Jerky Playback with GT 1030



Sorry for the multiple posts but I’m not having a lot of success with my graphics card or searches.

I have a ‘new’ NVIDIA GeForce GT 1030 in my Win10 HTCP, with both Win10 desktop and Kodi resolutions set to 3840 x 2160.  All drivers installed and screen calibrations are good.

Having said that, NextPVR and Hauppauge WinTV-HVR-1265 are not happy – OTA channels are very jerky, some worse than others.  Streaming video and ripped content are fine.

Is there a setting I’m missing?  I didn’t pay much for the NVIDIA, plus I’m not finding a lot of 4K streaming content for this platform, so I can live with reverting to the onboard GPU (just HD) if that’s the answer.

Thanks in advance.
