Question

Screen tearing vsync issues on playback

I recently received a new Lenovo Thinkpad P1 Gen4 = intel 11950h 8 core processor, 64GB RAM, Nvidia 3080 16GB graphics card, UHD 60hz display. I have been using it for After Effects and am getting severe VSync tearing. I have tried all the solutions I can find/think of. I have tried enabling Vsync in both the Nvidia control panel (as suggested elsewhere on this forum) and in the Intel control panel for the integrated graphics. I have also tried dedicating AE to use the Nvidia card only, I have tried running both with/without hardware acceleration. I have ensured all my drivers are up to date. Nothing seems to make a difference. I'm also getting some pretty severe audio lag on playback that is inconsistent - sometimes the audio begins many frames after I begin playback. I'm not sure if the issues are related. To note, AE is certainly utilizing all of the resources as my preview renders are quite fast. There's just definitely a Vsync issue of some sort, as I see tearing during playback or simply dragging the composition window around. Any help would be greatly appreciated.

    Well, have you actually checked your cables? Also, if there is such an option, disable adaptive framerates for the display and all that stuff that's only useful for games.

      Thank you for your reply. The display is the built in laptop display, 16.0" WQUXGA (3840 x 2400) IPS, anti-glare with Dolby Vision™, HDR 400, 600 nits. I have tried nearly every relevant setting I can find in the NVidia control panel, intel control panel, dolby vision panel, and system settings. specifically, anything frame rate or VSync related, as well as all kind of power saving features in case those somehow messed with the frame rate. I've tried setting them specifically for AE as well as globally Nothing has made a difference yet. I have a test file that I made that illustrates the problem well, a simple red rectangle on a shape layer translating across the screen with motion blur, you can see the screen tearing very well on the edges of the rectangle as it moves.
