      I have nothing against C#/.NET. I was just commenting on this particular optimization and the root cause (OOP practices = fine grained locks, fine grained allocs) that requires optimizations such as this.

      There's absolutely nothing wrong with a GC. The problem is languages, as Sebastian says, which impose OO-everything -> fine-grained allocs. C# would already be great if you didn't need to alloc an object every 2 lines of code. Stack alloc support is very limited

      The new Burst compiler's C# subset doesn't have ref-types, classes or GC, only value types and structs and special container types (all AFAIK, haven't played with it yet). Mainly useful for the 'inner loop' type of stuff I guess. Don't know yet how it interacts with classic C#.

      It's paid off and carved them a niche (or... cavern? :) But ultimately their choice also limits them. It'll be interesting to see how HPC# pans out, but I don't think it's going to solve their AAA problem

      I am positive we will see some a pivot from Epic. I mean, they HAVE to.

      A meteor has hit Epic and you’ve been chosen to run Unreal Engine. Craft a pivot strategy and explain it in one tweet.

      Oh, fun! New scripting language that compiles to ISPC. Limited in scope, but fast.

      What is the problem corresponding to this solution? 🧐

          Problem = programming is not fun enough. Solution = use ISPC everywhere :)

          ISPC is heckin' cool; but it isn't applicable to very many platforms is it?

          Better perf for handling of lots of objects like crowds, etc. Example: Script to randomly scatter trees, select models base on terrain height, etc. I guess the new particle system can do some of this stuff.

          Successful data parallel apps like Houdini do this with graphs with code per node. Seems like this could be doable in unreal ala shader compilation.
