240hz is not bad choice for video playback as it divides evenly with all the commonly used frame rates including after adding in interpolated frames in most cases. Just not 72fps.

Personally I don't use 72fps at 240hz as it doesn't fit evenly. Needs frame blending, pulldown or VRR etc to be used. x3 is generally considered most optimal overall but not if it also requires the use of frame blending, pulldown etc. Which is more of an issue for 60hz monitors.

I would aim for either 48, 60, 120 or 240 after interpolation unless you have VRR working with video playback.

I think 120fps(or 240fps) would be the best all round target to avoid both pulldown and still maintain peak perceived smoothness on a 240hz monitor.

What settings are you using for svp? I decided to use 144hz mode on my monitor because there are just so many artifacts when interpolating up to 240fps

Yeah diminishing returns for sure, I find after about a ~x3 increase or ~72-90FPS any smoothness gains start to drop off fast. Your current monitor can already hit a x4 - x5 fps increase in most cases so your covered.

Films also have naturally occurring motion blur from the camera shutter speed which can vary from film to film, which gives additional smoothness not found in games(unless added in). Saving Private Ryan for example used 1/198 rather than the standard 1/48 shutter speed.

So a extra + x1 FPS increase(x3 -> x4 - x5) may help the smoothness in that case due to the loss of motion blur but ultimately not really needed. Games also benefit from reduced input delay, which is not relevant for video playback. So for games the extra is far more noticeable.

In saying that I do have a 240hz monitor which I've tried with SVP @240FPS. The main thing I noticed if anything in regards to video playback was that camera panning/motion was more clear(not really that much smoother) at 240hz/fps.

When it comes to motion clarity it mostly comes down to how long a pixel is continuously visible for and that the response times are fast enough to keep up with the refresh rate on sample-and-hold displays.

Running at 240-FPS did use a bit more system resources but I found it wasn't an issue at all for me, so I just left it at 240-FPS.

I just got the acer xb27 240hz, and you’re right it’s really not much smoother overall even though panning and movements feel clearer but slower at the same time. I have to tune down my mpv shader settings though because my gpu usage is double.

I’m currently using 144hz monitor and planning to upgrade to 240hz monitor but I’m still kinda hestitated because 240fps will tax my system a bit more than 144fps. Does anyone have experience with interpolate to 240fps and is it smoother than 144fps?

I think it is because the laptop panel is connected directly to the integrated gpu, even though the Nvidia gpu is decoding it, the video still has to be sent back to the iGPU to display the video and most of the time iGPU is not strong enough to display it. If your laptop has a mux swith, you can disable optimus so the laptop will only use the dedicated gpu

Hi setsuna, thanks for the hint, I think this should be the cause. However even when I force the player to use the nvidia dGPU it does not change anything. I think it always get back to the intel GPU to display the frames

Hi Chainik, here are some logs, I don't know if this is enough/useful.
Thanks

This is not something you can swith with software because the screen is physically connected to the iGPU. You need to check if your laptop has a mux switch or not. Usually there is an option in the bios to disable hybrid display/optimus. If your laptop doesn’t have one, the only choice is to use the external monitor through hdmi or display port because these ports are connected directly to the nvidia gpu

Hi everyone, I'm planning to buy a HTPC for watching 1080p 120hz movie and I'm stuck between these two specs:
i5-9400f, GTX 1660ti
Ryzen 5 3500, GTX 1650 Super
Which one do you guys think is better for my use case? If I use NVOF, is there any difference in performance between GTX 1660ti and 1650 super?
Thank you
