Hardware acceleration affected by motherboard?

Recently I had to replace a faulty ASUS Z490-P motherboard with a Gigabyte H510M board, having chosen the latter due to its compatibility with my existing RAM and CPU. I had a NVidia 1660Ti GPU in the original build, which I transferred to the new one. Previously rendering and playback were acceptably fast (no hesitation on playback in the editing window even with effects; fast rendering).

With the new setup rendering was hopelessly slow and I couldn't get U630 to appear in Movie Settings, only the 1660Ti. Although I tried changing the BIOS settings for the primary GPU I couldn't get the U630 graphics to show up in MEP until I removed the 1660Ti altogether. Now rendering is great, but playback in the editing window stuttery - even with frame rate and effects reduced.

Any ideas short of changing my motherboard to one more accommodating of multiple GPUs?

Thanks

Richard

@Richard-Curtis

Did you enable the Intel UHD 630 in the BIOS, Chipset, or Settings menu (?), and change the Internal Graphics option to Enabled? Following a restart of the computer both GPUs should be available.

If left on Auto then it will be disabled by the NV gpu.
