8k output with Decklink 8K PRO card
Hi,
I have a problem with making output 7680x4320 60fps with Decklink 8K PRO card.
Preview has a many frizzes , but fps counter shows 60 FPS. If I reduce the frame rate to 30, the output looks normal.
The load of the video card and processor is not higher than 60-70%.
What could be the problem?

Hello @fariddinsharapov,
The processor is not a good metric, as the bottleneck is probably the amount of data travelling on your motherboard.
What is your machine ? MacPro 2019 ?
Are you sure your card is connected to the right PCIe (it requires a PCI Express 8 lane generation 3) ?
Are you sure you correctly setup your machine with "Expansion Slot Utility", see this article ?
Best. Philippe
