Ahh that classic "I dont have a time" excuse. In order to defend your own opinion, you had to ask the AI for help.
I remember testing DLSS3 and anything above 40fps worked perfectly smooth, while framerate below 40fps caused long stutters. However, Nvidia has improved frame generation with DLSS 4, which now calculates everything using Tensor cores. With DLSS 4 FG, it was no longer necessary to disable VSync, and drops below 40 fps no longer caused stuttering.
Here are the latency measurements in Cyberpunk. I forced VSync in NVCP because for some strange reason, it improves the experience with DLSS4 FG instead of ruining it, as was the case with DLSS3 FG. I also capped framerate with RTSS and "reflex" framelimiter mode instead of default "async" (async adds 100ms lag and makes FG games unplayable). Look for the Nvidia OSD in the top-right corner.
Real 60fps - 29.8ms latency
Real 30fps - 43.1ms latency
DLSS FG 60fps (30fps input framerate) - 45.5ms latency
There's only a 2ms difference between 30fps and generated 60fps. If someone doesn't believe my measurements in Cyberpunk, I recommend watching this video. It's timestamped. This YouTuber was surprised to learn that DLSS FG didn't increase input latency.
A 2 ms latency difference is in the realm of placebo, while 2x higher framerate drastically improve perceived smoothness and clarity of motion. Generated 60fps also eliminate the 30fps judder, so you dont even need to use ingame motion blur filter to hide it. I tried playing Cyberpunk at 60 fps for a few minutes and it was definitely a much better experience than playing the game at 30 fps. Even though latency didn't change that much, it was much easier for my eyes to track moving objects and my aim was also more accurate (much closer to real 60fps than 30fps). I think many console games would be convinced that they are playing at a real 60 fps.
Personally I usally use FG to play with 70fps and that gives me around 120fps generated, but this technology is definitely usable at lower framerate as well. I even played Black Myth Wukong and Alan Wake 2 with Path Tracing at generated 80-100fps and my experience was amazing.
