FFPS:FFTF question

Recommended Posts

Posted (edited)

 

I have been a beta tester for this product  and many of my suggestions were inplemented.

When flying very low or on the ground at a very detailed airport the FFTF value is low. Maximum performance. 

When flying and climbing the FFTF value will rise so blurries will be prevented.

Also there is the possibility of using min/max framerates to dynamically change the FFTF value.

All settings/values can be set to your preferences.

Most of you know that I have a triple view setup and I have to be very carefull with my settings to avoid framerate loss or experiencing blurries.

I now can fly over FTX Germany + AS EDDF Pro + Prealsoft Frankfurt in bad weather with Nico’s Live Traffic without very low fps and without blurries.  My settings : AGL mode , FFTF 0.05 on the ground going up to 0.4 at 4000 ft.

Not often I am really impressed by new Fs products , but this is something that I am using with every flight over the last couple of months and it still does..,

 

Regards, Gerard

Thanks for HU. It sounds promising, but I'm a bit hesitant, as I have not so good experiences with "on-flight-tweakers" until now. But I will check the product description and wait for other comments.

I used their product "Fiber Accelerator" for FSX, which is at least very similar, and I liked it. Never flew without.

Received the email notification yesterday. Purchased and installed last night. Can’t wait to set it up and give it a try later today. Sounds very promising and based on known facts and experiences in the FS Community. However, the fact that the FFTF value is adjusted dynamically during a flight scenario is a novel approach and, without doubt, is what persuaded me to go ahead. Fingers crossed!

Thanks Michael Moe 

1.)    Unlimited frames + VSync enabled + TB enabled

2.)    Unlimited frames + VSync enabled + TB enabled + external limiter

3.)    Unlimited frames + VSync disabled + TB disabled

4.)    Locked frames  ( VSync + TB settings are ignored  )

There are two options for dynamic FFTF calculation. Frames range and AGL height range.

Frames range option: 

Suggested for unlimited frames + VSync disabled + TB disabled.   

You set the minimum and the maximum frames + FFTF range + times you want FFTF to be updated per sec to Flight Simulator. 

An example can be: Min frames=24, Max Frames=28, FFTF minimum=0.05, FFTF maximum=0.33, times to update per second=1. 

In this case, at 24 frames FFTF will be 0.05, at 26 frames FFTF will be around 0.19 and at 28 frames, FFTF will be 0.33. Below minimum frames set, FFTF will always be 0.05 while above max frames set, FFTF will always be 0.33. 

 

AGL height range option :

Suggested for the rest options. You set the minimum and maximum AGL altitude + FFTF range. (Times to update per second is not available for AGL height option).  

An example can be: AGL Min=0 feet, AGL Max=5000 feet, FFTF minimum=0.05, FFTF maximum=0.33. 

In this case at 0 feet, FFTF will be 0.05, at 2500 feet FFTF will be 0.19 and at 5000 feet, FFTF will be 0.33. Above 5000 feet FFTF will always be 0.33. 

Every time that the application calculates the new FFTF immediately updates the new FFTF value to Flight Simulator. This is the main reason that we do not need any timer option in this case.

Watch the link at bottom first so you don't know fully what FFTF does

And this from LM

[MAIN]

FIBER_FRAME_TIME_FRACTION=0.33

Non-Default entry. This entry will not exist in your Prepar3D.cfg file by default and must be added to the file.

Performance Tuning Tip:

This setting, which defaults to a value of .33 (33%), defines the percentage of each frame that is devoted to loading scenery. Increasing this number can reduce "the blurries", but it can cause stutters, and can also reduce the overall frame rate. Try reducing the number to the lowest level where you still get smooth scenery paging. This will vary depending on disk speed as well as the type of flying, as well as the selected scenery settings.

Also

If you run unlimited even if you have never manually added the tweak your basically setting

 [MAIN]

FIBER_FRAME_TIME_FRACTION=0.01

With any FPS set even 60 you basically adding again even if you don't see the entry, its there but hidden unless you add it manually.

[MAIN]

FIBER_FRAME_TIME_FRACTION=0.33

I suggest you watch this video to understand it more.

I lock my FPS (24) and have no texture loading problems with framed lock and this added in config.

 [MAIN]

FIBER_FRAME_TIME_FRACTION=0.01

Unless you have bad texture loading problems why you would need to give 0.4=40% per second to loading textures is beyond be. Because texture loading must be very bad to go beyond even the default .33 =33%.

Also when is cruise, it's the least demanding part of your flight, so texture loading should not be a problem. 

Photoreal is the only reason I could think off to dedicate so much of anyone's cpu time per second to try and load the current less perfect loading of photoreal.

Also remember you can add whatever value you like to try manually, but ofc it will not change dynamically.

I have the smoothest with VSYNC on and unlimited so the AGL method seems like the way to test here on a 25hz4k tv.

Will buy later and test 0.4 above 5000feet

Enjoy the FPS hit above 5000ft then. Do you have a texture loading problem? If not you have no reason to try anything.

Hi David 

Not sure but my SLI 970 setup makes high resolution a stopper with alot of places in 4K. Maybe i should try manually first by adding FFTF .

Thanks Michael Moe 

I need a 11gb videocard 🤣😁

I still cant fly the FSL A320 into most large aiports, SFO,LAX,LHR,LGW,STN with 4k without stuttering...   

Is this application going to help that >??

Also if it messes with plays with configs files will the fsl start up message keep coming up ?

and finally are we still going to be faffing around with tweaks in 10 years time ??  

it all gives me a headache.

It will give you fps like with Unlimited + FFTF 0.01 on the ground and better terrain loading while flying ( higher FFTF value ).

Up to now it was a static FFTF , so If you used 0.01 because of a heavy airport you could suffer from blurries when flying.  This utility solves that.

Is this using a hook into the sim?  Is it tied to specific version numbers?

So.. can you tell me what line i need to put in the config file if I buy this application.

and is it going to help with 4k stuttering at big airports ?? im guessing not. 

many thanks, I apolgise in advanced for being short. 

but im sick of these bloody tweaks

I swear if i said I had a cat, someone would pop up and say they got 3 Peruvian tigers.

Hi Gerard,

Any chance you can elaborate for us on which of your suggestions were implemented? 

Over the years we have come to know that very little gets past you 😀. Like me, and within the limits of our respective capabilities, you are blessed (?) with a mind that drives a need for a greater understanding of how things work and what needs to be done to make them work well. Your passion for Flight Simulation is evident and certainly beyond any dIspute. So, any recommendation from your good self would be most welcome and should be taken seriously.

There is a danger here that some will be making the assumption that this product is the answer to all our woes and will allow good performance in all situations with all options checked and settings maximised. Clearly this is unrealistic and certainly not the case. As before, careful attention to appropriate slider settings will remain mandatory for consistent performance.

My rig spec is quite strong by today’s standards. I don’t experience many performance issues and rarely see any blurries. Most of my flying is done away from busy hubs and when I do approach and enter more demanding areas I have to switch to a more conservative profile to maintain frame rates at acceptable levels (preferably 30+). My hope is that this utility will allow seamless transitions while using my current settings profile for general use (both day and night) without the need to halt the sim and make a switch.

Am I to understand that this utility is best used with an unlimited frame rate setting or can it be used with a fixed value like 30 which is my preference while away from very dense scenery areas? Again, having to switch to unlimited to bring up the frame rate, as the situation demands, is a slight annoyance so it would be good if this utility would allow me to side-step this requirement.

Regards,

Mike

Hi Mike,

The sole purpose is to have the best of 2 ways :

1 Maximum performance on the ground and at approach ( most of the time heavy scenery , like a major airport and a large city nearby )

2 Better terrain loading than with FFTF at 0.01  (  Fighting blurries, loosing AG when flying )     

I use the program with a fixed framerate in P3D icw with AGL mode.

You set the values to your needs.

Eg : You could set 0.05 on the ground and 0.15 at 10.000 ft . The program will dynamically change the values form 0.05 to 0.15 when climbing and the other way round when descending.

If you are happy with what you see without the program then that is also good. I have experienced less microstutters when flying through many clouds at a higher FFTF value.

I don't see the point in setting the FFTF dynamically.

 

Either you run unlimited FPS (and use VSync to limit the frames to give a smooth experience), then reducing the FFTF won't increase the FPS, so there is no need for an FFTF setting with unlimited FPS.

 

Or you use an FPS limit. Then you can statically set FFTF=0.01 to maximize your FPS. FFTF=0.01 won't lead to blurries as long as your FPS do not drop below the set limit. Only when you cannot reach your FPS limit, that low FFTF setting might lead to blurries. Increasing the FFTF setting in that situation might help with blurries but will decrease your FPS even more.

And you don't want to be in that situation anyway because FPS dropping below the limit will also lead to stutters. A proper sim setup for a smooth experience should always ensure that the FPS never drop below the set limit.

 

So with a proper sim setup (i.e. either unlimited with VSync on or an FPS limit - in both cases all other settings so that the FPS will never drop below that limit) I see no benefit of changing the FFTF setting dynamically.

At least that is my experience after years of testing different FFTF settings in all kinds of setups.

 

A revolutionary achievement would be if they managed to change the autogen distance / density settings dynamically - but that seems to be impossible right now.

Uimited = 0.01 without setting the FFTFLocked is by default always 0.33

Try FTX Germany + Prealsoft Frankfurt + AS MAP EDDF Pro + Lots of Traffic + multiple cloud layers + rain or snow and see what it does to your Sim. 

If you use 0.01 with high settings you will experience blurries when flying at lower altitude because the Sim does not have enough time for terrain loading. 

Using this program I was able to solve the above issue on my triple screen setup.

Surely the in Sim settings play a very big role here. If you have a good balance in performance - loading than that is good for you. Just stay with it as you are right now.

This is for people experiencing blurries because of a too low FFTF value and/or experiencing stutters because of a too high FFTF value ( because they needed more terrain loading time )

This is for people who want maximum fps at the airport and the best looking terrain when flying...

This is for people who want just that little more. I just happened to be one of them and had the opportunity to give the development team suggestions as a beta tester.

regards, Gerard
