Are my P3D v4.1 settings really too high?

Recommended Posts

I am getting frustration about smoothness in v4.1, sometimes it is really smooth and at 30 fps or above (when unlimited), sometimes is still smooth at panning at 25 fps but also many times I got stutters and 15-19 fps.. Tried also the 30Hz but when fps are at 20.. does not use anymore.

Even if I do not change anything, I see 30 fps and 5 minutes later, 24 fps in VC... 

To summarize, why I can have the panning so smooth even at 20 fps but sometimes at the same fps is really stuttering?

I am running a 7900X (HT off, 4.7Ghz core 0, 4.5 Ghz all other, 1080 TI FTW3, NVMe SSD 960 Pro, Win 10 Pro, 32 DDR4 @3200Mhz CL14). My settings and result are:

 

Added> TEXTURE_SIZE_EXP=10.

I am using ORBX, FTX Global, Europe and some regions. In the settings all are checked except in the Transportation.

Well, turn that off for starters!!! And also lower Level of detail radius and Tesselation factor one or two notches. Set Shadow quality and distance lower one or two notches. Turn off dynamic lighting. FTX Vector can be a killer too. And well, yes, the FSLabs 320... that's the heaviest addon around when it comes to performance.

You are using a lot of high fps hitting setting. 4790K @ 4.5 1070 with only 8GB of RAM.

I would be very interested if you tried mine and posted the same test screenshot. I keep 25 fps even with 4xSSAA. You dont need 4xSSAA with 4k so keep that as you have it.

Turn Shadows quality to halfway forgot what that is by name.

Turn off all that railway stuff, Traffic lights and Tunnel exits.

Also use 512 not 1024 and use 4 cloud layers not 5 in ASv4.

Since 90% of my flights are FSL no surprise at my profile name.

Remember P3D v4 is designed for the future not for today. If you bought FSX when it came out just about no PC could run it. 

Well we can run v4 but best to give it some respect.

Hello

I would start by turning Shadows, Scenery complexity and the Water settings down a Notch,  You wont notice a big difference in visuals but will notice a lift in performance  

The post above me Nyxx (David's) settings in Terrain are good solid settings for visuals and performance,  set them this way for Terrain and then experiment with everything else

Also this setting is pretty intense on any system

And reduce Texture resolution to 1m (saves a lot of CPU cycles vs 7 cm).

I removed TEXTURE_SIZE_EXP=10.

I tried to reduce one notch the Level of detail radius and Tesselation, also I set Shadow quality and distance lower one notch. I put FTX Vector OFF.

Surprisingly, no significat change in fps on ground. Is like something bottlenecks it.

 

Regarding the test with 4xSSAA with those settings Nyxx, here they are (ah you edited, will try additional):

4xSSAA, 4K (even if in sim is 1080p), DL ON:

4xSSAA, 4K (even if in sim is 1080p), DL OFF:

Bert,

Since I like nothing more than sharp textures I was amazed at you saying use 1m. I thought as I read it " you're crazy":biggrin:

But I thought I would test it and see how crazy you are! :ohmy:

Well I could not see any differences, Well you can but it's very small. I was surprised is an understatement. 

 

7cm

using less cpu cycles is a win Bert. Thank you, nice find.

I tried all these lower settings, still 20-22 fps on ground and after takeoff.

Reloaded my settings in air, fps jumped from 22 to 28-30fps.

This I do not get it, what bottlenecks it, is more than strange. Something is not consistent...

Delete your config file and your shader 

Start from fresh.

 I will post some FPS for you, want to help if I can?

hi vali, i had problems similar to you, stutters and a general lack of smoothness on a pretty high end system. my solution is to use Simstarter NG, it allows you to set every single parameter 

in the sim (and all activesky parameters) and save them to individual configs ready to run. for example: for night flight in the airbus you could reduce the unneccesary stuff (shadows, trees, reflections, water, less cloud layers and reduced cloud draw distance etc) and the resources freed up will give you more smoothness with dynamic lighting on. 

feel like VFR in a prop plane, lower the things that you don't need for that type of flying and save as a new profile!

create as many customised profiles as you need and away you go.

it also allows you to play around with all the known config performance tweaks and save these to each config.

it really has been a gamechanger for me. i also notice you use DXT clouds, i find with my 1070ti that 32bit is smoother but no idea why!

all the best and good luck.

Its frustrating as I just did a fps test with my setting since I dont fly at night I was bothered about what I would see and also using the big no no SSAAx4

31FPS I wish I could help more :blush: it went down to 25-26 with all VC lights on and Dome at BRT. But you should not have Dome light on when taxiing and taking off.

If you fly near the ground more or fly Orbx you'll notice the difference a lot between 7cm and 1m textures.  Also vector graphics use 7cm - roads coastlines rivers etc

Davids suggestion is a quick and small step you could try that wont effect any of your Add On's,  You will just need to apply your scenery \ graphic settings again to your preference via Prepar3D > Options  after you delete the Prepar3D.cfg file

So Delete the Prepar3D.cfg file and the Shaders folder  (These files will generate again as default when Prepar3D is launched)

Then launch Prepar3D and test.

To locate these files Insure you Tick the box for  Show hidden files, folders and drives in File Explorer Options

I deleted the config and shaders. At first startup after this, with its default config I have 30 fps. With them set as they were, goes to 20-25, panning is OK.

David, are you using Berlin Tegel Professional from Aerosoft? I do have some clouds also. I am using that with these settings:

This is with my initial settings from this post, recorded with OBS to 1080p (this is why there are some stutters) but I was flying at 4K. YT takes some time to get it at 1080p.

Did not why EVGA OSD or Fraps layer did not work, there is only the in-game frame counter.

Cannot see fps on my iPad.

Did you gain any performance in the end tonight?

A few other things I did not say before.

In PMDG and FSL you can change the refresh rate of the VC displays and the pop up 2D ones.

I use a 2nd screen below my main. My zoom level is around 0.8 this means its not drawing all the VC like in your vid. Your zoom level is very wide.

Do you have chaseplane?

I have VC displays set to just 6 fps and pop up that I have on my lower screen set to 12 fps. All this helps fps even in the NG.

Following this with interest.  I must admit, with the OP's GTX 1080 Ti and still less than 30 FPS with P3Dv4.1 something is definitely wonky.

I have basically the exact same setup.  I can manage a consistent 30 FPS (vsync on), with unlimited I can range from 30 up to around 60 in most areas except for DD New York area, Orbx SoCal and the like.  All with PMDG 737.

However, I'm finding that I also get periodic stutters on the ground which I'm finding to be mostly related to Orbx Vector.  You may want to test by disabling that or turning off some features.  You can probably turn down the ASCA cloud quality to minimum.  I don't see a difference in visual quality with that.  In heavy clouds and weather my system certainly takes a beating.

I am on the same platform with a little weaker components and do not have any fps/smoothness issues even with settings a little higher than OP. The main difference seems to be the RAM. I am using 32 GB (@ 3400). As already mentioned 8 GB is probably not enough to push your system to the top level. If you can afford, you should go for 16 or even 32 GB (@ 2800 MHz or higher). I also disable Intel Turbo Max boost 3.0. which give a better usage on all 8 cores. If ITMB is active one core is always at 100% but the other are mostly below 10%.

Not really, tried all recommendations :D Reducing the settings strangely enough gave me not enough gain and the initial settings looks so nice when and where they work.. :D

But with my high settings, PMDG 777 at EDDF Professional, I had in average 30 or above in the video, which is really OK, no stutters (only OBS introduced in the recording).

Yes, I am using Chaseplane. Regarding the displays fps, I checked with FSLabs, 30, 20, 10, 5 not a visible impact on my side.

Well, at 4K and DL...It really pushes strong :)

In the video with PMDG 777, Vector was deactivated. 30+ fps. At EDDT with 777 I have also around 30fps. But FSLabs A320 at Berlin Tegel Professional, 2 add-ons which are not so well optimized in terms of fps... 20. Same for EGLL. I think I have to live with that for now. This is also one of the many reasons I love the Dash 8 :)

I am using 32 GB @3200 CL14 from G.Skill. And the EVGA 1080TI FTW3 has 11GB, with TEXTURE_SIZE_EXP=10 it goes over 8GB usage of VRAM.

I spent many hours trying to optimize my settings in P3D v4.1, at Aerosoft's Heathrow, ORBX England and FSL A320. To my surprise, even with nearly all settings maxed out, there is a single setting that makes all the difference: Scenery Complexity. Set this to Sparse and suddenly fps took a huge step up. Note that my autogen distance is on medium and the autogen sliders at Extremely Dense.

Try that.. In heavy sceneries like EGLL, I think is the only solution. Not sure how much we lose visually..

what does "Scenery Complexity" control exactly?  What do you lose out on with it turned down?

I had the same question..after some googling I found that it controls custom objects (not generic autogen),  for example landmark buildings. I will have to do comparisons with 'Dense' for example to spot the differences. In large cities like London, probably ORBX has placed many custom objects that should be the reason of the bad performance. If its just that, then I'm happy. I'd be interested to see if you and others, can also see that dramatic fps improvement as I do.
