Please can someone answer why this is happening?
I have an Alienware AW3423DW which has a built in G Sync module and using an RTX 3070.
When the in game V Sync is off I get stutters. But as soon as I turn it on the stutters are gone.
I thought that I didn’t need to turn on the in-game V Sync as I already have a module built into my monitor. Am I right in thinking this or am I wrong? Do monitors with built in G Sync actually do anything in FS2020?
What’s “in-game G-sync”?
I was on a campsite many years ago. I decided to have a shower, but the queue for the showers was long. Except for one shower.
Nobody was waiting for that one. I asked why. Because it only had cold water. I was told.
I had a look in: hot and cold supply pipes. So I tried it. The water was freezing. The temperature knob was all the way to Hot. So I moved to the middle. Result, a warm shower.
The only thing wrong with the shower was that the temperature control label was the wrong way round.
Why is this relevant? Well, if ‘V Sync on’ works for you, where’s the problem?
I meant in game V-Sync, post edited.
There’s no problem I just want to understand why this is happening. My monitor has a built in G Sync module which I presumed did all the work so no need for the in game V Sync. I don’t think your analogy is the same here in this case.
There has been a lot of confusion regarding G-sync and Vsync. Monitors display whatever the GPU sends. If the monitor’s refresh rate is different than what the GPU is sending, a monitor might display a graphics frame and then part of the next frame within the same refresh. If there is motion between the two frames, tearing would be visible making the graphics smeared or blurred.
G-sync is a hardware solution to fix tearing. For G-sync to work properly, it needs specific hardware in the monitor and NVIDIA GPU and enabled in NVCP. G-sync changes the monitor’s refresh rate to match the frame rate sent by the GPU eliminating the tearing.
Not everyone has a G-sync compatible monitor or a NVIDIA GPU. V-sync is a software only synchronization modifying the frame rate of the GPU to display frame properly (synchronized) on the monitor.
Vsync can be adjusted in MSFS since it is software-only. G-sync cannot be adjusted in MSFS because it is NVIDIA hardware-only.
I personally leave G-sync on all the time and don’t use Vsync. Others use both or only Vsync. Use whatever works best for you.
There should indeed be no stutters caused by having G-sync enabled (assuming it is indeed enabled and functioning correctly) with V-sync off.
What V-sync could do, though, is introduce artificial delays between frames which might even out an existing inconsistency in frame timings due to something else. You might double-check the developer mode FPS meter to see if frame times are going wildly up and down for some reason.
G Sync and V Sync are not equivalents.
My analogy was about choosing what works best, no matter what others say. I’m sorry I failed to explain it clearly enough.
