For those that have a blurry ground texture problem...are you running a custom LOD?

Recommended Posts

I started to get blurries, in going anything over the stock LOD of 6.5. The higher I went..the worse the total rendering was. 

 

I went back to the stock 6.5, and got crystal clear once more.  So,  if you do have blurred textures, might you be running a higher LOD than what the sim is designed for?

 

I'm keeping mine at 6.5, because I had always set FSX from it's stock 4.5, to 6.5 anyways...and was quite happy with the result.

 

Hope this helps,

6.5 is the max limit for P3dv2 on-wards, LM said they cannot unlock the LOD similar to what FSX has because it opens pandora`s box to more problems, if you want to try and search the LM forums for more on the topic there are several previous posts.

Wait what? I only set LOD radius to ultra in the settings. But in the config it shows as 8.5? I assumed that was correct for the ultra setting. I did not manually change or edit that.

 

Gonna change it back to 6.5 and see if the blurries go away.

 

Thanks for the tip.

After you mentioned that you were set to 8.5...I was of course curious. So, I set up a test flight scenario.  I then increased to 8.5...and in fact had blurries. I then drop out of the sim, reduced to 7.5, and pretty much the same. I then went back to what P3D v3.2 was coded to run at...(6.5) and then did the test run.  Back to clear shots. So...I won't be mucking around with the LOD any further. In FSX I did go from 4.5 to 6.5 with no blur for the 2 increment bump-up...but P3D is not FSX, lol.

 

Cheers,

That must be it then. Haven't had the time to test it out but I'm gonna revert to an AM of 116 and give it a shot. It's odd though I didn't change that value manually. Could be some addon that did that automatically.

 

Which also means for some reason v 3.0-3.1 could handle that LOD of 8.5? There were no blurries and it does seem like it loads more as opposed to 6.5. I think it does work actually since the sim doesn't revert it to 6.5 if you set it at 8.5. And the LOD setting under options changes from "MAX" to a blank text.

Is the default LOD 5.5 in P3D v3.2? Or 6.5? Thanks

I use the default LOD and AM 116 and have clear textures throughout. The only strange thing I notice is after a flight, when on finals with runway in sight, the the terrain becomes blurry. Only when the runway is in sight after a flight. During the flight, textures are sharp and clear.

How are you guys changing the LOD? is this done from within the sim or a manual edit to the config file ?

You do it from within the .cftg file..but...P3D v3.2 is baked in at 6.5 and locked...

You may be doing it in the cfg but you SHOULD be doing it from within the sim. No need to use to edit the cfg for this. Stick with the ingame settings and you shouldn't have any problems. And the sim is not locked at 6.5. Every setting in the sim results in a different LOD.

 

Sometimes I wish it was impossible to screw around in cfg's.

So I guess it's not entirely a LOD issue then. Have you tried different AMs? Ones that use more cores, 245,248 etc.

Yes. I use "High" which results in 4.5, the max which was available from the GUI in FSX and P3D 1.x. In FSX, setting it above 4.5 was just asking for trouble (blurries, OOMs) so I keep it sane at 4.5 in P3D v2/3 as well.

When high LOD is used, or intense scenery, there's a case for increasing FFTF, maybe try 0.4. Use of FFTF below 0.3 reduces the usefulness of a fourth sim job. The AMs 116 (three cores) and 85 (four cores), and their equivalents (like 170 and 184), can't be beat on the four core +HT. But performance can be scuppered by allowing addon exe activity onto the core with the first unmasked bit, core zero in the case of AM-85, and core 1 in the case of AM=116. In the case of AM=116, also avoid addon exe activity on core 2 with LPs 4 and 5. Unmasking five LPs (as in AM=248) should be avoided, these always reduce performance.

Using 116 and unlimited frames yields blurries for me. FFTF only works in locked fps yes?

 

Not sure if it's just a coincidence but I notice maxed out activity in both the scenery rendering cores in line with when the blurries happen.

FFTF works all the time, it is a ratio of background to foreground processing.

 

There's very little difference going from four cores AM=85 to three cores AM=116. If you have a maxed core it cannot do any more processing. AM=116 puts job 2 and job 3 onto a core and when your scenery rendering is maxing the job 2 is idle anyway so in that way it affects the total sim performance by only a few percent to place 2 and 3 on a core together. Your problem is most likely with other processes and where they run.

CPU idle usage is normal so that isn't the likely cause. All other running addons are on core 0.

 

What I meant is that the two LPs doing the scenery are being maxed out not the core (being technical).

 

This exact config didn't yield any blurries or other issues with 3.1. Something seems to have changed.

P3D has changed a bit under the hood, and slightly in the way its processes are consuming the cores. Even so it's still the same in terms of AMs applied. I've been testing 01,11,01,00,00,00=1856 (116 configuration 4LP 3 core) vs 01,01,01,01,00,00=1360 (85 configuration 4LP 4 core) on the six core just now, keeping addons out of the way on the spare cores, and it needs some care to see the differences in operation. Running a heavy load of ORBX, PMDG, Aerosoft, etc. with a high autogen, yielding around 30fps, to show small differences as larger differences, the 4LP four core configuration is barely a few percent better at handling it than the 4LP three core configuration. The main differences will come from how the other processes are laid out. However, a big overhead from a .dll can make a difference where the 4LP four core can help. Sometimes you need to go to 4LP four cores and take more care in where the addon exe's go. The fact you get some LPs maxing seems OK, unless you are hitting something buggy in code or scenery that's too much for it to chew on all at once.

That's what I think it might be. Something in the code is bugged. Why I mention the LPs being maxed out is because in 3.0/3.1 they never maxed out at the same settings. They will hit 80-90% sometimes but never 100% like in 3.2, and I'm inclined to think this may result in the slow loading textures and blurries.

 

When you say .dll do you mean it could be fsuipc or something else that doesn't run on a .exe process?

Maybe, Dlls load up the sim in the LPs allocated in the AM.

I suppose there is no way to shift them to other cores is there? Might update fsuipc and give it another shot. Could be the objectflow.dll from Orbx too unfortunately there's no real way of determining the culprit in this case.

On the four core +HT AM=221 (11,01,11,01) gives 6 LPs, and it's possible it can help with those dlls. Job 1 goes to core zero like with AM=85, puts jobs 2 and 3 onto core 1, load up addons on core 2 and 3, LPs 5,6,7. Without addons this would not beat 85 or 116, but presents a wider affinity space for the sim sub-processes and less to the addon exe's.

 

...there's still only four cores used by the sim, it's just some jobs will have the advantage of hyperthreading, so it's not a lot but it can work a little in some cases.

Thanks for all the help. Will give it a go if the blurries persist.

 

Right now doing a bit of testing with LOD=6.5 set and AM=184 (same as 116 with first job on 2nd LP instead), no blurries yet. ASN, GSX and EZCA set to Core 0. Scenery threads not peaking out yet. 

 

Might have been the LOD=8.5 that ruined something.

 

Edit : Nevermind, spoke too soon. Blurries right under my wing.

Steve, I have AM 116. My scenery is clear until towards the end of a flight....where it begins to blur...what affinity do you think I should use for addons while using P3D....i.e. which cores to use?
