How To Render 2 Million Objects At 120 FPS

Project files: github.com/Matthew-J-Spencer/...
Let's discover the true potential of Unity by pushing its limits. In this video, we'll explore a variety of techniques, from straightforward tweaks like data-oriented design, to more advanced methods such as direct GPU rendering and compute shaders. Join us as we uncover the power and flexibility that Unity has to offer!
Some techniques used:
Unity DOTS (burst, jobs, ecs)
RenderMeshInstanced
DrawMeshInstancedIndirect
Data-Oriented Design
Avoiding extern calls

Let me know if you'd like to see anything else benched, or whatever else you'd like me to cover :) My specs: Ryzen 9 5950X 16-core GeForce RTX 3090 64GB Memory

[@sima19995]

How about the forgotten Quaternions?

[@gemidytwins]

Sure, mesh baking vs instances vs gpu instances, material batching, light baking, all these stuff. Also triplanar mapping with 3 textures, with 6 textures (albedo+normal), simple vs. with blending. LOD solutions: unity lod, vs other solution (like progressive mesh) + billboard + impostors. All these are very interesting.

[@fourthgearvibez4343]

There's no way my laptop with 12 fps on blender has quadruple your space with half of it being free and STILL only runs at 12-25 fps on blender.

[@ChronoCZ]

Hey, cool video. I think you could squeeze out more performance out of mono behavior game objects by parenting them to some object. Maybe add that as a benchmark case. I believe that incorrect hierarchy might cause a few % slowdown.

[@pieTone]

Wait, I don't get it. Are you mental checkpoint?

[@purplexy]

I love how you prepare all these scenes to make them look so appealing and eye-catching for us. Good stuff, keep this up! 😛

[@Tarodev]

The poor bitrate couldn't keep up when it reached 90k cubes >< Glad you enjoy the visuals :)

[@fabiencrescent6503]

Increased Performance Strategies : 1:30 - Manager script instead of monobehaviours (only 1 Update() call) 2:49 - Reducing external calls (Caching position instead of asking repeatedly the transform position) 3:50 - GPU Instancing 5:21 - Multi-threading (Unity "Jobs" & "Burst") 6:58 - ECS (part of Unity Dots) 8:29 - GPU Instancing Indirect 13:09 - Camera Cache

[@Tarodev]

Awesome. Thanks ❤️

[@fabiencrescent6503]

You're welcome and thanks for helping Unity devs ! 😉 I'm having trouble with rendering 9 chunks of 16x16x10 cubes for a simple prototype (I didn't find the way to implement simple GPU instancing..) so I don't know yet how to use all the work you did but it seems really great !

[@lavisch837]

Man, I really want to get into DOTS. Really seems like it's the future of Unity development.

[@Tarodev]

More performance than you could ever really need, to be honest

[@mrslake7096]

I think it's not worth the cost of time & complexity for most projects

[@Tarodev]

@@mrslake7096 Yup, 90% of indie games will never need to touch it. The ones which do will most likely only need jobs & burst. Even for a game like vampire survivors, ECS is not really a requirement.

[@MuhammadHosny0]

not worth it unfortuantely

[@maxfun6797]

​@@MuhammadHosny0 it's absolutely worth it if you want to make games with multiplayer and mlagent ai. Infact it is necessary, my game lags so much without it, and I used a small count of very simple ai. Yes without these 2 things, it's probably not worth it. BUT... dots isn't actually hard to figure out. The hardest thing imo in unity is multiplayer (but only because my game is complex), everything else takes a day to learn.

[@gamecreatorc]

I'll have to keep this in mind. Love what you do for the community!

[@KonaiNobi]

WOW!! This was a fantastic video. I've been dabbling in learning Jobs+Burst but this demo was just amazing, gonna have to put more effort into getting my head around that .

[@MidasButSilver]

Your vids are amazing; fun to watch, very interesting and always filled with info. Also love that you always include similar scenarios with the different tools we have available to show their drawbacks/advantages

[@simoncodrington]

This one was fascinating mate, really liked the visually focused explanations, showcasing the tangible FPS improvement along the way.

[@COL4NTUOMO]

Man! I think you are one of the best unity creators in yt.. Your explanation is clear and you really know what you talking about I would love to watch a serie where you create a game from scratch using all those techniques

[@minhmino6445]

your video is really great , help me learn a lot, and seeing 10k objects on screen at the same time with high fps is so awesome and fun to watch

Amazing video again, I was wondering how to do gpu instancing and this really helped :)

[@vdvgames]

Great vid! :) Was always undecided over individual scripts compared to a single loop.

[@riddheshzaveri8103]

Wow, its so mind blowing that often its not about the engine but the developer himself regarding how much can you extract the performance out of the engine.

Can we expect some ECS DOTS Tutorials?

This could be in the cards

[@Louis-nh1ei]

@@Tarodev I was going to ask the same thing ! Just want to push this haha

ECS DOTS is dead. It’s never coming out. I promise you. Not worth investing in

[@jubinjajoria2870]

@@gavintantleff I respect your opinion, but you can't just put your opinion as facts. I would like to hear some stats/facts/ research that can back your answer.

[@gavintantleff]

@@jubinjajoria2870 the fact that most dots libraries are not getting any real work done, there are no updates or information about dots, deadlines missed significantly. Of course I can’t know that Unity is dropping it, but it sure seems to me like they are. Why they don’t just come out and say it, I have no clue. The only dots related feature that seems like it’s being kept is tasks and burst

[@rolandinnamorato1953]

love this style of incremental enhancement.

[@supairo6539]

This is actually very helpful. I am currently working on a Game that has to update the position of many thousands of GameObjects. I will definetly try to implement some of these things to boost the performance.

[@the0neskater]

Incredible video, well done!

[@iHeartGameDev]

Taro, you explained all of this so well!! I admittedly don't know a single thing about ECS, Dots, GPU instancing but even from that position, I came out of this seeing the real benefits of those systems. Awesome job and love having you back making vids :)

Insane how big difference some of these technologies make. It really opens up options for new games or features while keeping really good performance.

[@Hazzel31337]

i knew from jason weinmanns gamedev show that you should do your own game loop instead of the monobeheaviours and that ECS ist fast, but your video is like a massiv sun shinning light on this topic and helping me understand, 100/10 quality content! thank you so much

[@edmundjr.salcedo7854]

This is the best AD for Dots and ECS

[@YouCodeThings]

Fantastic - great examples!

[@alaslipknot]

Very insightful as usual, thanks a lot! there is really not a lot of good in depth resources about doing GPU Instancing, it would be amazing if you can a video exclusively about that.

I can do that :)

[@Louis-nh1ei]

@@Tarodev Please do good sir :)

[@YoupiMatos2]

@@Tarodev I'm gonna second this suggestion, the lack of resources is really sad, it feels like there's an abyss between a mid level Unity developer and an advanced one, because these techniques are only shown through examples but barely explained in detail. Please do! Thanks in advance!

Thank you! Thank you! Thank you! I never knew of GPU Instancing Indirect! Bloody hell, that is a game changer for our Voxel Engine, so glad to have found your video and can't wait to implement this indirect instancing. 😊

What an excellent video! Advanced concepts, smooth implementation and succinct. I'd love to have this exact same thing for Unreal Engine and to be able to compare both, but I see you focus exclusively on Unity.I've got a bit to learn about Unreal and shaders before I can do this but I definitely will at some point. Thanks for sharing your knowledge!

[@WeslomPo]

Caching variable does make a difference. Especially on mobile devices, where we don't have much rich instruments to optimize our projects, and we need to be sure that it work across multiply devices.

[@swalscha]

Thanks for this insight on performance! It's a huge aspect of development I'm personally interested in :D If you need new topics, you could share tips to reduce the final data volume used by the build (sometimes I see games that take so many Go that I don't even understand how they have reached so much! Even considering a lot of textures midmaps and full assets integration).

[@Tarodev]

Damn, that's a great video idea. It's something I could also learn a bit about, too. I've done this a few times on previous project deployments, but I feel there's a lot to learn.

Video idea related to this: how to properly benchmark & profile. Recently there are new tools like memory profiling. A deep dive especially by you who has shipped actual titles would be very interesting. Thank you again!

[@kaasronald3623]

great video as always. super useful to get started choosing optimisation techniques. It's so tempting to implement ECS once it enters 1.0, even for just the sub-scenes, but it's probably way too risky for games that release within 12 months... >:(

[@jonasRedStar]

thank you, I have learned A LOT

[@enitalp]

Very nice video, this is the way I always work, Test everything , learn the best practices, from actual experimentation. I’m caching everything, coded for years on mobile/ switch, and those caches have an impact on a 10 to 20 times, slower Cpu. Input. For exemple is costly, more on some hardware. Plus it’s not just the call of an external function, taking time, it’s also the need for the cpu to trash the data and code cache. Making the functions coming after slower, because of it
