Using DOTS to Optimize GameObject Gameplay: A Case Study from Survival Kids
This talk provides a few examples from a real game showing how performance-intensive paths were optimized. As I've mentioned before, I love reading or watching these optimization stories from the "tech trenches," and I definitely recommend checking the recording later.
It covers a few techniques, including how to:
- Use Entities systems to update MonoBehaviors
- Do position checks effectively
- Use a Transform Access Array to update Transforms fast in worker threads
There were only 3 cases, but how the talk was delivered is at a super high level. Kudos to Andy for the excellent storytelling

Sounds like the exactly same advice from the last year about shader variants and how to optimize it. Nicolas goes into more details how keywords and variants work

Use ifs in shaders instead of keywords. Profile it. It might be better for your case.

It was quick overall. Not as rich in advice as previous years. Especially 2017-2019 talks on the same topic, which are my all time favourites.
Make sure to check them, here is my overview of these talks: https://gamedev.center/best-optimization-tips-by-unity-engineers-at-unite/

Talk: Understanding Unity Memory
I recommend checking the recording as Richard gives a gentle intro into how memory works. It must be interesting if you haven't learned it before.
There were a few slides that caught my attention:
- how to use unsafe to allocate your data sequentially in memory in his particular case
- other GC in Unity used for assets etc
- when to split big structs

The Unity Engine Roadmap
It was impossible for me to share live at Unite all the great features they have planned as it was so packed. Check the recording and you'll definitely find something interesting for you.
I posted the most exciting stuff for me live on the 19th of November, what do you expect the most from the roadmap?

Optimizing Burst matrix multiplications
A deep dive into optimizing matrix multiplications. A story of multiple optimization attempts, moving from basic implementation to hand-tuned intrinsics.
Key takeaways from the optimization journey:
* Switching to Unity’s Mathematics package (SIMD-friendly) immediately gave a massive boost over standard C#.
* The Low-Hanging Fruit: Using FloatMode.Fast allows the compiler to merge instructions into Fused Multiply-Add (FMLA).
* Reinterpreting NativeArray<Matrix4x4> as float4x4 helps the compiler see the data layout more clearly, reducing instruction count.
* Utilizing Affine Matrices (since most game objects don't use perspective projection) allows you to skip calculating the 0,0,0,1 row, saving significant cycles.
* Using Intrinsics and float4x3 to pack data tightly into vector registers.
This is a must-read if you are working on high-performance physics, skinning, or animation systems in Unity.
