Long Textures' Load Times

[G-YMML1 580]

Good morning,

 

While I have been able to achieve more or less reasonable FPS and VAS usage even at the airports such as EGLL/KJFK with 100% custom made traffic, REX(512-clouds), PMDG, UTX and FTXG, one thing that still drives me mad is a long time required for objects to get proper textures. When you switch view it takes sometimes more than 10-30 seconds for textures to show up. You make another view switch and it happens all over again. In NVI I changed SGSAA from x4 to none and nothing has changed.

 

My specs in the signature. I still have 2-yeas old 780GTX, so perhaps 980 would help? 

 

What do you think?

 

Thanks

I think if it is taking 10-30 seconds to load a view you have overloaded your system, your P3D install needs a second look or one of those addons is eating up your flight.  I have a 780 and when I switch views with 100% AI with payware airports and the view may take, yes up to maybe a second but probably more like a split-second to load.

 

Try a test removing one of those addons in succession and see if there is a FPS hog in there.

30 seconds is huge. I don't get that even at UK2000 EGLL or EGKK and those airports are detailed! Do what Clutch Cargo (interesting name) suggest and eliminate an add-on, disabling one at a time then re-enabling

FFTF in your configuration by any chance?

Do you have FFTF set to a very low value (e.g. 0.01)? [Edit: Neil beat me to it...]

 

Some other cfg tweaks that could help:

GlobalTerrainView=1

TextureMaxLoad=15 (default is 3; try any multiples of 3 between 6 and 30)

TEXTURE_BANDWIDTH_MULT=80 (default is 30)

Thanks for the responses, folks

 

Nope, don't have any other additions to scenery.cfg except for OPTIMIZER line.

 

Planning to test the below-mentioned tricks later tonight. Please comment on them if you're think that these tricks deserve attention.

I agree with this. I've had this issue before in the past. Once I turned down my settings to something my system could handle, it went away.

Folks,

 

Do I still need BufferPools entry for P3D? I have this one

 

[bUFFERPOOLS]

UsePools=1

PoolSize=5000000

[DylanM 1,069]

I'd run without it...

Won't help in there. :rolleyes:

 

P3D is no longer FSX. If the "tricks" are recommended by Lockheed Martin consider them, if not, forget them.

 

Delete your "prepar3d.cfg" and let P3D rebuild it upon startup. Add the optimize parts=1 line and then don't touch it.

 

SSD rather than the GTX980.  A GTX780 seems more than capable to handle P3Dv2.5.
