Help Understanding GPU Usage Graphs in FurMark

Hey everyone! I'm running some tests on my 5700xt graphics card, but I'm seeing some weirdness in the GPU usage graph while using FurMark. The usage seems inconsistent, with periodic drops that catch my eye. The temps look okay, with the GPU hitting a max of 69°C, hot spot at 84°C, and VRAM at 96°C. Everything's running smoothly without any crashes or blue screens, so I'm not sure if this behavior indicates there's a problem with the GPU, driver, PSU, or CPU. I'd really appreciate any insights on what might be causing this issue, especially since I'm comparing it with other tests where the usage graph looks more stable. Thanks!
