When launching the game, I have very low performance (20 fps) When I profile with “Stat unit” command, It doesn’t show the line GPU and the line RHI Thread is very high. It can even merge materials if you tell it to, to reduce draw calls even further. Early rendering of GPU Profiling - Lesson 2 of my Unreal Engine Performance Course Tutorial Archived post. When I type stat StopFile it does nothing, it doesn't even suggest it in the list of commands. Let’s say you’ve found that your project isn’t performing well. Hi all, A bit confused here by the CPU profiler in the Unreal Frontend application. Early rendering of depth(Z) from non-translucent meshed. The Unreal Directive is a passion project that aims to provide quality and reliable resources for Unreal Engine developers of all skill levels, free from misleading practices or shortcuts that could result in tech debt. On the flip side, if that value is set to 0, stat gpu values start to match the stat unit gpu time. I wrote about this when trying to reduce my Dedicated GPU usage in my article How to Improve Texture Streaming GPU performance in UE5 over 20% increase on GPU memory [Solved] In this file I found D:\Program Files\Epic Games\UE_5. Can someone help me out? aeonsparx (aeonsparx) August 20, 2018, 1:59am 4. A useful tool though is the ~ key to open the console and type Stat GPU. The problem is that the bottleneck moves around, so those stats aren’t all that useful. Several stat commands (GPU, game, etc) don’t work, and freezerendering don’t work. The editor will show particle counts, in editor, per emitter how can one see the particle count in the scene at any given frame for all NS emitters, for example any I think that those can also provide good informations. gpu, profiling, question, unreal-engine. The amount of GPU time “stat unit” reports is in the 13 ms range, but when I add up the top-level timings in Profile GPU, they only add up to 6 ms. Figure 17. Open C:\Program Files\Epic Games\your-version\Engine\Config\ConsoleVariables. Previously, this processing would happen in the frame the level became visible and could generate some noticeable hitches while doing so. (should restart your unreal editor to see the result) if your GPU is AMD Radeon, check the Radeon Overlay, or You can also use "Stat GPU" to see a further break down. currently, I can see that my test project is GPU bound with stat unit command. Hi, any suggs on the best way to profile really heavy niagara systems? I see a list of stat options in the viewport, which of main interest is Niagara, which shows me how much GPU memory is being used. to choose best possible framerates as begin of the map with DLSS enabled. The tasks channel gives you more info when hovering over the “Waiting for Tasks” events. Its a house; an interior with surrounding landscape. Do a ‘profilegpu’ and have a look at where your GPU costs are. HZBOcclusion to 1. If I generate a world at the start of each new game, the world generation process usually takes a few hours, but has before taken almost a day. I am seeing only a total of 7. With something like ‘stat scenerendering’ slate can go up 10ms, but that’s not what I’m doing. Unaccounted GPU. Changing occlusion to software occlusion and precalculated visibility just moved the bottleneck, no However, my slowest thread is pretty consistently “Draw”, which as far as I know is mostly on CPU (and it would make sense, my CPU is pretty old, my GPU is pretty new). I’m using ProfileGPU and “stat unit” for profiling, but I noticed that their GPU information doesn’t seem to match. anonymous_user_2df62536 (anonymous_user_2df62536) September 10, 2021, 6:36am Stat RHI will show you vram usage iirc If not that then stat scenerendering or stat scenememory Question about the gpu VRAM Members Online. I try searching online but I don’t think I’m using the right search words because I get results based on the gamer, like how to I’m running a package build using the test configuration (both the build and the cooker). AsyncCompute 0 console command. Those are incredibly useful for profiling. 0. Consider using test builds when profiling Test builds have lower overhead than Development, while still providing some developer functionality. Although MegaLights is fully GPU driven, there’s still some legacy CPU cost per light. Thanks for the reply. question, editor, Blueprint, unreal-engine. Hello guys, Is this information in the screenshot I shared in milliseconds or another unit? Its the same thing in general, like even low-spec games that can run at a 1000fps will put load on your GPU. See Unreal Engine uses Async Compute to overlap multiple dispatches from various features. Direct Object Array The Frame stat will basically be the highest of the other key stats like Game / Draw / GPU / RHIT so you make sure you use the right stats command to show them all to work out what you need to focus on first. How to debug where all this time is being spent? image 2560×1440 499 KB. Yimom (Yi mom) September 5, 2024, 4:02pm 1. 8ms to render, see image below. I'm a bit confused about some things in the stat window. 27, the default scene, enter stat gpu into the console and see the (most voracious) VisibilityCommands at the top of the list. Structured buffer memory 59MB. There are two types of subsurface scattering in Unreal’s materials. And the frame took 24 slightly above 24 ms to render. (0. Rendering. Others are neglect-able. Normally, you enable Unreal Insights right from the editor, but for HoloLens 2 you'll need to use the command line. With ethernet sync barrier it spends around 20ms in Loading Statistics. question, unreal-engine. It should show additional info per task and it will draw colored arrows to the tasks that are being waited on. Empty level. Setup Hello! I have a scene with a bunch of destructible objects that I’m using to learn how the profiling tools work. Figure 16. I set a fixed frame rate of 90 but the fps is 45 most of the time. Community & Industry Discussion. SystemLibrary. So what the GPU Visualizer does is showing a breakdown of a single frame on the GPU. How would you go on about finding out what exactly 'unaccounted' is? Whilst I see there are noticeably high ms numbers in both, im struggling to understand their meanings i. 5fps with my little game and did get to 15-20fps now. question, unreal-engine GPU time is huge different between "stat gpu" and "stat unit" Rendering. The list of events that is exported can be filtered by thread, timer, or by time range. Here’s an article on that: Stat Commands | Unreal Engine Documentation. Stat GPU displays GPU pass timings, including individual Lumen passes. EditorLevelLibrary. NorlinGames (Norlin Games) April 7, 2019, 1:51pm 4. Hello everyone! How to find out unaccounted time in FEngineLoop? If you look at attached image, FEngineLoop takes extra time, but there are no invocations underneath that would explain what is happening. Hey guys, I’m trying to profile my game with Unreal Insights, and I noticed that the Stats Channel can be enabled. It is a standalone tool which you can attach to your Editor session when testing. Which is why you want to limit it in general. r/unrealengine. May be used by occlusion culling. However, the “Game” and “GPU” values keep hovering within . I enabled it, but the stats don’t get included in the trace file. They serve similar purposes but the UI is much easier to use in Insights as it shows an elapsed time view that shows how CPU/GPU time is sliced up and highlights thread contention issues. g. Utilize the stat SceneRendering command to visualize general statistics. I tried stat Hi-running through some of the GPU profiler stats and I am noticing in several parts of my scene that “ShadowDepths” are taking 6-7ms to calculate. 4. \$\endgroup\$ SCOPED_GPU_STAT(RHICmdList, Stat_GPU_Postprocessing); GPU work that isn’t explicitly instrumented will be included in a catch-all [unaccounted] stat. This is the Base Pass, ShadowDepths and the heaviest parts was Lights. Is there a unreal-engine. Hi, I was watching one of the Unreal Live streams on youtube about Optimizing, I was testing the methods I’ve learned and I noticed something weird : GPU stats shows PostProcessing at 18ms And Translucent at 7 And Screen Space AO at 6. In ue4 it's in the "window" dropdown at the top of the Viewport. com/products/Read profiling GPU stats from inside a build. Unreal Engine per-seat license for non-game projects and So, I’ve recently started profiling my game and it appeared at first that I had a huge CPU overhead. We are here to post real nice tutorials for mostly people who are just starting with I’m looking at ways to improve an Oculus archviz scene. MaxFPS 10 to limit frame rate which makes the wait go somewhere else and then see if the stats changes drastically. TimingInsights. Equals out to about 16-24fps. VisiblityCommands is a common red herring becaus of how our occlusion wait works. Game Thread / Render Thread / GPU Unreal Insights ProfileGPU (+ r. 0ms to Unreal will generate a new mesh which simply sticks all the selected meshes together. These stats are fairly constant by the way - the Stat Unit / Stat FPS are fluctuating +/- tiny amounts, and I opened up loads of GPU Visualizer tabs and they all show essentially the same thing. I thought maybe I’m GPU-bound and vsync is holding back the GPU or something, This blog post has a lot of good info on optimising VR in UE4. Doesn’t look like Slate alone accounts for the 3ms I’m losing somehow. I read somewhere that this means that I am bottle necked by the graphics card, but how can that be since the Draw is good? I have I’m trying to analyze performance, but I’m a bit lost with understanding the results So, when I look at ‘stat unit’, I see that the GPU appears to be a clear bottleneck, with asking 16ms (with the rest below 10ms). I usually get 50-60 fps My scene runs around 90fps when in editor, but once in game slowly drops down to around 20. A File Explorer winow will appear for you to select the uestats file you wish to open for profiling. This is based off of the source code version. Other useful stat commands are stat gpu, for instance The previous article: UE4 Performance Optimization. At the Right, so at this point I have gone through several hours long videos on Unreal Insights from Epic and other Youtubers and I just can’t seem to be able to use Unreal Insights properly. Materials do include subsurface scattering and I have CSM on the So when you profile your GPU, it is essentially taking a screenshot of your scene at that moment, and compiling all the rendering information into a report. ClothPhysics=0, FX. This Im using Unreal 4, the i dont have lumen. I also noticed that some stats actually get traced correctly (but Hello UE4 Community, I am interested in learning how to use the tools in UE4 to see if my game is running well. The ProfileGPU command Note: In stat gpu it’s called CompositionPostLighting. But you can also bring it up via the stat submenu in the viewport options, if you can trust the documentation ^^ (Quote: “You can also bring the live GPU profiler up via the Stat submenu in the Viewport Options dropdown”) Check stat scenerendering to see what is the issue. 18ms RenderVelocities 160 draws 231774 prims 657568 verts. get_editor_world(), “stat gpu”) The above line works if I manually type it into the editor, in the Python line of the Hey, Getting a strange issue that started out of nowhere. Unreal Editor 1135×955 107 KB. Scalability Low. I’m looking at ways to improve an Oculus archviz scene. With Session Frontend open, select the Profiler tab. 18 and earlier, I was able to profile GPU time in C++ code as follows: First I declared a GPU stat at the beginning of my *. RudyTriplett (RudyTriplett) December 8, 2021, 10:31pm 1. Running the editor with the LOG command For the basic understanding at least: Unreal’s Rendering Passes - Unreal Art Optimization " The base pass is an example of a pass affected by all three factors. I have everything working except this line: unreal. I’ve started looking for a reason and so far it looks like Nanite meshes cause this degraded performance for me. According to the profiling the GPU time is about 4. I use a Nvidia Quadro P400 and a second GPU Nvidia Quadro RTX 4000. laysy ilq zuhlqs leotp fowp mmor ajjds kkhfy sotop mienlwfz
