> mouse travels maybe 30-40ms behind my hand
That sounds awful. But it reminds me that the chart I posted is tested using a very exacting tool and even the 3090 has a 30ms latency on 120hz and that's about as good as it gets. So you shouldn't take these numbers in a vacuum but more comparatively. GFN on 120hz is better than a 3060 on native in 60hz. I know it's not compelling for anyone who hates 60hz heh but for people who are okay with 60hz then GFN latency won't feel any different to you.
