Low frame rate

Low frame rates

 

I forgot to mention that I still have all the tree's, bushes, grass, building's, etc, with the sliders at their lowest settings, and all the other settings are on low.

 

The eye candy is still there no matter what the settings are and as I mentioned in the previous post, even though city traffic is off, it still shows up anyway.

 

The quality of the graphics is exactly the same no matter what the settings are

?? What Fab says, once you choose your settings, you have to restart DCS to apply them. And don't forget to hit left alt+enter to be in fullscreen mode.

Use the attachment below if you wish to use the older 1.5.2 visibility values (unpack to Config\terrain folder in DCS)

 

Worked a treat!!

Many thanks for this Mustang!!:thumbup:

Hello again everyone,

 

Got some doubt regarding "Game Performance" which I believe suits at this thread, instead of openning a new one.

 

After playing FC3; version 1.5.2.xxx; single player; Caucasus scenario; for some 20 minutes, regarding my GPU ( GeForce GTX 770 oc 2 GB ) my HW monitor software only indicates the following maximum values:

 

Utilizations :

GPU - 99 %

Frame Buffer - 44 %

Vídeo Engine - 0 %

Bus Interface - 10 %

 

As I really am very noob regarding a lot of this - shouldn't the last 3 values be having more utilization, in order to get the most of my hardware when playing ?

 

Thank you.

[Kuky]

I don't know about Frame Buffer and have no idea what Video Engine does (maybe something to do with rendering a video? Anyway, no idea) but last one is PCI-e bus interface BW and you don't want that one to be fully utilized. It is the limit for how much data can go through from the hardware to motherboard and in most hardware the buss should always be higher (or at least equal to) amount of data the hardware can process.

[Hadwell]

the frame buffer is the memory on the videocard that holds the finished images that get sent to the monitor after the gpu has rendered them...

[Top Jockey]

Hello, thank you both for the clarifications on my doubts.

 

As my GPU is not "top of the line" anymore (still it's less than an year old and was pretty damn expensive) I want to make sure I get the most of it in DCS; reasonable mixture of "eye candy" / FPS performance.

 

So it seams everything is normal.

 

Interesting fact, although in DCS FC3 the Vídeo Engine isn't used, it is in games like GTA IV.

Since i upgraded to Win 10 i got much, much lower FPS. Around 5-20. On the exact same hardware in Win 7 i got 30-60 FPS. I have made sure there is no hardware bottlenecks, this is what i've done.

 

• CPU is not getting maxed out, its a even 20 % or so spread out on all 4 cores.
  
• RAM is not getting maxed out, DCS is using circa 4-5 GB of my 16 GB of DDR 3 ram.
  
• SSD is not under heavy load, shouldnt affect FPS but worth mentioning.
  
• Uninstalled and reinstalled the video card drivers with no improvement.
  
• Deleted everything in the saved games / DCS folder to remove any old config problems.
  
• My GPU is not rendering any other screen or game, my frame rates are perfectly fine in numerous other games that are high performance.
  

 

Anybody got any clue? I wanna fly :(

[BIGNEWY]

check your power management for your gpu, make sure its not using any adaptive scheme or power saving

I have the same problem, the game doesn't use the hardware at full, only 40 to 50% CPU, 5 GB of RAM, and the GPU stays at 30-35% and I have FPS drops below 60.

CPU % is Linear and Relative depending on how many cores/threads you have.

 

DCS Uses 2 Threads, one for the simulation, 1 for sound.

[Corbett1403]

Very strange

[Bucic]

I've gone back and forth between 1.5.2 and 1.5.3 several times already and the difference in performance is abysmal. I can't believe that none in ED nor the beta testers team doesn't have the hardware combination that makes this performance problem so obvious (as it seems it isn't happening for everybody)

 

1.5.2: you look at a city and keep flying happily.

1.5.3: you look at a city and fps drops to unplayable levels.

:/

Could you please verify that it's triggered by cities and not trees and shadows?

It's been addressed in other topics but the thing here is that in 1.5.3 the visibility ranges changed so that they match DCS 2.0. In other words, if you had the visibility range set to HIGH in 1.5.2, in 1.5.3 you should set it to MEDIUM or even LOW to have the same distances to be rendered.

I was talking about cores, the max CPU usage per core is around 60%. Never exceeds 5GB of ram and the GPU usage keeps at 30% 35%

 

I have an I7 2600K, 8GB RAM, GTX 980.

So, something is wrong with the game. It works but it should work a lot better.

This is not the cause. When on all low settings, HDR and shadows etc off as reported earlier there's an average of 50fps drop in performance.

no, not really... you've got a very old CPU/ Mobo, bare minimum RAM and trying to pump it through a very new VGA, which isn't able to run at its full potential

 

Give it some consideration, perhaps?

I also have a very old CPU but it can handle DCS 1.5.3 pretty well. Of course, high terrain, flat shadows, medium visibility range, HDR off and the fps will stay well above 40 over the cities, in dogfights.

[Bucic]

A plea to all.

Please state your performance: before, after 1.5.3 and after 1.5.3 on LOW visibility setting. Plus a scenario. Otherwise all we're going to see is "your <component> is subpar."

Yes, its old, still the cpu usage doesn't exceed 60% per core

Yes I have 8GB, never exceeds 5GB usage.

 

So... if I had FPS drop with my CPU at 100% and my memory usage was at 8GB, I know for sure its my problem and would upgrade my hardware.

 

I'm not saying the game works bad, it just it should work a lot better.

Considering you may not overclock that CPU you have 3.4-3.8GHz which is basically enough to have an enjoyable gameplay, as I know from myself. So sometging must have happened to the settings in DCS or elsewhere to lower the achievable fps.

 

Have you ever tried overclocking that thing ? It may run well above 4.5GHz and will elimate any need for a currently available Intel CPU imho. Depending on how much you know and dare this can be very rewarding or better a thing to leave alone. Mine runs fine between 4.8 and 5GHz, a 2600k....:)

 

I would honestly consider more RAM....and maybe a SSD if you dont have one yet.

Both is known to help speed up DCS and avoid many common problems.

[Windsortheater]

I have an issue in 2.0 and 1.5.3 where I get big drops in FPS only when zoomed in on a city center.

 

Even at very low altitudes when in normal zoom I get 60FPS locked (frame capped) no matter what. I can pan with trackIR rapidly, down the stip in vegas or buzzing a city in the Caucauses at very low altitude I get 60fps. If I zoom in on a city area however that changes... frames will drop 20-30% (even when sim is paused).

 

Just for kicks I dropped to LOW preset and I get the same frame drop only when zooming in on a city / populated area.

 

i7 4.2Ghz Nvidia 970

 

60FPS locked performance using custom settings (not a preset), but it's probably between Medium and High.

 

I can't for the life of me find the 'setting' that is controlling zoomed city performance... looking for suggestions.

SkateZilla gave you an answer why your CPU doesn't get 100% utilization. Why you don't see 1 core 100% and others less is because OS balances out the load, even if 1 thread runs on 1 core and application like DCS is not multi threaded (with exception of sound engine, which as mentioned runs on second thread).

 

So 60% utilization of your CPU is normal.

[Nealius]

Quick question: Are shadows driven primarily by video card? I noticed I go from 60fps on Flat Shadows to 35-36fps with Low shadows. Wondering what the weak link is. (AMD Phenom 3.6GHz, HD7850 2GB, 8GB RAM)
