There are several things wrong about this video. Mipmaps don't reduce memory usage, they actually increase it. They create smaller versions of the texture and all of them are uploaded to the gpu(including the original texture). Then the gpu selects the best fitting mipmap based on the size of the object on screen. According to unity docs, mipamps increase memory footprint by 33%. But they increase the gpu performance by allowing the gpu to draw a smaller texture. This is still only gonna be noticible if you have a GPu bottleneck. They won't provide any performance benefit if your bottleneck is on CPU. Vsync forces the engine to render at the same pace as your device display updates. For most monitors it's 60 frames per second. Disabling it makes the game update as fast as it possibly can, eating more resources for something we will not even see, because the display will still update at it's regular rate.
I’ve actually seen so many videos that are similar, they just say either occlusion, no post processing, light probes and remove all reflections, it’s kinda annoying when I’m working so hard on a couple aspects of a game and want a quick optimisation guide that works and is stable
For me only 3 things actually made difference : - Generating lightmaps - Reducing max clipping planes - Reducing texture size. If you have a very huge environment, don't forget to use occlusion culling. It makes a huge difference!
As PC Dev, if you are going for something like a dark souls world, or any kind of seamless open world, occlusion culling will stress the CPU way too much. The only option I found was working for us, is to disable (via code) every object that is not needed. Disabled objects are for unity almost as if they would not exist. They cost nothing (except some RAM). We even disabled Occlusion Culling, have realtime lightning only and got from 60fps by just disabling objects. Also this is the Nr.1 method to profile GPU performance. disable groups of objects until the performance gets better.
@@nilla_studios unity has OnBecameVisible and invisible functions which run, accordingly to the name, when object is in the camera vision or not. Pretty useful thing, but when you have a lot of objects(like terrain and it's visual components, like grass and etc), I usually set invisible collider and when player enters/exists it, I set SetActive to true/false
@@nilla_studios We use Volumes, basically the same thing like Triggers, but I wrote my own System with octrees and a custom overlap function for absolute maximum Performance (it's overengineered, the physics triggers will work just fine)

It's great info but wont be enough if you plan to have large and detailed scenes or use high poly assets. If you need serious gains you should also look into instancing all the props in your maps (trees, rocks, buildings, etc.), use pooling to reuse GameObjects as much as possible, implementing LOD, occlusion culling, optimizing your 3D assets (mesh, animations, textures) and profiling your game/code. Your camera style also has a huge impact (top down vs 1st or 3rd person) because of the view distance. Creative use of fog can save you a lot of perf. Now, why this simple scene isn't already running at 500fps is puzzling.
bro is there any tutorial for all the above things you mentioned? I am working on a 3rd person shooter. Please give me some reference for the above stuff you said on your comment.
@@StressedProgrammer did you find any tutorials? Im making a 3rd person RPG in unity in URP pipeline, it runs good until I add some NPCs and objects lol
yea for " instancing all the props in your maps (trees, rocks, buildings, etc.), use pooling to reuse GameObjects as much as possible, implementing LOD, occlusion culling, optimizing your 3D assets (mesh, animations, textures)" you can watch a tutorial by "CG Dealers" on youtube. the other things mentioned in the above comment are project specific you have to figure them out your self
This tutorial is actually fire ! I have watched hundreds of them but with this one everything is on spot. And the example with an asset from unity asset store is exactly what we do, buy an asset and then try to optimize it. Thank you !
when i saw this video thumbnail i thought it was clickbait but no. its actually working yoooooooooo! liked u have very high quality videos and i couldnt believe
Best tutorial on optimization. If it's possible, Can you start a mini series with different 3D projects and describe each optimization tool in a detailed manner rather then doing all of the stuff in just one video. There is a lot of things that need to be covered in depth. Anyhow thanks for sharing your knowledge with us.
THIS IS THE BEST VIDEO in youtube for game /FPS optimization. My prototype went from 32 FPS to 200 FPS after implementing half of the suggested configurations (I am using Unity 2017 so not all are available ) . The video was short, focused and packed with IMPACTFUL recommendations. Look no further, this is the one. I would appreciate a video on tweaking lightning as it seems like the major driver of the improvement in my game. THANK YOU !
This was really good. I used it on a more complicated game and got good results. I had trouble finding this information in other tutorial videos. I would recommend instead of saying "we can turn that off because we don't need it" explain why it's not needed in this case. Thanks.
Excellent tutorial. Thank you! One small note - I would appreciate a timetable of all the subjects you've covered in the tutorial, so it can be easily found upon return.
Your video helped me so MUCH! You explain things clearly telling me where to find them and my world is running so much better now! Still looking amazing! Tyvm!!
From beginning I did not believe this because the solution was soo simple but this guy legit brought down my batches from more than 2k batches to 200 batches as min -> 600 batches as max and my level still look great, thankyou so much dude
Also delete the colliders for objects that or in places that the player will never get near and also turn on static shadows for things that do not move and turn off shadows for things that you don’t really see or you won’t notice if the shadows are off, and if you make stuff in blender, delete the back sides of stuff if you’ll never see it in your game, like I made a cylinder in blender for one part of my game and I deleted entire back half of the faces because you’ll never see that side
Very helpful! How would you compare the performance of the shader Mobile/Diffuse to the shader Mobile/VertexLit (only directional lights)? Is the second even faster?
My fps was a bit low when I play without maximizing it (in the editor) but after playing on maximized my fps got double...Can anyone tell me the reason?
This is pretty standard stuff, but its very effective even in more detail oriented 3D game environments, 2D and mixes between the two. I would have not considered the UI part so you won a subscriber :D.
Along with these you can also use occlusion culling for more better performance. However, I love your video. Nice and more concentrated on the most useful settings!❣❣
It definitelly helped reducing the size of the game after build. from 200 mb to just 87 mb also it reduced light baking time. Sadly I can't test it on my bad phone, cus it's battery expanded, so I can't say how much it helped with the lagg.
If u se collission detection to discreet collision will NOT work gor fast moving objects. If yoy still want to have that keep it as continuos dynamic or interpolate continuos
A good video helped me a lot, but I have a question saving my project to an APK or .EXE file, will it keep the same fps? Or does it only work in the Unity editor?
Awesome video, need to try it! One question upfront: How will the baked shadows from the environment behave? For example, will the characters still dynamically / in realtime get covered in shadows when they walk below the trees under their shadows?
tried all your solution still when i play my self made game on my pc it turns into plane and overheats.. however far advanced games like just cause 4, far cry 4 etc runs smoothly in my pc... some youtuber says its just problem with unity engine while other says unity has fixed this issue... nobody tells how to fix this
The video title includes "SRP" which should mean Unity's Scriptable Render Pipeline, but as far as I can tell this is using the built in renderer. I wouldn't count on being able to have your players use GPU instancing either, unless they are identical objects. Some of the tips are okay though
Great tutorial...But one question. Making game object as static will increase the build size.. any suggestions... To reduce build size apart from texture reduction. Thank you...
What are your specs? I can only get 340fps on a fully empty scene with my laptop i7-9750H and GTX 1650, I'm not sure if I'm using that or integrated graphics, I'm sure with all those settings you're almost close to your baseline performance and my settings are with a maximized screen which performs better, I have a FHD display.
I'm getting close to your numbers in a fully empty project thought, some 500fps jumps, but I guess your pc might be better or unity has become more bloated from 2019 to 2021 version
I'd love more optimization tips on other parts of the rendering tab. For example, how do you make the game stop rendering things that are off-screen without causing texture pop-in when you look back at those things?
All I got is a flat terrain model that's bare and one simple plane which puts the vertices about the same as yours. For some reason I'm hitting between 68-72fps and at a lower resolution too. I have an RTX2080 Ti, why can't I hit the same fps as you with these settings? Nothing I did in this video increased it at all, I know there has to be a reason behind it....something is capping the fps I hit in Unity. Do you know what's causing it?
Have you tried changing the scene, maybe try some other projects from unity and see if it causes any major changes to your fps.. im not sure what might the problem be..
@@TheGameGuy Yeah...strange, I tried that and I'm hitting the same FPS no matter what I load. Something is obviously capping my FPS but I don't know what, I checked the Nvidia Control Panel and I don't have a global FPS cap set...
could you tell me your PC specs other than your GPU? maybe something's capping the FPS as u mentioned.. ill look into it and let you know if i find something..

And to those saying that video is misleading due to small window size, I want to mention that upon maximising the game, the FPS increases so basically what is shown is the worst case scenario. If he had maximised the window at the end of the video, the FPS would have been much higher. So stop complaining.
As a complete non-developer who is simply interested in the process of game making, especially optimisation, as I find more and more devs are releasing poorly optimised Unity/Unreal games vs what the game actually does, I have to ask…considering the power of our hardware now, why does such a simplistic PS1-looking scene that he uses already cost so much performance pre-optimisation?? It seems bizarre to me.
He brought my frames from 60-90 for my decently detailed game in the first 3 minutes and II kept most of the high quality settings. Thanks man!
before I watched it, I had 40-60fps no 20-60....
@@FunkyFrag maybe the problem is in Occlusion Culling? If you are in 2D or in 3D, where you have tons of objects, then it only slows down performance
Not to be mean, but just reducing graphics settings is *NOT* optimisation
