How does Furmark read GPU index?

Hi,

May I ask how Furmark gets the order of GPU in its startup interface? I currently have a GT1030 sits in slot1 and an RTX 2080TI in slot2. Interestingly, when I boot in legacy mode, I got GT1030 listed above the RTX in Furmark (as expected). However, when I boot in UEFI mode, now Furmark considers the RTX as the first GPU and the GT as the second. Any idea what happened here?

FurMark uses NVIDIA drivers to enumerate GeForce graphics cards. Then, the order of GPUs is controlled by NVIDIA, not by FurMark.
