Super Slow FPS But Have A Loaded PC

Recommended Posts

Dont have Ortho but have lots of ORBX terrain and other addon airports and PMDG aircraft Im using. I have a PC built around an Intel i7 7700K, not overclocking currently, have a GTX 1080 TI Rog Strix with 11 gig of ram, 128 gig of onboard ram. My display settings are on the medium side. P3D 4.2 Add ons, like EZCam, GTX, the REX 3d Clouds and Active Sky. Im not using full screen res. I think its like 2560x1440 . Texture - Ultra, Texture Filtering NONE, FXAA 2X, AA: 4X. Vsync ON, To me it seems like these settings are standard from what I've been reading and seeing on here and on some videos. But I still am having these issues. Really bumming me out. I definitely cant go full resolution monitor wise or it creeps like a snail... Seems addon airports are worse, even UK2002 like Heathrow are dragging which are supposed to be fairly low in FPS strain. Help me guys !! Ive been flying transatlantic with the PMDG 747-8 and the 777 and been enjoying it so much but coming in for a landing at 15 FPS sucks !

There's a whole lot of relevant detail missing here...most of the most important performance-sensitive settings aren't really mentioned.

Ortho?  In P3D? 

A 7700K running at stock speed (4.2 GHz on all cores) is 19% slower than the one I had running at 5.0 GHz--that's a lot of performance left on the table.

AA: 4X?  Is that 4xMSAA or 4xSSAA?  Set in sim or using an external utility like NVI?  Are dynamic lights enabled?  Cloud texture sizes?  Autogen density and LOD settings?  Traffic density?  Frame rate target?  No AF at all?  Running full ORBX regional scenery as well as the add-on airports? 

I think you need to do a fair bit more research and experimentation w/r/t performance tuning.  Heathrow at 15fps on a 4.2GHz quad-core is approximately what I'd expect without making some compromises.

Regards

These are my current settings for my card and P3D. I tested my card with several FPS programs to get the best performance without crashing, so its slightly overclocked. Never looked into overclocking my CPU. Yes dynamic lights are enabled. Frame rate target 60. Im running the ORBX add ons all for north america and UK as far as scenery goes, no ORBX airports. But plenty of airports from other 3rd party developers. I havent looked at cloud texture sizes but just bought REX Environment so I am going to revisit. https://ibb.co/z4JwZ9W Cant sort out how to upload a photo but heres a link to my screen shot.

Well, first off all I'd suggest you ditch the internal frame rate lock. It's not a conventional lock, it messes with how much processing is dedicated to various tasks and can severely impact performance. Try using RTSS or Nvidia Inspector.

Yeah the internal frame lock alone will cost you about 15 FPS bc it sets FFTF too high.  Set that to unlimited.

Also make sure you don’t have any static aircraft turned on from U.K.2000, those perform awful from my testing. 

Set building autogen density to Normal and LOD radius to high when flying into EGLL.

Also, EGLL is the most unique FPS killer in the sim that I know of. I can take off from default Chicago O’hare and even LAX with 55 FPS and those same setting magically get me 34 FPS at EGLL.

The settings visible in your screenshot are not what you posted...you are running 2xMSAA, not 4X, and FXAA is off, not on.  No idea about the other settings not on that page.

ORBX regional scenery is pretty heavy on performance.  LHR is also a known performance challenge, especially if you have traffic levels set much above minimal.  Autogen density and LOD remain unaddressed.

I have no idea what you mean about not being able to use "full screen resolution."  Is your monitor's native resolution something other than the 2560x1600 res you have set?

Sorry Im not the best at this ! I did that from memory while at work, memory is not as good as I thought. I will look into the autogen density, at the moment other than GTX I have no P3D based traffic going or objects. I overclocked to 5GHZ last night. Still slow as molasses leaving EGLL until I got a couple miles away from the airport. I also only have 32 gig of ram but am not sure if that's really an issue. Are those settings I posted at all good for a better performance ?

I actually upgraded to 4.5 last night, do you mean the slider? Should be unlimited?

My resolution for my screen is 3840X2160 its a 28 inch 4K ASUS MG28UQ but I definitely cannot use it with FPS this low, so Im back to 2560X1600.

Is your monitor capable of a 30 hz refresh rate?

From a cursory look, that monitor is a free-Sync monitor that not only should be able to work at 30Hz, but it might also work with nVidia G-Sync using current drivers.

Also, a 28" 4K monitor has a high-enough pixel density that it should require no AA at all.  A 1080Ti should be capable of driving that monitor at 4K with no AA without any impact to frame rates.

If you have a 30hz-capable monitor, then I'd recommend setting your refresh to 30 hz, vsync=on, and the in-sim framelock=unlimited.

After that, if you are concerned about Heathrow (who isn't), I recommend setting up and saving a P3D configuration profile (mine is called "London").  It has autogen radius to Medium, autogen buildings at normal, and autogen veg at dense.

With your cpu (now at high 4's or 5.0 ghz, I hope), I'd recommend autogen radius medium, autogen buildings at sparse, and autogen veg at normal.  Both special effects sliders to zero.  AI cars to no higher than 7% (or zero, preferably).   Now you test.  Start low and build up your settings...not the other way around.

Man you guys have been more than helpful. Im pretty sure I am refreshing at 30. Should I keep my resolution set the same at 2560X1600? Seems all the airports, KSDF, KLAX, any add on I have seems to just eat it up, turning my head in the cockpit takes like 2-3 seconds. I connected the larger HDMI cable that came with my screen, believe its like the HDMIx or something cable that clips into my graphics card, I remember the refresh rate changing for the better once I did that. 

 

Im clocking at 5 now ill see what happens !

Hmm I´m quite happy with 4.5 HF1 Performance. 

Using a 9900X @ 4,6 Ghz with 32 GB RAM and a GTX 2080TI , Windows on a 960 PRO M2 and P3D on a 970 PRO M2. Montior is 34" Acer Predator 4K with G-Sync.

Frames Locked Internally at 31 FPS,  30 hz Refresh for the Monitor.

For sure in ORBX GB South with Aerosoft EGLL  i only have between 12-15 FPS with PMDG and FSL but that`s because i have very high settings. 

I also use AIG AI Traffic so also the sky and the airport is very heavy crowded with AI Planes.

But i love to see all the thousands of Autogen Buildings and Trees while i takeoff, so i accept the "performance" hit, and it still feels "more or less" fluid to me.

I have UK2002 version of EGLL and its just un flyable which seems nuts to me. But my settings arent that crazy at all and i have no traffic add ons. Frame lock as in you use the slider option in P3D or is frame lock a feature of the GTX? I dont think i use much autogen at all i have to go look. Im trying to figure out now what it really is so i may have to uninstall some things, or disable them at least to test it out.

Can I ask how to i engage free sync or g sync for my monitor ? 

 

3840x2160 @60Hz with DisplayPort1.2/ HDMI (v2.0), 3840x2160 @30Hz with HDMI (v1.4)
**Adaptive-Sync (FreeSync) technology supported within 40~60Hz for DP only
***USB3.0 ports with Power charge BC1.2

 

This is listed on the manufacturer website, im currently using the displayport cabe so i am guessing im at 60hz refresh? And the freesync works within the HDMI 2.0 or displayport but not the regular HDMI. Am I better off enabling freesync instead of sticking to just 30 or 60 ?

I use the P3D internal slider and set it to 31 FPS.  I tested with Locked and Unlocked and for me the difference was "minimal" 

 

@broncoblair I have a setting in my graphics card menu, but i use g-sync.

Setting FPS unlimited on its own is asking your PC to throw out as many FSP as possible all the time. Bad. You can set FPS limited within the sim and simply add an FFTF of 0.01 to make P3D just run the same as if you had set unlimited. It's much better to have your FPS locked or "locked" through VS. Than just unlimited on its own.

Be careful with RTSS if you use pop up 2D panels. I tied using it and it hafted my fps that RRTS had locked. But if you don't use 2D pop-ups it should work well.

I flow out of EGLL simwings yesterday in the FSLA320 and my locked fps never dropped below the 26 set within P3D. 

If you have your PC overclocked to 5, it seems you have some big problem some were.

Its a huge problem as setting up a PC to run P3D well is down to hardware, then setting within the sim and what tweaks to fine tune it. A mind field really. Reading your reports sound you have a fundamental problem with your PC or the install of P3D. Run some test on your PC to see what results they come up with.

What you want to do is try and VSync @ 30 Hz.

This will automatically limit the frame rate to ~30 fps as it will tie in with the Monitor Hz rate. It'll wobble about because that is the nature of the vsync, however it will be a very smooth experience, provided there is enough headroom to be able to maintain the 30 fps.

This will also reduce the GPU load meaning there is a wider configuration option to tune GPU use so as to not max out at 100%, noting 100% is GPU overload and will kill frame rates back to a stuttery mess.

So set the following.

  • Monitor screen mode @ 30 Hz.
  • In P3D Vsync and Triple Buffering on.
  • P3D frame rate to unlimited.

If you cannot reach 30 FPS with the above configured it means you've pretty much hit the ceiling of P3D CPU perfomance (3D building handling in P3D is somewhat lacking in performance - hopefully it is an item next on the LM list of things to improve), however with a 5 Ghz overclock and 2080Ti (which you can also overclock) you should be pretty good.

Note complex aircraft and tubeliners do suck the fps out of P3D.

Some hints are to try reducing the traffic (just turn it all off for starters and see how much the FPS inproves), also try reducing the scenery draw distance as the less distance it has to draw the better the FPS.

I recommend using a tool to monitor CPU and GPU use to get a feel of what P3D settings values affect the CPU / GPU use, and use a consistant senario for testing - e.g. your fav airport (where good FPS can be achived).

You can then create and save profiles for different types of flying and can swap on the fly so to speak.

Here is a link to a vid I've made @ a 30 Hz screen mode, the vid includes P3D settings to help give an idea on the type of perfomance and settings used for for the given scenario.

So regarding my CPU being clocked at 5, i monitored temps while flying they were in the 70's. I just did a stress test and they jumped up to 95-99 so i stopped immediately. Seems I am going to have to look into a new cooler or have Corsair replace my current cooler. It is supposed to be a liquid cooled single radiator but it doesnt even seem to be keeping temps low at my regular 4.2ghz. I tested stock at 4.2 under a stress test and my temps were reaching 79.

Ahh, yes large temp increases, just what I found when I overclocked my Ryzen from the default 3.2 GHz to it's curent 4.1 GHz.

I did two things to reduce temp to maintainable postions.

1), Disable SMT ( Simultaneous multi-threading ) - HyperThreading in the Intel world. This reduced the 16 virtual cores to the 8 physical cores and made for quite a large temp drop and also had the effect of being more stable e.g. I was able to go from 3.9 Ghz to 4.1 Ghz with stability. Performance was essentually improved with disabling of SMT.

2), Replace the cooler. The Ryzen came with its own Wrath cooler which was small but perfectly suited to the default clock speeds. I now have one of these beasts installed and it is great, cools very well and is extremely quiet. IMHO worth every cent.

I can thoroughly recommend the Noctua NH-D15. It is a beast, just make sure you have enough room in your PC case!

@broncoblair, you have a UHD monitor which the 1080Ti can handle with ease. Whatever you do do not run it at anything other than its native resolution.

Not only will you seriously compromise the picture quality the fps you are saving is minimal.

Get the SimWings Heathrow Professional version from Aerosoft optimised for 64-bit. I had the earlier Heathrow Xtended and apart from the awful ground textures the Pro version gives me an extra 5fps.

I have the AIG Ai package and with over 300 Ai in an 80nm bubble around EGLL my frame rates still hover around 20.
