The video card is not working properly during gameplay.
discovered a large empty space where I could be achieving around 60 frames per second by spinning a lot (just for comparison)
I don't believe the PSU is the issue since it should back that hardware (though the 2070 suggests a 550w). Maybe wait for more driver or game updates (currently at 1600x900btw). If overclocking removed the GPU clock problems, that could help. If not, I'd request an RMA—unless someone smarter here can assist. There are plenty of knowledgeable people here.
Increase your screen resolution to the next step up (ex. 1080p to 1440p) and see what that does. If there is no difference in frames it would be a CPU bottleneck (likely a bug in a new EA game, that CPU is plenty fast) if you take a big performance hit that means your GPU isn't working properly (potentially fixed in a driver update).
I actually performed that test. I noticed possibly a 1-5 fps variation, which suggests a CPU issue with the engine?
