...

Thanks for explaining!

I'm playing a game with FPS way beyond my panel's refresh rate, meaning above VRR range too.

1. If the FPS somehow falls into the VRR range and V-sync is OFF everywhere, will G-Sync still kick in?

2. I've tried once to turn G-Sync OFF manually only for that specific game's profile, and ALT+TAB was ...

Also -- "Quick Frame Transport" equivalent is already built into FreeSync/GSYNC . Variable refresh rate displays have have been doing this since 2012. Low frame rates shows large input-lag-reducing benefits on high-Hz variable refresh rate dispays, since those refresh cycles are delivered at full ...

So on a 60hz panel with Vsync, the internal/"real" FPS has to drop to 30FPS (and increase input lag)?

Yes.

Bummer. Maybe a future iteration will drop "unnecessary" frames instead.

So if you reach vsync rate, half the frames are still generated.

No matter what, half the frames are always rendered, half are always generated.

I assume the same is true with FSR FG.

Again, my question is on the technical side - what is actually happening with frame gen, vsync, limites and so on.

If you have GPU headroom sure it's a non issue might aswell use it but this assumes a few things.

At 240 FPS it becomes a non issue.

The only scenario I can think off where it's good to use is games locked to 60 FPS because you already have so much headroom on the GPU but you can't go above it ...

If you are limited to 60 HZ panel well frame gen is useless if you can already hit 60 FPS

Even if you cannot hit 60 FPS there is noway I would enable frame gen, the input latency would be atrocious and unplayable.

In general frame generation is worthless if you go below 60 FPS, it is only ...

I don't think so

If I enable frame gen on LSFG or AFMF 2 at say a game running at 100 FPS it will drop to 70 FPS

However if the game isn't demanding like Street FIghter 6 which runs at 60 FPS and I enable LSFG or AFMF 2 it will NOT drop it will run at native 60 FPS but double the frame, LSFG can ...

1. If DLSS or FSR frame gen is used, with NVCPL Vsync ON, on a 60Hz panel with real/native/internal 60FPS, since frame gen has to insert a fake frame between each real frame, does that mean that the real FPS drops to 30 - since that way you can have 1 real and 1 fake frame in a 60FPS limited/Vsync'd ...
