AMD Ryzen 3600X - Parameters Help
Hi Everyone,

I'm a longtime ARMA 3 fan who recently upgraded my CPU from an i5-6600K to an AMD Ryzen 3600X. I also have a NVIDIA Geforce GTX 1070 GPU. I never bothered with parameters with my previous CPU and never really noticed any particularly bad performance - the game ran pretty smoothly for the most part.

Since upgrading, I've noticed that the game is defaulting to higher graphics settings and the FPS is immensely better, sitting at about 60-80FPS. I chalked this up as a win and proceeded to make an ALiVE mission and this ran smoothly. For a few minutes. It seems that as AI spawned my FPS wouldn't slightly decrease, it would drop DRASTICALLY.

I though that this may be a fault with the ALiVE modules and decided to hit up the single player campaigns instead - they all run well until I start to encounter a few enemies and then suddenly my FPS begins to drop.

I've now searched far and wide for answers and I've played around with parameters and memory allocators and I just can't seem to fix the FPS drops. Does anyone have any ideas on how I can fix this?

Odd, I'm playing the original campaign at the moment and I haven't had an issue at all with three missions so far.

Don't use launcher parameters 99% of most hardware it will gimp your performance as the game has been able to auto detect hardware properly(not graphic settings). Ai is something tests cpu's with Arma 3's dated game engine

Ps question if you're long time Arma 3 fan why did you change to a cpu with slower ipc?

Hi Sgt Smash, thanks for the reply - so all of those guides and instructions recommending a change to the parameters are incorrect?

To answer your question, I'm not a tech-head, I know very little about the fine details when it comes to specifications - I didn't even know what IPC was until you mentioned it.

for arma 3 thats a downgrade

And that's because Arma 3 is poorly optimised for multi-core processors, is that correct?

Basically for most users yes, they legacy tools that most people who make them guides are recommending the use of them when there are major problems. your problem is a Arma 3 Ai engine problem lol, there some scripts/tools out there to help but they can only do some much and also depend on the use case.

What view/object distance are you playing at?

Yes that and games tend to like fast single core speeds over actual core count, even the ones that can use many cores

View Distance - 1000
Object Distance - 850

So what would those scripts/tools be?

i still dont understand why people are choosing ryzen. most games will never run that many cores/threads

They have court up a lot and not bad for a price to performance value tbh

I went Ryzen on the suggestion of friends - in their words I am "future-proofing" my PC build.

@Sgt Smash - what do you mean by what am I playing?

Future proofing has been a term for about 15 years when it comes to high core counts in gaming, there is a reason that future never came. in the future (pardon the pun) take advice from some new friends lol
jokes aside
What you are doing in arma heavily affects the performance e.g gamemode and how is was made and so on, hence why i ask

Well as I stated, I was attempting to make an ALiVE mission, this mission was on Takistan and initially the mission runs at over 100FPS. Once about 20 AI spawn it'll drop significantly to about 60 which is fine. Add a few more and before you know it, the game is chugging along at 20.

I also tried the main SP campaign and experienced smooth 100FPS that dipped slightly depending on the amount of AI in the area. This changed as soon as I got to the point where you wash up on Altis - suddenly it dropped to 60 on the beach and then dropped to about 20-30 while in Kavala.
