Same on Gigabyte 2070 Super Windforce 3X OC.

I found that doing the following helped:

- Adding an exclusion in my AV (Bitdefender) helped
- Set process priority to high
- Run fullscreen
- Enable Fast sync within Nvidia Control Panel
- Disable V Sync in game but leave the Nvidia setting

FPS, whilst still unstable, went to 60-75 but at least the 1-2s lock ups disappeared.

Game is still very much EA performance wise.
