P3Dv4.5 frames

[Pitter 23]

After a long time of try and error I finally found an acceptable setting (FPS) in P3Dv4.5.
The only thing I can't get a handle on is the fluctuation of frames, in the range of 18 up to 35.
Can someone give me a tip please?

Thks, Peter

How are you locking your frame rate?

In sim or externally?

My experience has been that fluctuating frames were due to specific addons, mainly aircraft with complex systems.

Try locking externally at 30 and unlimited in sim.

As Rogen asked, what are your specs?

Sorry for late answer.

Hey @Pitter,

I think @newtie's advice of locking externally at 30 and unlimited in sim would be your best option.

Unlocked in the sim will provide the best option of achieving maximum frames while locking externally will keep the frame rate from consuming all your resources.

The problem is P3D is a heavy consumer of both CPU and GPU, even with my sim locked at 30 fps (via vsync) I can still overload both CPU and GPU and run out of resources thus causing frames to drop.

Also when moving through the 3D world some areas or views may require more or less resources to render thus will lower or increase frame rates.

There are multiple tools available for managing the locking of frame rates externally, NVidia Control Panel has one, the NVidia Inspector is another and the Riva Tuner Statistics Server rounds them out.

I've included a link showing the use of RTSS.

Cheers

I used RTSS @ 1/2 refresh for years; silky smooth.

With my new machine, NVCP locked at 30 with a 30hz monitor does the trick.

I have done that, locking outside and inside unlimited.

Is better now, and I guess, more is not possible with my old machine

Thanks all

I am running V6 and with NVCP using 1/2 refresh with unlimited in sim, I would get Terrian.dll crashes.

30FPS looked in NVCP with unlimited in sim, no issues at all.
