Overall Performance in P3D2.5 after recent Hotfix

Recommended Posts

Folks,

 

I'm struggling with major FPS problems after recent patch. With Airbus extended and FT EKCH, no AI, no ORBX, I'm barely getting 23FPS. P3D is set to 1024 textures, no Autogen,

 

My PC Specs are i7-2700k (no OC), 8GB RAM, GTX780, Win7 Pro.

 

Your advises would be much appreciated.

EXACTLY THE SAME FEATURES, EXACTLY THE SYSTEM OPERATING, AND THE SAME RESOLUTION GRAPHICS,

WITH A DIFFERENCE THAT I HAVE INSTALLED THE ORBX SCENERY.

 

MNY FPS ONLY BETWEEN 9 AND 12

HI, i7 4790k, GTX 970, 16 gb ram, 4K monitor, Horizon GenerationX photo scenery, UK2000 airports with Real Air Turbine Duke for Prepar3d, average 50 fps. No tweaks, as it comes. No complaints!

Whenever you have problems with fps that you do not like, you should return your P3D settings to the default.  Leave the scenery sliders at the default and in the other pages, modify based on your preferences.  I turned on AI, HDR, and shadows.  The Airbus may not be fps friendly.  I know, for instance, the PMDG 777 VC is a fps killer but everything else is okay if in wingview our outside view.  Autogen needs to be turned off if you are having problems with fps.  If you're flight the framerate friendly aircraft - Real Air Turbine Duke - then you can turn autogen back on.  But not with Airbus and PMDG 777.

Do these two things before any more testing/troubleshooting:

 

1. Restore the Prepar3d.cfg to default by either selecting default in the Settings-Graphics page, or even better delete the Prepar3d.cfg and let it rebuild a new one from scratch.

 

2. Delete the files in the shaders folder located in your \users\username*\appdata\local\Lockheed martin\prepar3d v2\shaders\ directory and let it rebuild the shaders from scratch.

I am surprised about this statement. On my P3Dv2.5 system the new P3D Turbine Duke is not at all framerate friendly!

Interesting. For me the Turbine Duke is about the same, performance-wise as the Twotter, the Milviz B-55 and the A2A GA planes. It's easily flyable with Rob A.'s settings on my rig.

 

Only the NGX and the 777 require me to back off on some sliders to maintain 20-30 fps

Yikes!  For me it is just as frame rate friendly as the Carenado aircraft included with P3D.  Disclaimer:  my P3D settings are not maxed out but set to the default as indicated in many other posts here in the P3D Forum.

23fps is perfectly acceptable in P3D *IF* it's smooth. Your main issue is your CPU needs to overclocked. You are not going to get much better at stock speeds with that CPU.

 

If you can get 23 smooth and stutter free, turn of the FPS counter and be happy.

When you say Airbus extended, do you mean the original, or the new A318/319 or 320/321 with the WXR radar? If the latter Some people report severe performance with the WXR active. The problem is by default the weather background scan is on whether you are using the weather radar or not. To fix this you need to add the following lines to the AB_ND_GDI.ini file under the aerosoft\airbus sub folder in your documents folder. Then the only time you would see this performance decrease would be if you turn the WXR on.

Yes, it's new A3X Bundle that I purchased recently on simmarket.

 

23 FPS - it's static measurement after 10-15 seconds of non-activity. Once I start head movements, things tend to get worse, i.e. around 10-12 FPS.  Add AI Traffic and kaboom. 

 

I think I'm going with full reinstall as I have a feeling that something was broken during patch's update.

 

Also, I remember it was a discussion several day ago about the different version of Simconnect? What was the final verdict - can all of them live together OR only the recent one (with "9" at the end) should be left. 

 

Thanks again for your help and attention to this topic.

 

 

PS. On a positive note I must say that VAS management truly improved. Stable figures despite my stress-tests.

Tom's suggestion with regard to WXBackgroundScan definitely improves performance.

Sorry for all this buzz, folks.

 

Somehow latest fix turned ON Triple Buff + VSync. Since I don't use Aero for aesthetical reasons, the impact was the immediate drop in FPS around 30-40%. Turned off TB/VS and bingo - got my FPS at normal 20-25 level in complex airports as before.

I am getting 25 fps easily with the 737 ngx...but it stutters a lot..kills the immersion

It's one of the most frame rate friendly addons in v2.5 for me.....  

 

Just goes to show how inconsistant the performance is, that we each see with P3D!      

 

The T-Duke used to be a heavy hitter for me in FSX, but in P3D2.5 it's super easy on frames at this end.     And the Aerosoft Airbuses ; insanely good performance.

 

However, the A2A 182 and Cherokee ------------>  much heavier performance (lower frames) in P3D2.5, than I used to see in FSX.

Too generalist a statement.    Not true when using TrackIR

Now I am flabbergasted again :)

The A2A is the most easy on the frame rates of all my planes (except the default Maule) in P3D!

And the aircraft I fly the most, it has super smooth flying.

If you have 25 fps something is wrong with your setup. It is so smooth beyond anything i have ever seen

The stuttering is in particular strong when looking to the side from the cockpit. No stutter at all with your setup? In fsx that same situation is super smooth.

Any tips on how to get rid of the stutters is appreciated

So what does rebuilding the cfg file and deleting the contents in the shaders folder do?

Have a look at this one though it is 12942 but and its the same in the NGX

Perhaps for you but I always use TIR and have absolutely no issues. If I go below 20fps, it becomes iffy but anything over 20 and it's smooth WITH TrackIR.
