Fps Drop When Playing Online

[6./JG5_Boelie]

Hey everyone, I'm currently having this issue where I get an FPS of about 30-40 while playing offline. Yet, when I go on a server, I can't get my FPS above 20 at all and stays at that level somewhat steadily. It's never been great, but since the last update it's even worse.

 

Just so you know:

Vsync off

High settings

AA set to 4

All driver settings: depend on application or off.

 

My system:

Intel Core i5-3350P @ 3.1 GHz

Radeon HD 7950

8 GB RAM

Just installed newest drivers: 14.501.1003 

 

A friend of mine has nearly the same setup, yet he's getting a higher FPS, even on ultra settings.

 

Can anyone provide me with some suggestions? Thanks!

A small update, whenever I look at the sky or the seat on my plane, so no ground is visible at all, the fps 40. As soon as I get a bit of ground in the mix it starts to drop and the more ground I se, the lower it gets up until 20 fps... I'm clueless, as my system should run this a lot more smoothly than it is...

Is your game on another hard drive?

I suggest you run this to start with and see if your card and drivers are working correctly.

Same here!

MotherBoard: Asus M5A97 R2.0
Processor: AMD FX8350 Vishera
Mem: 2x 4GB RAM Kingston HyperX RED
VGA: Nvidia GTX 970 G1 Gaming
SSD: PNY 120GB
Water Cooler: Cooler Master Seidon 120V

The game is running from SSD

This all looks perfect to me, so I dare say this is not what's going wrong?

[6./ZG26_Emil]

I'd try uninstalling the game and re installing it personally.

[6./JG5_Boelie]

I tried, no success of course

[6./JG5_Boelie]

Upon further testing it seems that when in balanced, high or ultra, it all works well up in the sky. Yet, as soon as I get close to the ground, my fps starts dropping from 35 to 20. This is worst when I'm looking at an airfield and I see my fps drop to about 18. 

 

My guess would be that there is something in the ground textures that is eating up frames as the closer I get to the ground, the worse it gets. I didn't have this before the patch, though I did notice a difference between high and low altitudes back then. 

 

Still no solution, so if there's anyone with suggestions, I'm all ears!

Is this always on a specific server?

 

If there are a ton of ground objects to be rendered around the airfield due to a custom mission, that might make a difference.

You might try flying way out into the arctic wasteland and then dive down and compare.

The team seems to have pushed the boundaries of dx9 pretty far with the stunning visuals and atmosphere in general in this sim. Hopefully in some distant future they will be able to patch this amazing piece of software to dx12 and make 1000's of AI interact on the map (If dx12 is as good as the presentations that have been shown by Nvidia.)

[6./JG5_Boelie]

I've tried it both near ground objects as well as in the middle of nowhere. Admittedly, it's a tad worse when I'm near ground objects.

 

Dx12 sounds good, but that won't help me on the short run. If 1C/777 can't provide a resolution now, then myself and some other people would have to wait and sit it out. Would be a real pity of course....

Also, it's on any server so far.

After using MSI afterburner for a while, I noticed that IL2 BOS doesn't use my graphics card (GPU usage) to the fullest extent. The picture above is at high, I've also tried it with ultra and VSYNC on, only a minor difference. When using 3DMark, this goes up to 98% and stays there. 

 

To me this looks like IL2BoS isn't utilizing my graphics card to the fullest extent, therefore decreasing the FPS output dramatically.

 

So, I would really like a statement from 1C Studios, if they're aware of this and if they're working on it. Of course, this can be done via PM too.

S!

 

My guess is still that the BoS is bottlenecked by your CPU. If you fly at high altitudes (7000m) in Quickmissions you should get a higher GPU usage, cause the CPU has less stuff to do there. Keep in mind that the CPU plays a big part in the progress to get high FPS.

 

Just to make sure, does you friend by any chance has another CPU or did he overclock it?

So, I've used CPU-z, intel software, anything I could find. It seems I either have the newest driver or something is wrong with that intel utility. Please, see my CPU stats below. I started at 7k and worked my way down to a fight of 1 on 1. 

 

The thing that stands out most, aside from the low FPS, is that my memory usage of my card is very low. It's a 3 GB card, yet it seems that the max it reached was 800 MB.

 

Any clues or suggestions on how I can filter this issue out any further?

 

[Zettman]

S!

 

Interesting would be your GPU usage compared to FPS from high to low altitude. The GPU usage should be increasing with higher altitudes, so should your FPS.

Hi Zettman,

 

This is the one where I start at 7k, stay there a while, slowly work my way down and initiate in combat. As you can see, my GPU usage remains low, as well as my framerate. 

I had a few buddies try it as well, they both reported a way more substantial use of their GPU. Both have ATI cards, one older and one newer.

 

Anything you can see in this? The thing is, with other games it works perfectly, higher GPU% and FPS. 3DMark gets it done as well, to a full 98%. Any other questions, please ask.

Sorry for the late reply. Honestly I was expecting something different. I'm not sure why your FPS and GPU usage don't change with altitude. I will try to do some testing the next week.

 

Zettman

[6./JG5_Boelie]

Thanks dude!

[Zettman]

S!

 

Ok here are the test I made.

 

First round, climbing from 6000m to 7000m and going down from there at about 400km/h until ground level. All tests done in Quick Missions.

 

First screen with 3-way SLI (all 3 GPU show the same usage)

 

 

 

 

 

 

 Second screen with SLI turned off (only one GPU has usage bigger 0%)

 

 

 

The pictures show that what I was exspecting. GPU usage is high at the beginning and goes down a bit at groundlevel. Also what ever thread is running on CPU3, seems to be the rendering thread, cause it has the highest overall usage and goes up when I go closer to the ground.

Honestly I was exspecting something similar with your system, but your screens don't show it. So I have no idea what it could be.

 

Another thing I noticed is, that while using only one GPU, I got better overall FPS. About 80 FPS with one GPU at groundlevel vs 60 FPS with 3-way SLI. Will post this somewhere as a bugreport, cause it seems to me we got negative GPU scaling all over again.

I did a second test where I dived at a higher speed and directly from 6000m down to groundlevel.

 

First screen with 3-way SLI

 

 

 

Second screen without SLI

 

 

 

They both show the same results. The GPU usage going down at lower altitudes is a bit easier to see in them. Still getting higher FPS with only one GPU. So it seems that negative GPU scaling is really there.

 

EDIT: Just noticed we are already in the bug report section, should I still write a PM to a developer about this issue?

You may get around 70fps around with only two cards enabled near the ground? Curious to know.

S!

 

They are in a waterloop, so it is not that easy to switch to 2-way SLI. It is either all 3 or off (just one). I will try if I can enable two of them in the Nvidia Inspector later this week.

 

Zettman

[6./JG5_Boelie]

Well, it seems to be fixed for me... Unfortunately, it happened right at the time of the update, so I'm not sure.

 

I checked my power saving options in W7, it seems PCI express power saving was set to off, I set it to balanced power savings and that seemed to increase it.

We then had the update, before I got test it more thorougly. Now, I'm running at 40-60 fps, even on the ground. I'm now playing on Ultra and Vsync on. Whatever was done, it did the trick.

 

Zettman, thanks so much for your time and effort. Truly much appreciated!

Zettman,

I tested a bit more and found what your suggesting to be true for me as well, SLI taxes the CPU too much for me.  Single GPU seems to work better, DX9 doesn't like SLI all that much for me. Will be moving to 980 soon...
