I strongly agree with the comment about DLS 3.0.
They're not real frames, and they introduce a delay. It adds half a frame of lag to delay the last frame and add in that interpolated frame in between.
A lot of players with lower end GPU play at relatively low, or very low, framerates.
For someone with a 4080 playing at 120 fps, half a frame delay is not a big deal. It's 1/240th of a second. But for someone with a low-end GPU playing at 30 fps or below, it is a big deal. It is extra lag you simply don't really want if your FPS is already low.
The lower your framerates, the more milliseconds of lag DLSS 3.0 introduces. When a game temporarily drops to 10 fps, and you delay that latest frame even more, that just tanks response time. It's like putting the chains on an already struggling GPU.
At 30 fps DLSS 3.0 adds 1/60th of an input delay. At a struggling 10 fps DLSS 3.0 adds 1/20th of a second of delay, that's an extra 50 milliseconds of lag, and you're definitely going to notice that, stutters in games will seem much worse.
I truly hope Nvidia is not going to pull out the "DLSS 3.0" fanfare if they make a desktop 4050 or 4060, because that extra bit of lag DLSS 3.0 introduces is negligeable at 120fps, but is a problem at 30fps and below.
