Never had any positive results adding TEXTUREMAXLOAD and changing TEXTURE_BANDWIDTH_MULT in FSX and also in P3D v3. Only tweak I found very useful is AffinityMask, and it is all because some apps are hogs at Core 0.

 

 

Were you getting slow loading textures (split second) at only large airports as I have or the whole scenery in general?

Yes, like FT YSSY, EGLL etc. Now it is all good.

Nice work Julian. Good idea to try that since it can find a sweet spot. Depends on a lot of factors, the fps and scenery complexity, screen size...

Spot on Steve. That was the only fly in the ointment. Always appreciate your advice

Hmm interesting,thanks

 

Will test

I asked on the P3D forum back when 2.0 came out about the default TBM of 30, the LM developer that replied had said he thought that setting was depreciated but never elaborated further.

 

That P3D tweaking guide is dated back to 1.4 and doesn't appear to get updated so I wonder how much of it is still relevant.

Steve - When using a 4k monitor that only has a 30MHz refresh rate and no other isn't it a waste of time setting 30 frames limited and just go with unlimited instead?

Or should I go with 30 frames limited ff.01 and TBM of 30 with using P3d and not setting Nvidia?

Difficult to say. The NI limiter can be the cause of problems, and there are a lot of monitor types around. It's best to try with/without the limiter. But you're probably right in that setting vsync+TB+Unlimited it will aim for your 30Hz refresh frequency. Going low on FFTF can work for and against you. Looking for higher fps capability can mean less stability. Certain settings can often mean a drop of 1% fps but a gain of 2% stability.

Meh,

I have tried everything setting TBM 180 TML 6,9,12

 

Locked fps with and without sgss no AM and no FFTF

 

Still the same, l guess I can live with it. It only happens at larger airports for a split second.

Had the same issue P3dv3 onwards. Guess it's a limit of available processing power.

 

Then again in P3dv2.5 I had fps locked internally.

Awhile ago I had the same issue as OP at DD's Tallinn (EETN), fixed it by increasing texturemaxload to 30. However SimWing's EGLL still suffers briefly with the loading of textures. I have several large payware airports but only at EGLL am I seeing this.

 

For reference, here's the calculation used in P3D (when frames locked):

 

TextureMaxLoad = max(TextureMaxLoad, TextureMaxLoad*TextureBandwidthMult/LimitedFramerate).

The frames don't actually have to be fixed in the Display settings. We just plug the fps value into the formula to get bandwidth. Frame rate when running the Fixed setting is not visual frame rate, and is hard to tell when the Fixed fps slider is set below unlimited. Fixed visual frame rate produces a dead straight line if it can keep it up. I just did several runs v3.2 with unlimited and VSync off. I could see that [DISPLAY] TEXTURE_BANDWIDTH_MULT alters the characteristics of the sim. With autogen 4 and lod 4.5 TBM180 performed only slightly better than TBM30. I went up to autogen 5 and lod 5.5 and TBM30 performed a lot better than TBM180, probably because the system is topping out with such high lod/autogen.

 

After tests I amended information on my site:

 

 

[Display]

TEXTURE_BANDWIDTH_MULT=30 (Smoother frame rate with very low or no autogen and lod.)

TEXTURE_BANDWIDTH_MULT=180 (Smoother frame rate with medium+ autogen and lod.)

LOD 3.5 and Autogen 3 improved by at least 2% with TBM180 rather than TBM30. Autogen 5 and Lod 5.5 produce the opposite result as the available bandwidth is exceeded.

My level of detail radius is set to max

 

Should my TBM be at default 30?

We have some areas in P3D or FSX for that matter where ACES went all in regarding data (read still there in P3D) and is by default hard on hardware...

For Example the Toronto / London / Seattle / San Francisco / Rotterdam Areas etc.

Now throw in some 3d party detailed stuff / AI and you will see those loading issues...

You can of course minimize the loading issues with your sliders for those areas.

That's the problem. Screen size GPU type and memory available, system RAM, what fps you're running, you name it, all play a part. So it's hard to say what you'll need. However your radius is max so if you're running autogen 4/5 you would be better with 30. If you are running autogen 2/3 maybe 180 would suit. It's a tough call.

 

...I was testing around KSEA.

Understood.

Thanks for your reply, I guess it's fin.. and I'm just being a little too

Fussy.

 

Very happy how my sim is running.

 

Flightsim has come a long way.

Can only imagine what the coming years ahead will bring.

I see

I am running my sim on a 46inch lcd tv 1080p

 

2x Titans sc in sli

 

I get 30 fps at all my airport even EGLL with 3.2 it's outstanding

 

16gb ram

Enjoy the ride Mike and indeed we come from a very long way, and amazing that we discussed all this stuff back then in 2006.

Hence we used TML in 2006 lol Remember those wire frame screens...
