V-Sync - ‘Video’ or ‘Software’?

Hello,
As the title suggests, what is the difference?
Does ‘video’ let the display match the frames of the game, whereas ‘software’ setting respects the capped frame rate that you define on the settings page?
 
I think one is for Nvidia cards and the other for AMD cards, i have a Nvidia card so use "Video" i am sure this was how they stated it when 1st released.
 
Interesting Ian..... I have an Nvidia card and have always used 'Software', although I've no recollection now why I made that choice....
 
I’ve always read it as select video if you have it enabled in the Nvidia control panel and software if you want to use the in game vsync. Would be great to get clarification with this.

So I have gsync and vsync enabled with a frame rate cap 3fps below my refresh rate within the Nvidia control panel and have “video” selected in LMU.

This makes sense. Would be helpful if they would have a tool tip or description within some of these settings when you click on, or hover over the setting in question 🤷‍♂️
 
Just Turn it off and Limit your FPS to 3% below your Monitor HZ
3 fps lower, not 3 %
set it 3 fps below the amount of FPS you can run, not the max of your monitor
-in my case, 3 monitors are 144hz capable, but in I manage around 90-110 fps max in the game
-so my max in Windows Display (or in nvcp) is set to 100hz
-and after that an overall limit is set to 97 via the nv control panel profile, which you need to add manually

disable vsync in-game when using gsync
for using gsync in windowed/borderless manually add a profile for LMU in nv control panel - 3d settings
for gsync indeed set refresh rate 3 fps lower, by setting the max refresh rate in the nv control panel profile

I had this question some time ago. I would like a response from a trusted source, like a developer, to understand the technical aspects of it.
 
Based on all the research I have collected and come across - Video is to be used when you enable V-Sync in the NVCP. Software is to be used when V-Sync in NVCP is off.
As for the frame rate - it’s always good practice to set a few FPS below the monitor capability…more than just 3.
I am now running in Video, with V-Sync and G-Sync both on in the NVCP and the frame cap in NVCP under the LMU profile, at 115FPS.
For reference I am using a 77” 4K tv but have it configured to ultra wide with a custom resolution of 3840X1620.
This far I have been getting good result with average frames of 100-115 (under load with 10-15 cars on-screen and most graphics settings at mid or high using an RTX3060).
No artifacts, tearing, or stutter.
Anisotropic filter is at 8X, and anisotropic texture filter at 4X.
A big factor I noticed to get good frame rates in LMU, is to change post processing to low.
Mid or high bogs down the system and doesn’t seem to have any appreciable difference visually, at least as far as I can tell.

I have an i512400F with a 3060 ti. I play in 1080p on a 75Hz monitor. I have limited the FPS in the JSON to 72 and in the Nvidia panel also with Gsync activated. I feel that the game runs smoothly except in some corners where there may be a bit of slowness in the entry of frames. I think it has to do with latency. I have thought about disabling Gsync and limiting the fps to 120 in the JSON file to improve the input frame rate. At a graphic level I play with the majority in the middle and the shadows and rain in the low.
 
As I tested a few months ago, you can't limit fps in the .json file. It will be set back to a standard value as soon as you launch the game. Or did things change in the mean time? Only way I could reliably do this was via NVCP profile.

If you can, I myself have limited play in NVCP and JSON
 
So for me hasn't been running smooth since last big update, so what I found for my setup for the first time in any game had to turn on vsync in video mode all good nbow and the jaggies are less which to me is odd as its normally the other way round in most games.
 
Yes I certainly noticed a difference too after changing from “off” to “video” in the in game menu. That’s how I got to the assumption that video is if you have vsync on in NCP, but would still be good to get clarification from a dev.

Noticed a difference for the better, or worse? (with it set on ‘Video’ and Vsnyc on in NVCP)
