Question regarding Prepar3d 2.5 behavior

Recommended Posts

Hello everyone,

 

I have been a lurker of these forums for about 3 years now, but it is only now that I have decided to make my first post, and unfortunately it is with a question.

 

I have been an FSX user for around 4 years, but recently I was convinced by a fellow simmer that Prepar3d is worth the upgrade, especially since version 2.5 turned out to be very polished. For that reason I decided to give it a try with the Academic version. I have installed a few of my most used add-ons (REX 4, FTX Global and Vector, Soft Clouds and KMIA from LatinVFR) to use with this version of the simulator.

 

Even though everything looked very promising with the use of DX11, tesselation, better lighting and overall graphical improvement over FSX, I have come to notice a few things that are a little bit disappointing in my point of view.

 

To illustrate what I mean, I will add a picture to the post:

As you can see, everything above that red line is completely blurred. Is it normal P3d 2.5 behavior to have such a low level of detail radius? I have tried to increase this in the simulator display options and also through the Prepar3d.cfg file, but these tweaks have not had any effect. 

 

Another problem that I am having is that, even though I may get used to live with the short radius of detail, as soon as I start moving towards these "blurries" the buildings pop up in a very noticeable way. 

 

Here are my computer specs"

 

Processor: Intel i7 4790k @ 4.4 GHz

Graphics: EVGA GTX 980 Superclocked

RAM: 8 GB

Prepar3d is installed on a 1TB Western Digital Black

 

That picture was taken using one of the default GA aircraft. 

 

My graphics settings are as follows:

 

FXAA: Off (Set through Inspector)

MSAA: 8 samples

Texture Filtering: Anisotropic x16

Texture Quality: Medium (1024x1024)

Resolution: 1920x1080x32

Vsync: Off (Set through Inspector)

Target Framerate: 30

Tesselation Enabled

 

Lastly, these are my autogen settings:

Is this normal behavior, or is there something wrong with my system?

 

 

Thank you all!

It may well be Level of Detail radius, i only run at 3.5, increasing this setting makes things look better at a distance but has a significant VAS impact.  Some people (Rob) seem to be able to run silly settings at something like 6.5, no idea how.

My current LOD Radius setting is 6.5. I have tried increasing that to 9.5 even, and I see no change. I also read somewhere on this forum that that setting doesn't do anything anymore on P3d since 2.4

This not normal with your rig and that res monitor and I'm a bit perplexed why this is happening - makes no sense but try not using NI and maybe a nice clean install of your video diver - something is not adding up - do you have all of your motherboard drivers up to date also make sure vector is not messing something up - I would see whats up before installing that and go from there - you need to install stuff into P3D very carefully one at a time

 

6.5 is max that P3D will do but this is not your problem its something else - lod has nothing to do with that much blur

 

Did you overclock your video card - I have seen this on an OC - problem is you may have done damage that will not be fixed unless you replace that card

I will try formatting this drive and performing a clean install of everything, including video drivers. Will report back guys!

 

Also, I will test this without any add-ons, and install one by one as I test. Thanks for your replies. Is there anything else I should be looking at?

Dont load vector until your sim is stable and looking good as it does induce stutters

 

If you are formatting make sure you load current motherboard drivers and windows updates and use takeownership program to give rights to all of your P3D folders - its free and works great - double click reg file from the download zip file after you highlight the P3D folder and right mouse click and pick take ownership and let it finish before getting out of it as sometimes you think its done but its not

 

You did not answer if you overclocked that card - did you ? that will cause this

The card is not overclocked.

 

And George, thank you for those! I will definitely give your settings a try.

Try George's settings first. I am going to suggest again to the Moderators that his post be made a sticky in the P3d General forum as it would save new users a lot of time and trouble.

 

The tendency with P3d 2 is that because it can look so beautiful is for new users to crank all the settings up to the max and then back them off randomly out of frustration. A better option is to start with very sensible settings and then increase each setting independently if you need to do so.George's approach has already done that for people like yourself who have a high end CPU and GPU combo.

Bad news guys :( I just formatted the whole machine. New drivers, new installation without addons, just George's P3D settings. And this is straight from the default flight:

And as I move in, they start popping up one by one

I take off, I see very nice autogen next to the airport. Take a right, and cross the waterbody and see those really ugly blurries with no autogen on. Is there something else I should be looking at?

 

EDIT: Here are some pictures of my CPU usage and temperatures during this test flight with vanilla P3D 2.5 on a new installation

This is why I'm unsure about the future of P3D...

It's been some years now and several version of P3D.
Yes, some nice effects have been added like reflections and shadows... but in the end, the underlying program is still the same.

 

It's still doesn't work out of the box.

You still end up fiddling with ini files..trying combinations of parameters, FFTF, affinitymask blabla.

Still occasional error, conflict, bug, crash.

Still graphics problems, spinning clouds or other glitches.

Still fighting for every FPS even with high-end 6/8 cores and GTX 980 GPU's which can run every AAA title almost at at 1440p maxed out.

 

And for what? Water still looks better in FSX with REX than in P3D with REX.

With steam edition, they are probably just as stable.

Doesn't require you to pay twice for the same addon.

 

This flightsim needs a completely new engine, supporting DirectX 12 or Vulcan.

Being CPU and drawcall bound, DX12 or vulcan are the ultimate solution for this genre.

 

But perhaps P3D can pull it off........

Jose we have the same hardware (apart from some minor game players) I just recently shared my settings and 'tweaks'

Maybe you can give them a try? report back with pros/cons

 

http://forum.avsim.net/topic/465098-thought-i-would-share-my-p3d-v2512944-settings/#entry3204404

 

Thanks for that video George, I was pretty happy with my own settings until I saw yours. I mean, our settings were fairly similar but I'm going to give yours a try for a while and see how it works out. (i5 3570k and 970)

Something's definitely wrong here Jose, *everything* looks blurry. Make sure FXAA is switched off. Also make sure Anisotropic Filtering is forced to 16x. Something, somewhere is getting overridden, P3D shouldn't look like that on your hardware.

Something very wrong here and its not P3D - something video or hardware wise must be causing this - and I have not seen anything close posted here showing such bad graphics

Well... Clearly things are still being sorted which might be adding a negative element to ones experience. But patience is needed.... The tinkering pays off....

I agree, it might be worthwhile to check your system with a graphics benchmark app to see what happens. MSI Kombustor 3.5 is a nice simple app:

There are a number of other similar apps that will stress the GPU.

Great point Jay - you can stress the card and it will probably crash - there is your answer your video card is fried - I did benchmark test on one of my past cards and proved to me my card was junk - it couldnt finish the test - good call Jay

Jose Perdomo. You are not alone. Same situation here. Or was really... I have given up. I was not enjoying it and I was not smart enough to fix it. Tried all tweaks and setting and sometimes I thought it was better... but no, there is a lot off placebo involved in flight sim, that is for sure.

Find it hard to believe that there is something wrong with the hardware when all other sims are working very fine. ( X Plane, DCS, COD) 

(oh dear I wish I could have kept  my P3D aircrafts for X plane  :tongue: )

 

If you find out what is wrong I might have a go at it again...

But I´m not going to try any more obsolete tweaks or "fix everything settings".

Did I miss something I do not see where he posted (x plane dcs and cod) is fine ? - I will admit after loading 2.5 up that the AA is not as good as it use to be and distance seems a bit blurry compared to 2.4 - as I am waiting on UTX V2 installer to be updated I haven't really done much simming and did not pick up on this till now looking for issues - pm sent to Rob on this see what he thinks

Thank you all for some of your tips. Although this is all very discouraging, I still sort of want to believe in the promise of P3D. 

 

I have performed a stress test on the card as recommended by a few of you.

 

These are the results:

 

http://i.gyazo.com/4caf27ce3a1c4c35255431585a0bcb7f.jpg

 

The card as you can see, ran perfectly stable, averaging between 154 and 184 frame depending on the position on the scene. Temperatures never surpassed 74C. That rules out the card. Now, what program should I use to stress my processor?

 

EDIT: I was not convinced by that other stress test due to the fact that it's only based on OpenGL performance, so I loaded Unigine Valley running on DX11, Ultra HD settings at 1080p with Vsync off.

The card performed just fine, and in comparison to other people with the same card using the same benchmarking tool, I am getting higher scores and better frames.So I am ruling out the card in this one.

Well you did a great job so lets look elsewhere I was not happy with what I am seeing in 2.5 compared to 2.4 so I installed nvidia driver 347.88 restart your computer make sure you have not edited your p3d cfg file as I added affinity mask and forgot about it - deleted it out and it was better - go to program settings as shown in pic then only change what you see - add the exe from p3d I chose to grab the desktop exe - then in P3D 8 samples and 16x aa - 1024 or 2048 textures  - fxaa is your choice - no vsync or triple buffering - HIT APPLY AFTER DONE - try this helped me quite a bit - I think I had a driver issue - this is why I have a very slim install until I start loading stuff up - rex - some mesh if you want - a good payware aircraft and ftx global if you have it - check textures before and after global install (important) this will get you started - get it running correctly with these addons first - report back so we can continue

Thank you Richard, I will try that right now. Also, here is a recent screencap before performing the steps you've mentioned above.

Is the right side of the red line the proper quality, or is that still blurry?

 

 

I think it will be better if you do what I explained buddy :) there was no red line - go for it - p3d is different it does not like a lot of tweaking - video or p3d.cfg file - its not like fsx due to the way it renders in full screen - fsx did not do it this way

Can someone send post a reference picture of this exact scene during the default flight? Just bank right after take-off, this is how I'm getting these pictures. I just want to compare what it's supposed to look like
