This will give you a very clear breakdown of which meshes are poly intense. ↪️Patreo I am running an Unreal Engine scene through NDisplay and while investigating the cause for very low FPS, I came across this behaviour that I've never seen before: I brought up the stats with stat unit and stat fps command So I read some similar comments about performance after porting from 5. You can also use third-party profiling tools like RenderDoc. According to the profiling the GPU time is about 4. How to use built-in profiling tool in Unreal Engine. Actually, profileGPU (aka ctrl+shift++) is the only one that is showing the correct frame times. 1. At a glance, could anyone tell I believe this is due to the AI I spawn, but I can’t narrow down exactly what the issue is as the only thing I can really find is “unaccounted gpu cost”. e (drawvisablemeshcommands, deferredshader, Fengineloop etc) and same for the GPU stats. Lumen. Just open up the mesh’s details window, and select a LOD Group. 19 ms for my Scene in GPU Visualizer but in my GPU readout for stat unit an average of 37 ms. upvotes Consol command: stat RHI. Exclusive Time is 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. Our game was programmed entirely with Unreal Engine Blueprints, we would love some feedback! youtube. Running the editor with the LOG command The Stats System collects and displays performance data to help optimize Unreal Engine projects. When I checked the processing load by Time for this graph again (How Unreal Renders a Frame). See image attached. Reply reply Top 1% Rank by size . ClothPhysics=0, FX. 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). 'STATGROUP_Game' is the group it will be displayed in (in this case "stat game"). UE4, Android, Mobile, question, unreal-engine. 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. stat unitgraph to see if gpu or cpu is bottlenecking. 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. just had the same GPU Crash issue, on a project I was working on UE 5. GPU work that isn’t explicitly instrumented will be included in a catch-all [unaccounted] stat. ini file for your scalability settings and managing the graphical fidelity. Presumably Game is I ran “stat gpu” to get some more ideas and there’s a big difference between the 2 platforms (see text file) with desktop / laptop: total: 17 / 200>370 (ms?), base pass: 5 / 45>150, unaccounted 2 / 65>224. There doesn't seem to be any real documentation on what these even are (much less profiling them properly) and other similar threads to this one have no real answers. Required by DBuffer decals. With Session Frontend open, select the Profiler tab. Testing with “new game mode” 3440x1440 resolution. 18ms RenderVelocities 160 draws 231774 prims 657568 verts. Mobile. When I use ‘stat rhi’ I see that there are many things that use the gpu memory. 23, 4. The gpu time given by stat unit differs significantly from the total value indicated by stat gpu if I set r. Now, in the upper part you have breakdown of the scene as a bar. Unreal Front End and Capturing UE stat files. but gpu time is 170ms in “stat unit” My pc setup is i7 without gpu Is there any docs about it? Thanks. In this case it was restricted to 30 fps over rdp. However, the “Game” and “GPU” values keep hovering within . It’s not running at a desirable framerate, but you’re not sure where to start. I usually get 50-60 fps You can use 'stat unit' instead of 'stat fps' to get a better view on where the bottleneck is. So, I’ve recently started profiling my game and it appeared at first that I had a huge CPU overhead. When I enter in the console “stat unit” it tells me that the frame took 18. AmbientOcclusion. Compute. the time from start of the function up until it’s return. And of course, using the editor's profilegpu feature. In ue4 it's in the "window" dropdown at the top of the Viewport. You may want to set t. Vertex buffer memory 50MB. Can someone help me out? aeonsparx (aeonsparx) August 20, 2018, 1:59am 4. question, First of all, stat unit will show you the most important list: GPU, CPU (game thread) and render thread (draw). I also checked using MSI Afterburner gpu memory use, on the laptop it was 4470GB and on laptop 3022GB (maxed at 100%). GPU showing “unaccounted” adding 3. A useful tool though is the ~ key to open the console and type Stat GPU. Smooth 1 tagged with "Whether to smooth SSAO output when TAA is disabled" and r. eg: gpu total time in “stat gpu” is 33ms. question, unreal-engine GPU time is huge different between "stat gpu" and "stat unit" Rendering. 1: 398: February 18, 2023 easiest way to log and save basic GPU stats in a file? Programming & Scripting. When I place the camera somewhere where Draw goes down, the FrameRenderFinish also goes down. The game contains max 100 players and has a really large playing area (2km x 1. anonymous_user_496097ed (anonymous_user_496097ed) May 20, 2015, 12:06pm 1. Even if the stat unit shows 22 ms on GPU, if I profile the 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). The time your GPU takes compared to the time the CPU takes to render a frame, is very long. The Unreal Directive is a passion project that aims to provide quality and reliable resources for Unreal Engine developers of all skill levels, Utilize the GPU Visualizer to quickly identify and hone in on GPU bottlenecks. Unreal engine 5. I’m currently not using Lumen, yet one of the bigger culprits is something called “LumenScreenProbeGather” in the GPU visualizer. 22 and switched to the Unreal DTrack Plugin in UE5. 8ms to render, see image below. Modified 1 year, 10 months ago. 97 using Vsync The question is, I try to display a simple background, the frame is about 15 fps, but the graphics usage is only about 20% and 10% respectively. SSGI. Hello guys, Is this information in the screenshot I shared Hello! I have a scene with a bunch of destructible objects that I’m using to learn how the profiling tools work. For the longest time I've been testing Unreal and showing how many effects rely on TAA like SSR and SSAO even tho they have commands like r. HZBOcclusion to 1. But other than that, it's creating a proper scalability. I use RenderDoc for GPU profiling Unreal Insights and stat gpu not showing any GPU data. If the directional light is stationary in the scene, then wait for problems, moving to a movable lights will remove the problem, but this does not always work. 26 and also using the water plugin, I have issues where when I place a Water Body River, My engine tanks in performance, I sucked it up and managed to see that my fps was 2 and my draw time was 300ms. Viewed 521 times 0 I need to log the basic GPU stats (computation times) in a file while testing in the unreal engine editor so that I can analize them afterwards. How can can both Game and Draw seem perfectly fine but GPU + Frame are slow and indeed my frame rate is suffering accordingly. and tried 8k 127 quads 4096 componnets A with command stat FPS iam getting 85 frames (11. The list of events that is exported can be filtered by thread, timer, or by time range. 4 and then UE5. 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. 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. At the Which variables within the Engine.
