Periodic Massive FPS Drops in Multiplayer

[Disease_Marketer]

As the title says, I've been having a serious problem with FPS drops on my relatively new computer.  When nothing's going on I'm staying easy on 60 fps but in big fights (mainly in multiplayer) I start seeing drops all the way down to 10-15 fps.  These happen for maybe five seconds, then they go away, every 30 seconds to a minute.

 

My computer:  AMD FX-8350 (8 core, 4.0ghz), GTX 660 (3gb), 8gb DDR3 RAM, 1920x1080.  

 

The stutters occur at all graphics levels which leads me toward a CPU problem but I feel like my CPU should be fine for a game like this and I don't remember it happening when I first got BoS.  

Things I've tried (Get ready, it's a laundry list):

Checked temperature, temps are all fine

Moved my computer to ensure temps are fine, temps are even better, better than they've ever been

Checked resource usage, BoS averages less than 20% CPU usage

Defragmented hard drive, cleaned out temporary files and registry to eliminate hard drive write problems

Went ahead and reformatted my computer completely, ruling out any software issues on my end. I was overdue anyway

Unparked CPU cores

Tried to find terrain.ini to unify terrain LOD so it's not constantly changing but I don't have a terrain.ini file (I'm on Steam)

Went through just about every combination of graphics settings as well as FPS limiting

 

Limiting FPS to 30 helps inasmuch as it makes the stutters less dramatic but it's very frustrating to play this at low settings and 30 fps on a computer that runs everything else just fine on high, and still have problems.

 

I've gone through just about everything on my end short of getting a new CPU (that's not an option right now, especially not for one game) and I don't know what else to try.  If there were any other good flight sims with active multiplayer I would've said fuck it and moved on, but there aren't.  I don't know what else to do aside from asking on the forum if anybody else has had this problem.

I was just wondering if its a network setting of some sort

[Disease_Marketer]

Like what?  I haven't done anything with network settings and I don't really know where to look on that side.

 

Again, the last obvious possibility I can think of is that my CPU is choking on the flight models in big fights.  Does anybody with a similar CPU have anything to weigh in on that front?  I don't /think/ it should be a problem and I don't remember having this problem when I first got the game around Christmas.

I seem to be past the edit time so sorry about the doublepost.  I found the problem. T here's some kind of AMD utility setting called turbo core that was overclocking me by .1mhz per core, then Windows throttled htem to save power.  Disabling all that seems to have solved it.

This issue with the later generation AMD CPU has been a big problem with many CPU intensive sims/games, a strange problem because it is actually meant to increase performance...but anyway it seems to have taken a year or so for this problem to reach a mainstream audience as a solution

 

Glad you got it sorted
