Your concept of halving the framerate is wrong though… If you’re natively at 100fps, each frame takes 10ms to render. Enable frame gen and you get 10ms of additional latency (plus the latency from generating the frame itself which is often 1 or 2ms). Thats a lot less than you would claim, which would be 20+ms from feeling like 50fps.
Its more comparable to the latency from vsync if anything, which people have been using for decades even on 30fps content.
There are plenty of tests that show this online, you dont need to even napkin math it out like this.
