A quick question about adaptive Vsync

Recommended Posts

So, I just realized that 1/2 refresh doesn't work in P3Dv2 due to the fact the sim does not run in fullscreen but there's a thing called Adaptive vsync. My question is does this only work with frames set to unlimited? Can I lock the frames? Most of the time my frames are pretty high but in some areas or with some airplanes they fluctuate a lot which produces stutters. Maybe locking the frames would help (like in FSX) but would Adaptive Sync still work?

As you can see I have no idea what Adaptive Sync actually does.. is it something similar to 1/2 refresh rate which I used in FSX and made a huge difference in smoothness? What's the word on P3Dv2 fullscreen.. are they working on it or is it impossible or something?

Because P3D runs windowed mode, you only need vsync with fps set to unlimited. This way you prevent tearing when game fps exceeds your desktop refresh rate (which usually is 60Hz).

 

If you set P3D fps limit lower than your desktop refresh rate, you don't need vsync.

 

Standard vsync may induce stutter because it throttles down in steps from 60 > 30 >20 >15 fps when game fps drops below desktop refresh rate.

Adaptive vsync helps to prevent this stutter because it switches vsync off when game fps drops below desktop refresh rate.

But is there any connection between 1/2 refreh rate and Adaptive vsync?

What's generaly better.. frames locked at 30 or Adaptive vsync and frames to unlimited?

I prefer fps locked at 30 and vsync/triple buffering disabled (btw, you must use an Aero desktop theme).

But if you want unlimited, then adaptive vsync is your best option.

And: Forget about 1/2 refresh rate, that only works in full screen exclusive mode (FSX).

Hi

I have my frames set to unlimited, vsync and triple buffering are on in p3d settings. That's all. Although I've never used Adaptive vsync. I'll try it, and let you guys know what I think  :) 

Cheers

BTW, did LM tell why they took out Full screen exclusive mode?

One of the reasons, Artur was that so many people wanted to have other programs running on a second monitor and that was impossible with true full screen.

 

Frankly, I prefer the windowed full screen - I see no real difference and I have the second monitor available.

Ok but why than not both options?

1/2 refresh rate doesn't work in fake full screen and this made a huge difference in smoothness in FSX, I suspect P3D would benefit from this one also. P3D is performing OK for me apart from microstutters.. which would be eliminated with 1/2 refresh rate sync option (like in FSX). That's why a lot of people would like to see true full screen.

Windowed mode is already present in P3D.

Just as they created the program, there are two (one mistakenly called "Full screen").

I would love to have the ability to run in true full screen and use the same method that produces such a smooth experience in FSX DX10.

 

This is the one reason I am not spending too much time in P3D right now which is a shame :(

Exactly! This is not some obscure function a couple of people want.. it's a major feature that would make P3D experience so much better for a lot of people.

They also stated that there were significant bugs in the code for "real" fullscreen. They did not identify those bugs.

FSX must also have those bugs than... and I was happily using it for years in fullscreen. Even if there are major bugs, LM has the code and they have a great opportunity to solve those bugs. As I said in the other forum.. it would be great if there'd be options. I don't know why some people are so against that.

Also P3D 1.4, the SIM more stable and smooth that I've ever had (unfortunately without ASN).

Prepar3d like FSX 1.4 uses DirectX 9.0c. Prepar3D 2.n uses DirectX 11. They are differebnt.

 

“And to also add, in practice, using FSX with multi monitors will black out all but the main monitor.”

“Both NVidia and AMD have their own special driver features that are not part of the D3D11 standard.”

You mean it will black out in fullscreen, not windowed or windowed borderless, right?

Yes.

The Desktop Window Manager (DWM) in Vista and later changed the way applications display pixels on the screen. Individual windows no longer draw directly to the screen or primary display device. Instead, their drawing is redirected to off-screen surfaces in video memory, which are then rendered into a desktop image and presented on the display. When in fullscreen mode DWM is disabled.

I think people need to try setting their frame lock to something other than unlimited in sim and see how much better P3D handles locked frames than FSX does.

 

I was a die-hard FSX Fullscreen, Unlimited Frames with 1/2 Vsync user up until switching to P3D, but I now use frames locked at 32, even in dense areas where I used to switch to unlimited in FSX to try and keep the FPS higher.

 

Try loading up a dense scenery area, enable a framerate counter (either internal or external), then try changing the frame rate lock from 20, 30, 40, 50, 60, etc. until you find where it stops going higher. Once you've figured that magical number out, switch to unlimited and I bet you'll see the exact same value...

I use TrackIr and there is a big difference between unlimited and locked. Without TrackIr locked looks pretty good but even with locked there are still microstutters that would be eliminated with 1/2 vsync.

Believe me I have tried everything to get a smooth result with frames locked, it just doesn't work on my system which is not exactly a slow PC ! FSX DX10 is black and white different. I have invested in P3D & the NGX but this will keep me away for a while.

 

I have just brought X-Plane on Steam along with the FF 757. Yes X-Plane has some quirks, Yes I have downloaded alternative mesh but I have to say I am blown away by the scenery and the fluid flight. Tons of free stuff including an awesome plugin that allows me to have all the flight displays running on a networked PC. The quality of addon aircraft is also getting much better. Hopefully PMDG will port their existing aircraft and I am keeping my fingers crossed that the 747 V2 will also be available.

 

I will still visit P3D from time to time but right now I am spending more time in 'The Other One" !!

I won't go into this sim is better than the other sim because... I'll just give a simple reason why I'm not switching. Addons. I spent A LOT of money on FSX addons (a lot of them I'm now using in P3D) so it will have to be something much much better than XP10 that will make me switch.
