P3D V 4.5 useful tweaks ?

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

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

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

:smile:

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.

 

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!

Could you please elaborate?

I have 8 cores, how does this apply in practice?

If you have 8 real cores, no AM is required.

If you have 4 real cores (8 with HT on)

[JOBSCHEDULER]
AffinityMask=254

is a good choice.

I tried FIBER_FRAME_TIME_FRACTION=0.15 and it worked quite well. I've had a scenery that I downloaded somewhere, KOKC (Oklahoma City World Airport) and I normally fly out of an airport about 12 miles s. of there. (KWPA) and KOKC has always been full of black bldgs. when it comes into view. It doesn't do that since I change the fiber_frame thing.

Using a set number like 0.15 is a nice compromise, but I'm sure that those using the FFTF Dynamic add-on are getting more efficient results because the FFTF number is changed over the course of the flight.

In the past with the former versions there were useful tips here and on YT for tweaking the "prepar3D.cfg" file.

For example: 

[DISPLAY]
TEXTURE_BANDWIDTH_MULT=160 

I've found increasing TEXTURE_BANDWIDTH_MULT to the point of it no longer making a difference to the frame rate, is useful.

Surprisingly on my workstation I managed to increase the value to 960 before it no longer made any difference to the FPS.

Noting TEXTURE_BANDWIDTH_MULT and its value doesn't apply if you run P3D with a target frame rate of unlimited.

After reaching the max useful value I'm then able to set an internal P3D target of 30 FPS and have P3D actually maintain 30 FPS.

Quite a useful tweak IMHO.

Plus you can disable it by simply setting the P3D target frame rate to unlimited.

Cheers
