Preaching to the choir.

Just agreeing with your YMMV comment..

FWIW - For me, I have always found that setting the graphics setting in the GUI to unlimited (and thus the FFTF value to 0.01) made for smoother performance.  However, this did cause autogen to display late at times.  I finally tried the FFTF Dynamic program and it solved this by adjusting the FFTF to higher values as the altitude increased.  Smooth performance and no more late autogen.

Others swear by locked FPS so to each their own.  Just what I found that works for me.

Excellent point! Many users swear by that addon. It does a great job in eliminating the lost AG.

Not weird at all. The FFTF is NOT a one size fits all tweak and FFTF- 0.15 will easily cause issues in a system that is challenged. The valid ranges are from 0.10 to 0.99 with a default of 0.33 and depending on your system .15 may or may not work.

We have enough people blindly copying settings and running into problems. If one wants to post a "tweak" it would be best explaining the setting and noting what works for you.

IMHO, the weird response was yours.

Most config tweaks are not a one size fits all.  The FFTF tweak is one of the most useful tweaks there is.  To label it as not useful I just found misleading.  With today’s six and eight core cpu’s a FFTF setting of 0.15 works very well on a wide range of systems.

Display]
MaintainSystemCopyOfDeviceTextures=0

This is for Multi-GPU/SLI configurations and should alleviate the case where the 2nd GPU needs to read a texture off disk.

Graphics]
ENABLE_MEMORY_OPTIMIZATION=0

reduces malloc for AG but increases memory usage

This one does a few different things. Turning it off will cut down on memory allocations needed for autogen batches at the cost of extra memory. It should also improve loading when changing airports, because it won't unload your textures before changing locations. This will result in a spike of CPU/GPU memory usage during and shortly after changing locations.

UsePools=0

=> FPS increased

FFTF=0.1 works very well for me.

This is a very old one from many years ago. Don’t know if it does anything nowadays....

[ng0057a5 6]

I know but it still works for me with FPS limited at 60.

Just try and see 😊

I do agree that 0.15 is a nice compromise between 0.1 (fps unlimited) and 0.33 (fps locked)...  Eating crow here..

Right now, given that FFTF Dynamic is MIA because of incompatibility with the V4.5. Hotfix,  0.15 is a good value to try..

Since the "word not allowed" message showed I'll just delete the entire post. All this PC nonsense is, at times, a bit much.

.. and now FFTF Dynamic has been updated to work in V4.5.1.

this is supposition, I don't use SLI..

I think this one might need to be reviewed in light of SLI on RTX cards which changed drastically. GPU memory in  SLI is now (I believe) mapped as a single flat address range whereas it used to be per card. if the 'system copy' was an aid to SLI loading textures in two address ranges then that might not be necessary any more.

It did not take long to get into the FFTF debate. All I will say is watch this video here on these very forums and draw your own conclusions to if 0.01 is a valid number. 

 

I use 3 tweaks and they are system dependent.

1) An AM to make P3D run on my main cores

2) Use in W7 task manager to put all addons CP/ASP4/EF/ProATC on the threads not used see #1

3) As I never have any texture loading problems at all I can spare unnecessarily wasted CPU usage and use FFTF 0.01 to make my sim run like it's on unlimited but is locked at 26 within P3D (Sorry Vic I respectfully disagree with you on that one)

NOTE: Anything from Rob A is worth taking note of.

Finished the first phase of the full installation of 4.5 HF1 and I'm so glad that all the features of PTA finally work.

I still see tiles loading in the distance. Is there a tweak that will stop the distant tile loading.

Thanks!
