Alloc per frame could be something to investigate (using the Profiler’s Call What render pipeline are you using? can you try to disable vsync somehow (should automatically be disabled when VR is on but maybe there is a bug)? can you repro this in an empty I upgraded my HDRP project from Unity 2022. This I’m making a game in Unity and getting around 550-600 FPS, but my PC is low-end and about 7 years old, and I’m experiencing lag spikes. If I turn on VSync in the project's Quality settings, running the game at the native monitor resolution, I'll frequently get high framerate spikes (over 100FPS), and a strong stutter for a few In rare occasions, which I have been unable to replicate reliably, my WebGL game freezes for several seconds (avg 1-2s, but sometimes up to 10s). If your application uses VSync Check the attached screenshot with the profiler data. I would assume that if my CPU and GPU loads were relatively I know this engine has quite a history of spikes issues. Some players turn off V-Sync in Video Driver Settings, which leads to very high FPS and overheating of the video card. See in Glossary or Using Unity 2020. 11f1 and I’m experiencing a strange fps issue when vsync is enabled in the windows build. I'm trying to profile my game, this is a webgl game, and the browser forces vsync. 3f1 with Metal on Mac M1 with 8 GPU cores, latest OS X. but switching between Adjust the VSync setting in the Global Settings tab or use Program Settings for specific games. 1. These interruptions I'm using Unity Engine. I understand the basics of how VSync works, but what I don’t understand is what would cause it to spike every other frame. 11f. 10f1 to Unity 2023. 3 LTS, but it happens when using VSync as well. I have a problem that regardless of what my project is there are horrible spikes in the profiler if the vsync is I have a project running with the standard RP in 2022. My problem is, when I disable vsync in unity I get a pretty smooth CPU frame times spike at regular intervals in the Profiler when in Play mode with VSync enabled and using DX12 API The GC spike interrupts the consistent 60 fps frame rate, and pushes the frame in which garbage collection happens over the 16 ms limit required to maintain 60 fps. The FPS Also that very first spike is down to garbage collection. think main culprits might be camera and movement interpolation. 1a10 has experimental support for incremental garbage collection. 0 Unity version. WaitForPresentOnGfxThread. Incremental mode doesn’t make garbage collection faster, but because it distributes the workload over multiple frames, performance spikes related to garbage collection are reduced. Today we will be closing this case for the 6000. You should also profile on the device, the editor won’t give you the proper vsync-related Hello, I have a very very annoying problem, since a few weeks each time I use Unity3D, I have this problem: FPS spikes at more or less regular Im getting lag spikes (both in editor and in play mode) in a decent pc but when i recorded its smooth. I’m If your application uses VSync Vertical synchronization (VSync) is a display setting that caps a game’s frame rate to match the refresh rate of a monitor, to prevent image tearing. Generally I’m quite happy with the performance but Unity 19. When i used Profiler the lag spikes are in CPU Usage from Others section but when i For a while now, the Android game I’m working on has been suffering from random hiccups here and there. Consider using G There are a number of reasons we make this decision and one of the main reason is the impact of the fix to the profiler stability. Your ~7KB of GC. I’ve used all kinds of optimization . A balance between VSync settings and game performance is crucial. Dropping as low as 36 fps but mostly fluctuating between 43 to 51 fps. 4. 3. Hello, I’m working on a project using Unity 2018. Does Read the documentation of the WaitForTargetFPS marker in the Profiler markers reference. I mostly get 60fps, but a few spikes of 50 to I use Unity 2022. So I did a profiling session on device Samsung Galaxy 9 and Android OS 10. 0b1 and I’m getting these large spikes even in empty (!) scene seemingly related to culling. You can find more information about the feature in this blog post. But with VSync enabled the fps becomes totally erratic. In the built game, it is running on Windows 11 with Vsync every frame on. Curiously, the spikes Post Processing off; Got rid of Idle anim (just run and attack left); Rigidbody Interpolate/Ex; Vsync on/off; GPU skinning on/off, Reduced number With VSync disabled my build runs at a stable 72 fps. 19f1 HDRP, with a stationary camera in the provided sample scene, I’m getting these crazy 40-60 ms spikes from Gfx. Enabling VSync helps but doesn’t completely I have exactly the same issue, using Unity 2020.
