Hi Guys,

Looking for a little advice,is it best to have your frame rates to unlimited or cap them to say 30,if its better

to cap them is it best to use Nvidia Inspector or from within P3Dv4.5.

With Thanks

Gary Jones.

If you can, set to unlimited in P3D, with vsync on, with an appropriate refresh set on your TV/monitor.

Other methods involve NV inspector, or overlays, if your display can't go as low as the frequency you need.  

Mine does 25, 30, 50 or 60, so everything works well using unlimited and vsync.  Others may be able to offer you better advice on the other methods...

Hi Kevin,

Thanks for the reply, unfortunately my monitor is not capable of a refresh rate.

Thanks

Gary.

My experience is if not set, when FPS is extremely high, ground texture and autogen would not load with along the flight

It doesn't matter if it's been set by a cap or by complex add-ons, but I set it to 45FPS anyway, because some very smooth add-on like Q400 would do higher and take this effect.

 

I also tried to set limiter with Nv driver, but that doesn't works for me because it'll limit all fps from different undocked window(like PFD, ND, FMCs...)'s sum.

Your monitor most certainly has a native hardware refresh rate...most likely 50 or 60 Hz depending on where you live.  It may not have an adjustable refresh rate.

Syncing your frame rate to the hardware refresh rate of the monitor produces very smooth video...if your hardware refresh rate is 50/60 Hz, though, you'll not be able to do that unless you're running very basic acft over very basic scenery.  In that case you want to cap the frame rate so that you get fairly steady frame production, which usually means setting the frame rate such that the core running the main thread has some headroom to absorb load spikes.  That's done by flying in the most complex scenario you'd expect to fly in, and experimentally and incrementally reducing the frame rate until it holds fairly steady as you fly through terrain loads etc.

For V4 run unlimited and vsync in sim. Capping frames in sim will crush FPS, just try it you will see.  Then go to the most demanding airport you have and adjust scenery to maintain 30FPS. then you will be happy no matter where you fly.

When you upgrade to V5 you can run capped in sim.

I recommend using the Nvidia Control Panel to limit frames, if synchronizing to the screen's refresh rate isn't an option.

I have a Freesync monitor (G-sync compatible). My method is a bit strange:

1) I limit my overclock to a comfortable level that I can accept at full load, in both voltage and clock speed. I never get over 75ºC using an aftermarket air cooler. Thus, I won't have any throttling at full load.

2) I set FPS to unlimited, and I enable G-sync in NCP and V-sync in P3D directly. All because of this post:

3) Then I adjust my settings to that the worst case is never below 30 FPS (although your limit may be different). And then I use either NCP or RTSS for preventing P3D of going over 141 FPS (yes, there are some situations where this can be exceeded). Same motivation as of point 2.

Previously I got good results by locking FPS to 30 in NCP, but I wanted better. I could never stand the 30 Hz refresh rate in non-P3D operations.

Usually it's a combo of both vsyncing and setting P3D to run as unlimited, which allows maximum P3D performance while vsync both syncs and limits the frame rate.

I happen to have a 30Hz capable monitor which means my frame rate is limited to 30 FPS, most standard monitors are limited to a 50/60Hz refresh rate

Not that 50/60Hz is in itself a problem if your machine can run P3D in excess of 50/60 FPS, if it can you'd have a very smooth flying experience with a 60Hz vsync.

I run 60Hz for mormal use and have P3D auto switch to 30Hz when it starts.

There are a couple of options in the Nvidia Control Panel you can trial.

Typically there is a "Half Refresh Rate" option along with triple buffering, and half 60Hz refresh rate would give you 30 FPS.

If you're up to it there is also the NVidia Inspector which a tool providing a lot more and indepth options than the Nvidia Control Panel.

And a 30Hz vsync provides for very smooth performance, check my vids and you'll see.

For me RTSS is the only thing that works. NCP has no effect on fps or frequency and setting Vsync in the sim also does nothing. So I set Power to max. in NCP and RTSS to one half scanline sync and 30 fps. P3D is set to unlimited.

That for me is the best.

Thanks for all the advice guys much appreciated,i currently have 30FPS lock by Nvidia Inspector and set to unlimited in P3D,it seems alot more smooth.

Thanks
