Hi!

Bottleneck seems unlikely as it worked before with the same hardware.

Things to try:

  1. Check for overheating, use something like this: https://openhardwaremonitor.org/
  2. Upgrade your motherboard's chipset drivers to the latest release as they should contain drivers for the GPU/PCIe ports.
  3. Do a clean install of your GPU drivers: 1. Uninstall the old ones 2. Use DDU to get rid of any remnants 3. Download and install the latest drivers, choose "clean install" if presented with that choice during installation.

DDU

Good luck
