Sir if you are using 32bit windows then your pc should've run with 4gb of ram . . Above that will couse blue screen . . İf its 64bit windows then you could use large number of ram gb (its more like what your cpu capable of . . İf your cpu was made for 32bit windows, then upgrading windows software to 64bit wont help) . . Long story short, if you are using 32bit, make sure you have max 4gb ram . . That was a huge issue for me long years ago, i stupidly upgrade from 4gb to 8gb ram but i was using 32bit lol (maybe im wrong, correct me if im wrong)

AS far as I know you maybe need to disable srp batcher if you want to use gpu instancing because both together dont work. Thats just maybe a thing, but which one of these two gives you better performance depends on your project.

[@000Gua000]

Excluding voice record quality, it's the best video on the topic of optimization. Great job! But couple things bother me. Isn't pixel light count only applicable to forward rendering path? While in different all lights are basically pixel light and adding new light isn't as taxing for performance as in formward mode. Also occlusion culling is actually bad for large open scenes. Cause there are basically almost no objects to effectivally occlude other objects and enabling occlusion culling isn't free. It does consume CPU resources, so for open large scenes you most likely that you'll get better performance by not using occlusion culling. Limiting camera render distance and masking transition to "nothing" with fog is another great method to improve performance. But you do need to blend that fog into skybox and there's different methods to achieve it, depending on skybox technique that is being used.

[@sketch3436]

Thanks, Gua I really appreciate it. I agree the voice recording was poor, and I didn't realise until later in editing and at that point, I couldn't be bothered having to redo everything. Regarding, pixel lights the forward rendering pathway is the only one that deals with them differently in terms of performance, so I wouldn't, be surprised if per-pixel light count only affects the forward pathway, however, I'm not too sure as the documentation doesn't give any explicit answers, if you any info let me know. I agree with what you say about occlusion culling, I probably should have put some extra detail in for that section. Thanks for reminding me about the fog masking technique I had completely forgotten about it, if I do another performance video in the future I'll be sure to mention it. Thanks again for all the feedback on the video I really appreciate it 😊

[@000Gua000]

Your welcome. Lightning fidelity and performance is the main difference between forward and rendering path. That's why most AAA titles deferred. It's brought app in every article on this topic.

I’m trying to use occlusion culling in my scene but i have some objects that have an animation that i want to be displayed, so I can’t mark them as static. Any advice?

[@sketch3436]

Occlusion culling is precalculated and therefore, if objects are moving the occlusion culling can not appropriately cull the objects, so I assume animated objects will not work. However, you can still set animated objects to be static on the occlusion variables and they will still animate so you may be able to correctly cull them by using an occlusion area: docs.unity3d.com/Manual/class-OcclusionArea.html

[@user-og6hl6lv7p]

Here's a few extra code optimisation tips for reducing garbage collection so you can free up memory: Don't use generic collections use arrays instead. Use for loops instead of foreach loops Reduce the number of new object calls inside of update loops, try creating vars/objects during the start procedure. Reduce the number of scripts containing mono-behaviours and try to incorporate a more polymorphic class inheritance approach. If you have an array of objects that you reference a lot use integers to refer to the index location of the object instead of copying the object every time you reference it.

[@ArunKumar-fx7zc]

Hi! i am new to unity and oculus go. I am doing a school project where i have created a scene and uploaded in the oculus go. I am experiencing lag whenever i move and i have animation the the scene which i also lagging. When i move my head, the scene takes time to load and the color is distorted ( all pink,green) before returning to the original surface texture. I am not giving a very detailed description as i am a beginner but do you have any advice to solve this lag?? I really need the user to move smoothly.

[@DanIel-fl1vc]

I've made hundreds of models and populated my scenes with them, they're all under an empty. If I wanted to use occlusion culling or shadow maps. Would you just select all of them, make them static and click some button somewhere. I attempted this in the past and it never worked, recall it even crashing at one point while baking shadow maps. The game runs fine in the editor but when you create a player and run the game in fullscreen it's about 45fps and 20 if you open a menu. I looked at the profiler and seems rendering is what is causing the lag, hiding the light and game objects increases performance by 50% so it's probably the real time shadows in the case of the menu it might be some script that is constantly looking for something. So frustrating but I suppose increasing performance is what you do at the end of the game's development.

[@sketch3436]

If the scene is really big occlusion culling and baking lighting can actually cause issues due to how big the file size will be, also especially with baking the lighting large scene take absurd amounts of time to compute. It's hard to diagnose performance without seeing the actual scene, but from what you say make sure you have LODs on your models to reduce the stress on rendering, additionally, if they are sharing the same material make make sure to enable GPU instancing on that material, if there is a lot of different materials/textures the might be causing memory issues that will slow down the scene so either reduce the texture resolution or create texture atlases for your models. Turn off shadows for models that are small and hard shadows over soft, also if you have lights that don't move set the mode to mixed (assuming your not baking the lighting). Also, since you have many objects make sure that you are not using 'gameObject.Find' commands in your scripts (unless on Awake or Start) as this command will search through all objects. For your menu make sure the UI is not using any extremely high resolution image when it isn't need. Performance is something you should be fixing throughout development, do not wait till the end. When you add new features always view the performance, if there is a decent drop you know that what you added can be improved, whereas if you waited to the end you will have no idea what aspects are causing the largest drops in performance. Hope this helps a little, I know performance can be a massive pain and there is no easy fix, the more you debug this stuff the better you will get.

[@DanIel-fl1vc]

@@sketch3436 Invaluable advice, I tried changing the sun light to mixed but didn't seem to affect fps. LODs for trees might be a good idea since there are lots of them in the scene. And I did use GPU instancing or I am using them. But if you make an object static it seems it ignores the GPU instancing. I tried which gave better fps and having the object be static improved the fps by 15% compared to GPU instancing so I guess it's preferable. As for the ingame menu, I'm loading it as a scene async on top of the current scene. So effectively two scenes are loaded at the same time. I suspect this is what's cutting the fps in half and not the menu itself. Because it's just some sprites and buttons. How could those half the fps. Do you think it's best to load menus in a separate scene on top of whatever scene you're in? Or should you somehow have the scene appear in every scene? Maybe make a prefab out of the entire menu or something.

[@554darren]

but can it run crysis?

[@snakeplisken4278]

How about best methods to change between large open world scenes?

[@sketch3436]

Larger scenes are always a lot harder to manage in terms of performance. I didn't really talk about large terrains mainly since I feel I'm not knowledgeable enough yet. The largest terrain I have worked on is 4km by 4km. For that scene the biggest challenge was to reduce drawcalls, so LODs were extremely important, every model in that scene had multiple LODs. Also, it's important to note that occlusion culling wasn't used, for large scale scenes the file size of the occlusion maps will actually lower performance. Those two were the two biggest things, however, we did use essentially all the tips suggested in this video with a lot of fine-tuning and testing. Transitioning between different scenes will either need a loading screen, perfecting the above techniques will lower the load time or you can dynamically load the scenes while the player in-game using allowSceneActivation or you can have it all in the one scene and use object pooling (this does mean you will need one longer loading screen at the start). allSceneActivation documentaion: docs.unity3d.com/ScriptReference/AsyncOperation-allowSceneActivation.html Hope this helps.

I'm a total noob. Lets say we have a weapon with all the internal parts. If you shoot with the weapon you can't see the internals, this still impacts on the performance? (I can't delete the internals because i need them when i disassembly the weapon in the game.

[@sketch3436]

The poly count of your weapon would be less if the internal parts were not present, therefore, it would be more performant. However, the impact on performance would be very minimal in comparison to other aspects (lights, not having LODs, reflections etc). I would not worry about the rendering of the internal parts at all unless you are really struggling with performance. Hope this helps 😊

You can change a camera's render distance by changing the far clipping plane, this can be done on the camera component itself. For code it would be: camera.farClipPlane = [whatever value you want (float)]; If you want to target specific layers you can use: float[] distances = new float[32]; //array for all possible layers float[3] = 10; //Change layer 3 cull distance to 10 camera.layerCullDistance = distances; Hope this helps

@@watercat1248 I would not recommend creating a script to dynamically change layer culling, since, every time you change a cull layer distance it has to go through every object in the scene to update them. However, what you are suggesting sounds exactly like occlusion culling. Occlusion culling is when the camera only renders what it can see, so if you're inside a room then all space outside the room will not be rendered. This is integrated into unity already and is really easy to setup Window > Rendering > Occlusion Culling, then just click bake the default settings are good enough. Note, that occlusion culling only applies to static objects. Documentation: docs.unity3d.com/560/Documentation/Manual/OcclusionCulling.html

Does bloom hurt performance? 😬

[@sketch3436]

Any post processing effect has to do some sort of calculation(s) and re-render so yes bloom would technically lower performance. However, out of all the post processing effects bloom is a pretty cheap one so don't feel discouraged from using a bloom effect even on mobile. Screen Space Reflections is the one you have to look out for that can make a noticeable drop in performance. Hope this helps :)

Add a tutorial on making pedestrians AI

[@sketch3436]

Thanks for the suggestion, AI would be a good topic to cover. Regarding pedestrian AI it is a lot easier than you think, here is a quick overview to help you out: Create NavMesh of the environment by setting objects to static and then navigate to Window > AI > Navigation and select ‘bake’. Create a pedestrian gameObject that has a NavMeshAgent (add from ‘Add Component’) this handles the movement. Then create a series of waypoints (empty gameObjects) along your streets we will use them to access their transform to make our AI move to. Using the NavMeshAgent property ‘destination’ you can set a location of where you want your AI to move to, you can also use ‘pathStatus’ or ‘remainingDistance’ to then apply the next waypoint. Here is the documentation: Destination: docs.unity3d.com/ScriptReference/AI.NavMeshAgent-destination.html pathStatus: docs.unity3d.com/ScriptReference/AI.NavMeshAgent-pathStatus.html remainingDistance: docs.unity3d.com/ScriptReference/AI.NavMeshAgent-remainingDistance.html For vehicles give them a ‘Nav Mesh Obstacle’, this will mean that is the player blocks the street path with a car than the pedestrian won't be stuck but rather just walk around the car. Nave Mesh Obstacle: docs.unity3d.com/Manual/class-NavMeshObstacle.html Although, if the pedestrians will never have any obstacles, then only create a NavMesh on the paths themselves this means you no longer need repeated waypoints rather just end locations. You can create different animation depending on the AI state using, Animator.SetBool: docs.unity3d.com/ScriptReference/Animator.SetBool.html For additional detail, you could add a Physics.OverlapSphere to the player to see what is within a certain radius of the player and then if the player is travelling at a certain velocity (i.e. speeding in a car) then make the pedestrian’s panic, i.e. change animation and make them run away from player etc. docs.unity3d.com/ScriptReference/Physics.OverlapSphere.html Hope this helps 😊
