I've been trying out the program. It seems like it might be quite good and helpful. There's a little confusion in the manual, do you start P3D first and then start FFTF or does it start automatically with P3D?

You start it before or after starting P3D.

You can minimize it to the tray.. but leave it running as long as you need it.

I use FSUIPC to start it automatically with P3D using the run= facility.

Thanks Bert! I'll maybe have to check that out! Like I said, I've basically been doing that manually by switching from unlimited to locked 30 and back again, but it would be nice to have that adjustment made automatically.

Now you get the same performance with limited fps as without. Have fun, and welcome to the world of cfg tweaks.

Ha ya. Well, I'm definitely not new to the tweaking world... not an expert... but definitely not new. Back in the FSX days, like everyone else, I played around with a lot of different settings and tweaks including the FFTF in the cfg. Since switching to P3dv4 right after it came out, I have done minimal tweaking besides the settings within p3d itself. I have definitely played with a lot of settings and done some tweaking, but keep it to a minimum.

I have FFTF shortcut on the taskbar start P3Dv4.5 at the airport then start FFTF, also have STB on the taskbar.

I also found playing with the settings that as I climb higher FFTF will go over 30, I have seen it go from on the ground 0.01 to 48 at 15000ft ORBX and UK2000 airports.

regarding FFTF Dynamic I have the following question:

If I have Vsync On and TB On, limited FR at 30, FFTF will run whatever number I have set up in my AGL scenario.

Now, If I still run Vsync On and TB On and Unlimited FR, will FFTF dynamic still work?

Only values 0.01 - 0.99 work. Not above. You should use something between 0.01 - 0.4.

Yes, it should.  If you set FFTF with an unlimited frame rate target in the Prepar3d.cfg file, it apparently won't have an effect, but the Dynamic FFTF program appears to be doing something to the sim internally that allows it to work with unlimited frame rates (and FSPS explicitly states that it does work with VSync/TB/Unlimited set).  I tested it in that config some time back with P3Dv4.3 and concluded that it was still working with an unlimited frame rate setting.

Hi,

Thank you, I just bought it, installed it, tried it........adopted it. Impressive!

I tried it with Netherlands HD + A2A Bonanza, after a while I had some blurred at 1500ft. It must be said that I had loaded the mule a little bit (on the right, among other things with the autogen). It was a first test under extreme conditions. I should be able to refine the settings of FFTF and P3Dv4.5.

FFTF settings: Frames Range >24<30

1time/Sec

I have not yet tested AGL RF

Please, some more comments of people using FSPS - FFTF Dynamic? Is there a noticeable improvement? Thanks.

How many more comments would you like? There’s the first page of this thread plus dozens of other posts you can search for. 

If I am not wrong, only a couple of people wrote in this thread about this addon and it's not completely clear if it gives some real improvements...

James Goggi

It gives real improvements if you are low in FPS for certain scenarios. That is what I use it for: on heavy scenarios (EGLL, LSZH, EDDF with custom AI traffic and bad weather), it makes in my case the difference between stuttery and choppy 18-20FPS and smooth and fluent 25-28FPS when using AGL mode with FFTF=0.01 below 5000ft and everywhere else FFTF=0.33 (I use the internal FPS limiter set to 30, btw). However, what I could not entirely solve yet is the question whether or not using FFTF Dynamic has any adverse effect on autogen loading and blurries when taking off from such a heavy scenario airport. So far, I never observed any adverse effects, but I did not test it extensively... Furthermore, I did not yet (and maybe never will, as I am happy how my sim performs currently) test if I would get even better results using FFTF Dynamic combined with "unlimited" setting inside P3D.

Last, what is true also regarding FFTF Dynamic: it is not all about FPS. Since I accepted this fact and limited my FPS internally to 30, I have a very smooth simulator without blurries or other issues and yet it feels smooth in most situations, even if FPS are between 25 and 30 where it would have been above 40 when using unlimited. I must admit that I now prefer more or less constant 25-30FPS over an average of 40 but fluctuations between 25 and 55FPS, which really results in stuttery visuals.

A few questions for you guys on FFTF Dynamic...

1) Is FFTF Dynamic something you have to set every time you load the sim or does it save your settings?

2) Can you save and select different profiles, say one for general aviation and one for airline flights? 

3) Can you set multiple "layers"? Some of you have said you have it set for 0.1 below 5,000 ft and 0.33 above that. Can you do more splits, say 0.1 below 1,000 ft, 0.33 between 1,000 and 6,000, and 0.1 again above 6,000? 

Thanks!
