I don’t know why you’re getting downvoted. We all joke about 1khz being unacceptably stuttery for esports but… we’re well on our way to doing that on the high end. Frankly given the CPU bottleneck on a 4090/7900XTX at 1080p we might actually already be there with GPUs, or we’re very close.

A kHz refresh 1080p display will be very usable with adaptive refresh already, honestly.
