Sneed9 looks like a GPU bottleneck. The RTX 3080 is barely maintaining 60fps while rendering at sub 1080p resolution.
I think the graphics card's performance is being limited because it's only running at PCIe x4 speed, instead of x16 speed.
I recommend unplugging the graphic card from the PCIe slot on motherboard and then plugging it back into the top PCIe slot to make sure it has a good connection.
Please post another screenshot of HWiNFO System Summary so we can see if the graphics card is running at x16 speed.
I also recommend removing the custom user.cfg if you're using one.
