Old tweak still to be used in P3Dv4.4 ?

Recommended Posts

Hi,

I flew out of EDDK yesterday in the PMDG747-8F towards Dubai and noticed that my system (I7-4770K@4,6 HT off, GTX1080TI) was struggling with FTX GES at low altitude (badly need FFTF to give me 0,40-0,50 above 5000feet , as i am running unlimited FPS) and came across the old value UseGlobalTerrainView=False in the P3D.CFG  which i remember had =on so every cameras did not need to reload textures . didnt see much differents but anyone using it still ?

As i climbed out i noticed textures was getting better , also in the distance as i have used Robs tweak for texture distance.

 

Thanks

Michael Moe

I still have it in my config in P3Dv4.4, but just because it was there in v4.3 (I added it). However, never observed a real difference, but also no disadvantage, ergo it is still in my config.

The original setting was 0.33 for FFTF, I experimented with 0.01 and the region purge setting from 16 to 1 and seen a good result in 4.4

And another one posting FFTF=0.01... When do the people finally get that the lowest setting accepted by P3D is 0.1? I fear that we never get this placebo setting out of the simmers minds...

One question I have about this limit, however, is whether FFTF Dynamic, by presumably altering the value directly in program memory, is bypassing the range checks that P3D normally does for a parameter set in the Prepar3D.cfg file.

It could well be that values below 0.1 are possible using the utility.  Notably, the default lower value in v1.3 of FFTF Dynamic is 0.01--whether that's placebo or not hasn't been clearly established.

The Fact when you change it makes a difference might suggest you are correct.

Another old tweak working very well on my low end PC (i7 3700K / GTX 1060)  is UsePools=0 in the [Bufferpools] section. I really get more FPS by setting that even on 4.4.

Concerning FFTF, my best value is 0.25.

No placebo at my end Chris. I agree, have tried a host of other tweaks, 99% of which have no effect, but FFTF=0.1 works flawlessly. However, while I see no effect whatsoever for blurries from 0.01 through to 0.50 (not been higher than this) there is a distinct improvement with FPS increase and smoothness. My sim is super smooth with FFTF=0.01 but I wouldn't even consider flying without it. I'm not saying it works for others, just my own experience. Certainly no placebo effect 😉

Do you have a source for that? In my experience, 0.01 makes a difference in FPS, which means it is accepted by the sim.

Careful guys. I am not saying that FFTF has no effect and that you do not get better FPS or the impression of a smoother sim with FFTF=0.01 compared to the default value. What I am saying is that this value is not accepted by P3D and most probably automatically corrected to the next acceptable level which is 0.1 (that is the big question).

Means: if you can show me a true difference between 0.1 and 0.01, I would be really surprised.

In the P3D tips and tricks forum.

.Showing that 0.01 = like running FPS unlimited. Unlimited is known to be 0.01

Following on from the FFTF setting at 0.01 not being recognized by P3D, I was looking at FFTF Dynamic, which has a good following on here and I noticed their setting starts at 0.01 up.

Might give that program ago, especially as 50% off at Simmarket, although 4.4 update has not been released yet.

I am not into arguing with you about this statement.

But anyone who is reading this statement should check out for himself on his system if there is a difference in FPS with FFTF=0.01 and FFTF=0.1. I certainly do see a significant difference on my system.

I do too! And now FFTF.EXE is released for 4.4 I've got that going down to 0.01 when my frame rates are struggling (below 20).

Do you have to still have FPS limit set in the sim or does it handle that as well?

According to Phil Taylor ( remember him?) Aces hard coded the FFTF range from 0.10 to .99. The default is .33 No one from LM that I have talked to has confirmed they made any changes. As with other configurable settings in P3D, you can input what you wish but it will just use the nearest valid number.

This is only true for manual entries in the cfg file.

I would assume that FFTF is injecting the value into the code directly so it's quite possible that values outside of the default range are possible.

If you see a difference between 0.01 and 0.1 using the manual input to the cfg file, it is not due to the FFTF value.

Wouldn't it be great if we had a sticky with all the cfg. tweaks?

No. I just use VSync in P3D. My projectors are all 30Hz. works fine. Frame Rate limiter is set to unlimited.

I wonder if those who keep claiming FFTF=0.01 is a placebo have ever tried it themselves.

But anyway believe what you want. I rather enjoy roughly 10 % higher FPS with FFTF=0.01 compared to FFTF=0.1 with a limited frame rate than getting into an argument here.

 

What is important to me is that no user should be deterred by these statements to test it out himself.

 

BTW: SIMstarter covers a setting of 0.01 to 0.99 for the FFTF value in its Tweak-section.

Some users say that FFTF is automatically set to 0.01 if fps limiter is set to unlimited. So everything confusing here. One is saying 0.10 is lowest possible, one is saying 0.01 automatically if FPS limiter unlimited. What to believe?

Do what you want and don't worry about it. The wrong setting won't do any harm and if you like what you see - stay with it. It's not a question of wrong or right. There have been many tweaks through the years that people swore changed their sim forever. Some of those were also impossible because of the code but who cares. If the user thinks it works, it works.

No need to believe anything. Just test for yourself.

Create a demanding situation without weather and without traffic.

Set FFTF=0.1 in P3D.cfg.

Load the situation, let everything settle down.

Compare the framerate when FPS is unlimited and when FPS is limited to a value which is not reached in the actual situation (just for testing purposes - otherwise you should always set a limit which you can reach).

 

Then do the same with FFTF=0.01 and compare your results.

 

Just FYI my results would look like this:

FFTF=0.1

unlimited: 33 FPS

limited (to 40): 30 FPS

 

FFTF=0.01

unlimited: 33 FPS

limited (to 40): 33 FPS.

Wouldn't this (0.1 vs. 0.01) be a good question to ask the LM experts on their forum? No guaranty they will answer, but we could at least try. I am not at all an expert on this value (I gave up on 0.01 when I had sincere blurries a couple of years ago when nearly everyone promised this as the final cure to all diseases), thus I'd better leave it to someone more experienced to ask.

Kind regards, Michael
