Hello everyone 

I've been tweaking p3d for the couple past days .Im Pretty much done with NVI and all these settings but i only have one question . VSYNC . Ive been trying to get it work but i cant I still get screen tearing . Is there something im doing wrong ? 

cheers

All you need to do is use an Aero Windows theme. It doesn't lock the fps to your monitors refresh rate as normal vsync does, but it removes screen tearing.

I'm confused. By Aero Windows theme do you mean not having full screen on the monitor? I have windows aero enabled but not sure what it should look like when using P3D (single bar at top of screen?)

It's not about fullscreen or not. P3D is always in windowed mode. The fullscreen option is, as I'm sure you know, just a borderless window.

When you use a windows aero desktop theme the DWM (Desktop Window Manager) uses double buffering (front & backbuffer).

The frontbuffer is what you see and everything gets rendered to the backbuffer. When all is drawn, a pageflip occurs which swaps the front and backbuffer.

This eliminates tearing as a new frame is displayed only when everything is finished rendering (no in between frames = tearing).

 

This works fine in FSX-SE too, as the DWM service is no longer disabled, as it was in the boxed version (although you can easily enable it again if you want.)

I use AutoHotKey to remove window borders and the taskbar, and everything works just like in P3D.

 

Running like this with Vsync off and unlimited framerates set in the sim unleashes your GPU.

 

It works just fine for FS9 as well.

Thanks for the info Peter. How do I know if I'm using a windows aero theme to display P3D?

Right-click on your windows desktop, then select "Personalization" from the popup, then check if your current theme is one of the Aero themes, if not select one from the list.

Playing with Aero does seem to make changes happen in some systems, but it's not vsync as you say. I've never enabled Aero but can't turn off vsync in P3D, or at least I've not been able to get tearing like with FSX vsync off in fullscreean game modes. FSX also runs with vsync on (or at least no tearing) in windowed mode which I cannot alter.

 

 

A note for those trying Unlimited. Try panning in the outside view with Unlimited fps. Panning speeds up and slows down as the complexity of the view changes and is a good example of a choppy display. I always go for fixed fps, and some stuff is improved a lot by fixed fps. Track IR becomes non-linearly responsive with Unlimited in the same way as panning, and Unlimited fps can also force some addons to work unnecessarily harder as the fps increases, if they respond on a frame by frame basis like TIR.

Excellent thank you - I'll check tonight once home.

Just to clarify, it's not a theme for displaying anything particular. It's just as hschuit wrote, just a windows desktop theme we're talking about.

 

Many prefer running vsync on and I also do that sometimes. But I like how responsive my TrackIR and also flight controls feel with it off. There is a noticeable difference without the extra 16ms lag vsync causes (in my case a 60hz monitor). Vsync On on a 120hz or 144hz monitor would be sweet I can imagine.

Replying to this thread for reference later.
