When I use with capture card with high resolution or frame rate but the preview and recording file doesnt perform properly, how to fix it?

Our device GC573 need to be installed at least on a PCIe 2.0 X4 bandwidth. Ideally, to read and write the data utilization, the MPS (maximum payload size) need to be set at 256 bytes. You can refer to the data in the HWinfo (Tutorial link) . Please check the PCIe dispatch for your board and there is another PCIe device that restricts the MPS when sharing the PCIe bus with the capture device if you found the MPS at 128 bytes in HWinfo or the result of the Performance test didn’t reach the 4K(HDR) resolution recording.

 

In addition, you may check your motherboard PCIe allocation on user manual. On some motherboards however the PCI-Ex16 slot is set to x2 mode by default.

Make sure to check your motherboard’s BIOS manual and confirm the necessary steps to adjust the bandwidth of the PCI-E slot accordingly (to X4) so as it can match GC573’s requirements.
