are often still used instead of MiB, GiB, etc. This was originally known as a megabyte-indicated with MB-but that's now supposed to indicate 10 6 bytes, matching the official definition of a million. MiB is the suffix for mebibyte, which is 2 20 = 1,024 2 = 1,048,576 bytes.

What's a MiB?īecause computer hardware uses binary numbers to address memory it's partitioned in powers of two, not powers of ten. BRP has to do it at least three times, because of its extra depth-only pass, plus once more for every light besides the main directional one. URP has to do this twice per frame, once for shadows and once for the regular geometry. For 40,000 points that's 2.56 million bytes-roughly 2.44MiB-that has to be copied to the GPU every time the points are drawn. A single matrix consists of sixteen float numbers, which are four bytes each, for a total of 64B per matrix. Sorting, batching, and then sending transformation matrices for 40,000 points to the GPU takes a lot of time. Profiling a build reveals that everything takes about four times as long, which makes sense. Profiling a build at resolution 200, without VSync, BRP and URP. In my case the average frame rate dropped to 10FPS for a BRP build and to 15FPS for a URP build. Let's begin by doubling the maximum resolution of Graph from 100 to 200 and see what performance we get. We might be able to reach 60FPS at resolution 100, but how far can we push this? And if we hit a bottleneck can we push past it by using a different approach? Resolution 200 The amount of points is equal to the resolution squared, so doubling the resolution significantly increases the workload.

The higher the resolution of our graph the more work the CPU and GPU have to do, calculating positions and rendering cubes. This tutorial is made with Unity 2020.3.6f1. This time we'll use a compute shader to significantly increase the resolution of our graph. This is the fifth tutorial in a series about learning the basics of working with Unity.
