Variable refresh rate is best on monitors that have high refresh rates because there’s a wider range of fps that it can adapt to. Even if you’re only at 80-100 fps, you’re benefiting from your refresh rate of your monitor being higher, particularly for frame times.

Also, I simply cannot imagine why you’re offended about refresh rate reaching 120hz. That’s purely a benefit. You can turn it down to save battery. There is literally zero downside.
