Regarding gradual performance degradation while flying

[335th_GRAthos]

I noticed something, maybe it is, maybe it is not the reason but I post it to hear opinions.

Some people complained about gradual degradation of fps while flying over longer periods of time.

I fly SLI nowadays, 3 monitors, usually at nice 70fps but sometimes I get only 30-35 on some servers.
I noticed that 30-35fps I have only when the VRAM starts been completely full.
In the past I used GPU-Z to monitor my GPU, now I use NVIDIA Inspector 1.9.5.5. (because I use it to create my SLI settings anyway) and constantly monitor the VRAM of my GPUs.

While flying I noticed that my VRAM slowly gets full while it rarely empties.
As a concequence, the moment your VRAM will be used up, then you will most probably start experiencing the performance loss.

I do not know whether landing and re-flying (create new plane) solves the problem, I have not tested it yet.

But it may help some better understand the problem.

My screen (3840x desktop with CoD windowed 3072x) the GPU monitoring is on the far right (REPKA#1 server Channel (full real)).


EDIT: Maybe I was too fast in my assumption, on the REPKA#2 server Channel with icons I see that the fps is half and the GPUs are working much less
@Ataros: What is the difference between REPKA#1 and REPKA#2 in terms of objects? I see a lot more objects on the REPKA#2 Probably this makes the difference

BETA Patch v 1.03.15527 (Has happened in all versions of the game so far)

There are no issues like this using a single card. Trouble shooting has gone as far as using a clean install of windows.

I have the same issue with crossfire, the game starts out running great and after a while the frames get capped and GPU, CPU usage decreases. Paging file and system RAM start to fill up as this goes on. The only difference for me is that online frame rate stays average of 10fps with crossfire enabled and I have never been able to get decent frame rate online with crossfire on.

I am using a single 1920x1080 screen during testing. Starts at 80FPS average, after red line drops to 10FPS average. Regardless of in game video settings it eventually drops.
