What is my bottleneck...
I also have an MSI Z270 GAMING M3

It seems the issue might be related to the game itself—lower FPS is acceptable. The monitor I use matches the one described, though a newer model is available. What caught my attention was that V-Sync didn’t affect FPS, and G-SYNC appears to activate it automatically. That could explain the behavior.
Not true. I gamed on a Pentium G3258 + GTX 970 combo for a week or so waiting for my real cpu to come in, and I would be hugely cpu bottlenecked many times without hitting anywhere near 100% cpu load as shown by the RTSS overlay. Or maybe the RTSS was measuring wrong. But it showing 50% cpu load doesn't mean you're not being bottlenecked, because it did it for me on that cpu.
I was observing the performance data as shown by RTSS through MSI Afterburner. When I replaced the Pentium G3258 with a Xeon E3-1231v3, my GPU utilization reached a constant 99% across all games with VSync disabled (perhaps for some reason RTSS never displayed full usage).
The VRM is probably fine since it won't see anything with more than 4 cores, but the VRMs heat sinks just look like big chunks of metal (no fins... fins = good). Just make sure there is at least a little airflow over the heat sinks for long term use (doesn't have to be much).
V-Sync framecaps at 60 fps. G-Sync and Freesync do not cap framerate. It's weird there is no difference unless you get ~60fps cap naturally (without v-sync). Do you get over 60 fps with v-sync?
I thought V-Sync only restricted the refresh rate of my monitor. For example, it capped it at 90 Hz since I pushed it from 60 to 90.
It would be interesting to check the game with GPU-z in the Sensors tab to see what "PerfCap Reason" tends to be most often. It might usually show as "Util," though I want to confirm. Perhaps the issue is that the game is becoming too large for its own sake.
