I was always so worried about poly count, always trying to keep it to a minimum, but I love it that in this video you went from 0.5 FPS to hundreds without reducing a single polygon, always kept with those 21M.

[@Domarius64]

There are various bottlenecks to be aware of, polycount is still one of them, but the aim is to solve the one affecting your particular situation.

[@xomvoid_akaluchiru_987]

@@Domarius64 why not apply all of the performance techniques at once? As soon as you solve the original problem, shouldn't you apply the other techniques?

[@Domarius64]

@@xomvoid_akaluchiru_987 if you have infinite time, sure, you can do everything. But in the real world you are always making trade offs to get something produced in a way that still turns a profit.

[@xomvoid_akaluchiru_987]

@@Domarius64 Ok, time constraints, sure, but if a product is finished and you're coming back to fix some things then I don't see why implementing all of them would be an issue if the product really does benefit from it. If it doesn't benefit much then I just trust myself to have common sense and see that it's not worth it.

[@Domarius64]

@@xomvoid_akaluchiru_987 that "extra time at the end" literally never happens in game dev :) you always end up releasing the game when its good enough, not because its finished, because it never is. And so you cant justify spending time on things that have no tangible benefit - remember, you said "why not do all of them?" Well, thats why not. If the game runs on the target hardware acceptably, there is no reason to optimise. Plus when you say "why noy do all techniques" like there are only 5 or something. Every different programmer could know any number of techniques they learned about somewhere, too numerous to list, you cant just "do them all". And more importantly, those changes will not have zero impact, there will always be knock on changes related to that, and plenty of opportunity for new bugs to be introduced at every step of the way, all which will have to be fixed, taking even more time. If its working, you leave it alone.

[@captaincommando9839]

insanely useful considering i was using multiple materials for flat coloring instead of just using a texture.

[@dertobbe1176]

You accidently exolained what happened to my scene. Ty I got it ans will make use of it ❤

[@Reeality09]

Btw. GPU Instancing will NOT work, if you have enabled SRP Batching in the Render Pipeline Settings. The SRP Batching is also better in performance reasons, because your gameobjects do not need to share the same Mesh/Material.. just the same Shader.

[@antonovivan3008]

I’ve never tried to measure the difference in performance by myself. But according to what people write at Unity forum, SRP batcher is generally slower than static batching. It has less memory footprint and easier to use though. And in some cases GPU instancing may be more efficient than SRP batching. In case of dense grass field made of 1 instanced mesh, for example.

[@disdathit]

Nice vid, thanks 😊

[@gddhyper4913]

Back after lots of months and now i understand

This is a very nice format to explain performance though: gradual improvement.

Best 5 min ever spent!

[@StarkTech47]

Awesome video, short, detailed with very good explanations and demonstrations, great job ! I have a question, for the GPU instancing on the material. We see in the video all building moving but how did you do that ? I suppose it thanks to compute shaders or by C# script ?

[@a6gitti]

thanx for these tips

This is optimization-heaven

[@baldipogchamp8926]

Been making jam games in unity for 2 years now, did not realise how important the Static tickbox was. Never used it before, changing that now!

awesome!

Loved it !! when i was about to upload my game i searched this and all the top results were just making the game look like potato 🥔 and today i found this video :) honestly KZbin should push this video more...

GREAT CONTENT

[@zlotey6485]

I have a question about your 3rd point. 4:05 What should I use for organic material? For example, grass, trees, bushes, etc. - but these only "move" by a shader. should I use GPU instancing or static mesh?

[@LofiDev]

Good question, static batching should work for them. When I say no movement what I mean is that objects transforms should not change. Any movement done through the shader is fine.

[@ethankendall7575]

Thanks this means a lot to me when I am developing on a Intel i5 2gb gpu appreciated

Amazing Vid, 824th Subscriber

[@mohammedmurad7725]

Thanks, REALLLLLY THANKSSSS.

[@Foxtrot6624]

Absolutely fantastic. I had no idea that marking an object as static actually did anything without scripts or rigid body’s applied to them

[@unknownx4295]

Thanks, it helped

[@potaterjim]

But what about occlusion culling? If you've got an interior level made up of several walls and rooms, is it better to user lots of smaller meshes and occlusion culling? Or what about the middle ground: making each room a large static object, and then using occlusion culling to turn off entire rooms at a time?

[@farukonder8937]

Thank you :)

[@vikaskumarpatel5017]

Thank you for such a single explanation. Amazing! I do have a few questions though, 1. How much duplicate objects with the same mesh, materials and settings? 2. Are duplicate objects different draw calls? 3. Are duplicates affect the CPU/CPU in the same way? For eg. two buildings with different materials which has the same mesh and two building with exactly the same mesh and material. 4. What about complex meshes? What is people just use this technique on a mesh which is complex? 5. What if I mark an object Static and turn on GPU instancing? 6. Also, fbx vs obj in this case?

[@jamesthiel5721]

Well, make a PREFAB of any multi-duplicate object you are planning to use. So 1 object with it's material(s) for ex. (note: prefabs can be a parent object with "nested child objects" too) Set it correctly, (Optimizing/combining, Static or GPU instancing) and use that prefab to build/compose. Make a second prefab for the different materials using the same mesh.. it's another batch for each material/mesh relation if I understand correctly. Unity will batch each of these separately but they will batch since a prefab is made for optimization and for batching. Complex meshes: just like the multiple window objects, you should combine/join all the objects like so: Static and or whole unbreakable objects should be combined/joined as ONE mesh. (NO need to connect all vertices like a sphere is). the breakable object would need to be seperate chunks objects which each a rigidbody component. Separate moving parts (animation) for car-wheels, windmills for exemples. nested in a parent object. Cars probably are all non-static so use gpu instancing. But not for the windmill structure -> static structure, and just for the rotating object -> gpu instancing. (although: you probably not gonna spawn 15 windmills so no real need of batching these. lol 🤣) Characters: usually one mesh for the body skin. for more life: 1 mesh for each eyes, and even more: the tongue and teeth/gum. Then customization of each cloth and bags, wearables ... is another story.. diff. approaches.. 5. GPU instancing allows object to move while Static is static cant move. there is conflict right there.. but I don't know try it. 6. I have no clue which is best.
