Skyrim Vsync question

[Grospolina]

EDIT: I can confirm the Vsync is working perfectly reducing the screen tear and capping it at 60 FPS, yet my framerate never jumps from 60 to 30 and then to 20. If someone with a little more insight as to why my FPS isn't 'jumping' can help, I'd be grateful. Just some extra knowledge would be nice to have.

Essentially, what is happening is that the frame rate is changing faster than your FPS meter is measuring.

 

In order to measure FPS (frames per second), you count the number of frames over a certain time period. This might be one second, a half second, a quarter second, or something else. Every time it's measured, the FPS display is updated. So, if you make this period too short (say, every 0.05s), then it will update much too fast and you'll just see an unreadable blur of numbers.

 

Let's say it actually updates every second. Your frame rate may jump between 60 and 30 multiple times during this period. If it went perfectly evenly like 60-30-60-30-60, this would give you 45 FPS. However, realistically it would be more random since it depends on how hard the graphics card is working at any given time. It might be something like 60-60-30-60-30-60-60-60, etc. and this would give you something in between, like 53 FPS.

 

You can think of this as being an "average". Technically though, the number of frames that you see in one second is quite literally your FPS.

Very interesting. But i got a new aspect regarding the ongoing v-sync discussion.

 

What about g-sync?

 

I got a AOC display using g-sync and a refresh rate of 165 mhz. And i still don't know which setting i should use. Right now i'm doing a perfect "try and error" run....

 

Generally speaking: even with g-sync on, am i supposed to turn on v-sync? Which Setting is recommended?

 

My System: Geforce GTX 980ti, i7 4970k, 16gb ram, win 10 pro 64bit, Samsung 850pro ssd, aoc ag271qg

you can leave v-sync off in Skyrim just use a tool like nvidia inspector to lock the frames at 60; and g-sync on frame rates under 75 doesn't really work well.

G-sync doesn't work well under 75 fps? Hmmmmm.. Gotta check this out first.

Thinking about what've read so far there was no negative side effect using g-sync. Besides the high prices for that type of display......

 

For me it comes to one simple question: why should i limit my frames to 60 when i got a solution that prevents tearing (or any other negative aspect of using a higher frame rate)?

G-sync was supposed to solve this issue. At least i expected a big step forward using a display with g-sync.

I was just saying that on Skyrim it doesn't make too much of a difference because the game cannot go over 60fps and the g-sync monitors deliver the best performance (less input lag and best sync) while over 75fps or at least on 144Hz monitors (this has been tested on the same model of my monitor ASUS ROG Swift PG279Q so i cannot confirm it for every g-sync monitor); If you don't lock your frames at 60 in Skyrim the physics becomes crazy and just touching and item makes it fly at extreme speeds and some times just opening a door can kill you in game if you have more then 60 frames.

[Rubberduck69]

Sounds reasonable. But i never had these physics issues. At least until now.

 

Gonna check this out again!
