[DX11] Help regarding Nvidia Profile Inspector (NPI)

[Sansemiano]

Yes, that is my experience too. Limiting the FPS of the monitor itself gives undesirable side-effects in an adaptive sync setup. It's best imho to let the monitor run on it's max speed and let freesync or gsync do it's job. The system will adapt then the fps automatically to the load depending on how much graphical goodies are switched on.

However limiting the framerate to 60 fps with RivaTuner (or other way) in an adaptive sync setup has no use imho. Just let the system do it's thing.

@theclumsygeek

So, you are actually using several layers of syncing and limiting FPS.
Then it's not at all strange that your system gets confused! Just joking!
Well, I have eliminated all my previous similar stuff and now I have ONLY
a V-Sync type, for 1/2 the refresh rate. One single sync/limiting setting!

@Sansemiano

Well, one problem with that solution is that the GPU/CPU load is NOT
controllable. Those loads will be what they will be!

[Sansemiano]

@BenganJ: Yes, but as long as the monitor adapts to the delivered framerate what's the problem with that? As long as the system runs in it's adaptive sync range of course. In my case it would mean to tune the graphic goodies so that the framerate stays above 50 FPS. The range is 50-144.

@Sansemiano

It's no problem at all, your GPU/CPU spewing out frames en mass without any need for them at all!
Just kidding, but it's to some extent true mate, why create an overflow of frames not needed?

@Bengan haha yes, apparently I'm not the only one confused, my pc, too.

@Sansemiano rtss fps limiting works quite well. It gives very consistent frame time with minimal input lag (negligible in non-competitive gaming). But you're right. In a normal scenario, I wouldn't try limiting fps. I just have a special requirement of recording / streaming content where 60 fps is optimal. Experience has taught me that having inconsistent fps (even if it's higher than 60) causes more video stuttering in the recording. So my option is either constant 120 fps (which my GPU can't handle), or limit to 60.

@theclumsygeek & @Sansemiano

I know you both are on the G-Sync side and I'm not. My three Samsung monitors are all with freesync,
BUT NOT G-Sync compatible, so a no-no for me. It's a pity Road Runner disappeared from here, more
or less, he knew a lot about that!

That is a good question. I think we now get into the discussion about high fps or not. I think 100 fps is preferrable above 60 fps. And 60 fps way more preferrable above 30 fps. When driving along the freeway with 50 mph the signages along the road stay much longer readable with higher fps. Same counts for panning the camera.

We get a bit into the field of what you like most and what you think is preferrable.

In the end every system has it's limits of course.

Ok, I will experiment a bit with RivaTuner FPS-limit. Always interesting.

Maybe a tip for you: I record my gameplays too and upload them to YT. Not thousands of viewers like you. Just me and a few other people. ;-)

Anyway: despite the highly variable framerates I see no stuttering in the YT-movie in the end. I record with nVidia Shadowplay @ 20 Mbit. I think that's done with hardware in the GPU. I notice no influence of the record-process on game fps.

I think you record with OBS? Guess you need that for getting an image of yourself in the stream-play. I'm not sure if that is possible with nVidia Shadowplay. OBS is a huge load on the CPU during recording.

@theclumsygeek & @Sansemiano

Talking about RivaTuner, has any of you tested Scanline Sync? I can't get that one properly working!

[Sansemiano]

Nope, haven't tested that. Did some Google-searching and it is an alternative to freesync/gsync? This url gives an overview. Sounds pretty complicated:
