1.3.0 / Unity issue with Gear VR: Motion blur & juddering
Hi,
When moving my head around, there is a judder issue (like a double texture rendering halo for a few ms), it's very visible with a B&W texture with only lines.
- I tried other games on the oculus store with this gear VR and it's working well
- When my app is starting, there is like 1/2 second without this problem, then a 'visual glitch', like if the system is re-adjusting the rendering, then this problem
- I displayed the FPS on my app and it's between 50fps to 60fps
- I have this issue even when I close one of my eye in the gear VR (it's not a stereoscopic vision issue)
I cannot record it but this screenshot on geekzone (it's a different issue) is very similar to my rendering in VR (only when moving my head): http://www.geekzone.co.nz/imagessubs/blogfdbb14e244726b80556df55a0b54b5e8.jpg
Any idea how to solve this issue ?
I'm using a Samsung Gear VR / Galaxy S7 edge, Oculus 1.3.0 and Unity 5.3.4p2 (I tried with p1 same issue)

- Can you share logcat from a run with this issue please? It sounds like you may have used the OVRPlugin that was built into Unity instead of installing the new one (1.3.0). OVRPlugin is different from the Utilities, which it sounds like you already have. See https://developer.oculus.com/downloads/game-engines/1.3.0/OVRPlugin_for_Unity_5/
- Hi,
Thank you for the reply,
I re-installed the plugin to be sure, I still have the same issue.
I'm using the gear VR developer mode to get adb working with Mac (so I'm not plug on the GearVR but on my computer). I have a small adb log using the "adb logcat -s Unity dalvikvm DEBUG", if you need more, adb can be very verbose, I'll put this in a file.04-10 19:36:36.415 21658 21679 D Unity : GL_OES_EGL_image GL_OES_EGL_image_external GL_OES_EGL_sync GL_OES_vertex_half_float GL_OES_framebuffer_object GL_OES_rgb8_rgba8 GL_OES_compressed_ETC1_RGB8_texture GL_AMD_compressed_ATC_texture GL_KHR_texture_compression_astc_ldr GL_KHR_texture_compression_astc_hdr GL_OES_texture_compression_astc GL_OES_texture_npot GL_EXT_texture_filter_anisotropic GL_EXT_texture_format_BGRA8888 GL_OES_texture_3D GL_EXT_color_buffer_float GL_EXT_color_buffer_half_float GL_QCOM_alpha_test GL_OES_depth24 GL_OES_packed_depth_stencil GL_OES_depth_texture GL_OES_depth_texture_cube_map GL_EXT_sRGB GL_OES_texture_float GL_OES_texture_float_linear GL_OES_texture_half_float GL_OES_texture_half_float_linear GL_EXT_texture_type_2_10_10_10_REV GL_EXT_texture_sRGB_decode GL_OES_element_index_uint GL_EXT_copy_image GL_EXT_geometry_shader GL_EXT_tessellation_shader GL_OES_texture_stencil8 GL_EXT_shader_io_blocks GL_OES_shader_image_atomic GL_OES_sample_variables GL_EXT_texture_border_clamp GL_EXT_multisampled_render_to_texture GL_OES_sha

Gui. - Hi,
I found a solution/workaround: I used all settings asset from the unity sample project (I just copy and paste everything on the project settings unity folder) and it's working. I'm not sure what was this issue (probably my quality settings) but it solved my problem and now the rendering is very nice !
Thank you for your help !
Gui. - Hi Riviereg,I'm experiencing the same issue...FPS are 70 or better, still there is this 'judder'-effect present all the time - except for the first couple seconds of runtime...Not quite sure which Unity-sample-project you are referring to? Could you help me out here?Thank you in advance + best regards
- Hi SamJan,
I was using the Oculus Sample Framework project settings (https://developer.oculus.com/downloads/game-engines/1.3.0/Oculus_Sample_Framework_for_Unity_5_Project/) and faced this issue. I did reset my project settings in Unity with a "default settings" folder and it solved my issue.
I can share with you my project settings or help you directly (for PM chat, my user @gmail.com for hangout) if you want.
Gui. Hi Gui,
thank you very much for your offer. I'll try to replace my project-settings-folder as suggested.
Strangely enough this issue is occuring with both newly-created and pre-existent projects alike, so I don't expect this procedure to act as a remedy in my case... Well, fingers crossed! ;-)
Thank you again + best regards
- @SamJan, judder is typically due to poor performance or exceptions. Can you provide the full logcat from your app, from the time it starts to the time you see the judder? It may help to attach the profiler and look at where the time is going.
