's new GPU API being used with Slang in the Odin programming language, supporting hot-reloading of the shader. This example is a modification of existing API examples:
The SDL3 GPU API is initialized by first telling it which shader formats you are able to provide it. Based on that list, SDL then selects the

Ultra-compact sprite rendering code with example frame animation logic. This release contains tech bits from the upcoming SuperNeo™ 2D game engine and includes anchor/pivot point, rotation, color filtering, alpha blending and built-in antialiased point sampling. As usual: complete, runnable single-function app. ~150 LOC. No modern C++, OOP or (other) obscuring cruft.
Sprites are rendered back-to-front (AKA "painter's algorithm") in the order they are submitted, as one draw call. The provided setup employs a single texture atlas containing all the sprite graphics.
The renderer is "im
Example of how to capture CPU counters with ETW on Windows, perf on Linux or kperf on Apple.
Using ETW needs somewhat recently updated Windows 10 or 11. Not sure about exact version.
Currently tested on:
