FPS stutters AMD CPU

[PhantomRacer]

Hi All, just want to share my recent experience with some FPS stutters and solving the problem in the hopes it helps other people out.  First a bit of history, I'm an old PC and sim gamer who has recently come back, I build a new rig recently and chose an AMD 8350 as the CPU.  The full rig is:

 

AMD FX8350

MSI R9 390

Gigabit 990X motherboard

Toshiba SSD

16GB RAM

 

Anyway I've been playing BOS on Ultra without any issue for the last few months, FPS air 40-60, FPS ground 30-45.  That was until the last update, since then I've been having a drop in FPS every 60-120 seconds, depending on how many other planes were around.  The FPS would drop to 8-10 for a second and then return, which was making the game unplayable.  So I tried many different solutions:

 

reinstall DirectX

reinstall BOS

Process lasso

turning off power management

Dropping to low settings on the graphics settings (which made no difference to FPS at all)

 

GPU wasn't loaded, the fans aren't even on when playing BOS.  The CPU doesn't look loaded either, no cores are maxed out while playing but for some reason the 8350 just couldn't spit out the physics calculations for the game fast enough, I'm guessing it's the physics calculations.

 

So in the end I tried an overclock, just using the Gigabit software provided with the motherboard, which fixed the problem.  I've overclocked to 4.5 GHz, it's actually 4.3 GHz but the AMD CPU have a 0.2 turbo feature so it can go to 4.5 GHz if needed.  Now I don't like overclocking but if your having the same issue as I have it may fix your problem.

 

My advice is avoid the AMD CPUs for this game at the moment.  I don't have any issues with anything else I play, normally 100+ FPS.  BOS just doesn't seem to like them.  So why did I pick one, well they are cheap and I don't like Intel (personal thing nothing to do with their products).  The main reason was both AMD and Intel have new CPUs round the corner, Zen and Kaby Lake late 2016, so the 8350 is currently a stop gap measure.  Early Zen benchmarks look promising so I may pick up one of those, we will see.

 

I hope some people find this post useful and I'll see you in the skies, don't worry I'm useless been away from flight sims for too long but at least I can play the game without wanting to kill myself now.

Hi D4rkR3aper, From my experience with this processor AMD 8350 FX BEdition  and this simulator, you will never have good performance.

 

I do not understand why, but if you tell him that I have another PC using the processor and I never worked well

 

I can only give encouragement to hold on until you find a solution, or you buy an Intel processor

 

Salute and I'm sorry to say these words

Write a ticket to the support, i know another guy with 2600k with same problems. Some patch good performance some patch bad performance. Do you have change the gpu driver? You can also reinstall the game.

If its related to the change in patch is it really the processor
