Question GPU drawing only half of TDP at 100% utilisation.

[late4CCourt]

I recently completed a build with a XFX Speedster SWFT 319 Radeon RX 6800 16 GB, which has a TDP of 250w, yet wont draw more than 135w, even at 100% util. I have stress tested in both Adrenaline and Furmark. My PSU is rated for 750w, so I should have more than enough power, and my GPU is connected to my PSU using 2 separate PCIE cables. I am getting markedly poorer performance in games than I should be with my specs as a result I am using the latest version of windows with the latest drivers for my card. Any ideas on what might be causing this?

Check with GPU-Z PCIe speed and number of lanes.
