Ok so i am confused below are my computer specs
PSU: Super Flower AMP-1000r14HE
CPU : i7 6850 @3.6ghz
Main Board : MSI X99 Godlike Gaming
Ram :Corsair Vengeance 2x 8 gb @2666mhz
GPU : EVGA classified 580 gtx
and was running arma 3 at 60 fps last night on almost everything on ultra and today have changed my GPU to a gtx 1080 and my fps wont go above 14.

It doesnt matter if my settings are on low or on ultra. There is no change in the fps at all.
How is there a bottleneck ? If there was any it would of been the GPU and not anything else.

I find it strange that there is no difference in the FPS between low and ultra. That would suggest that there is something going on with your PC in general. Have you check to see if it is running at full speed when in game? i.e. The processor running normally, and not throttled down below its normal core speed? You can monitor this, along with your GPU speed, temps etc. by using MSI Afterburner and switching on the on-screen display. Here's a guide for setting it up.

This might give you some idea as to what is going on.

It doesnt have a video port , I mean the motherboard.


Yes , even double checked.

ARMA3 is quite CPU intensive, so maybe when you were using the older card, the CPU was doing that hard work, and now that you have a beefier GPU, it has transferred the workload more to the GPU and there is a bottleneck.

Did you ramp up the graphics settings a lot when you installed the new card? i.e. Switch on AA and higher draw distance etc? If so... lower them down and work up to a reasonable FPS. Bare in mind also that some ARMA3 servers are optimised better than others for low detail settings lower draw distance etc.

That's not how it works.

OP, check your CPU clockspeed and make sure it's ramping up to full when you're running your game.

If the CPU can deliver 60fps, it's capable of doing so regardless of what GPU OP uses. OP replaced their GPU with one several times more powerful, so at the same graphical settings it should not be any slower.

Since changing graphical settings doesn't affect framerate, that suggests to me the video card is not at fault. What seems more likely is that the CPU is stuck in a lower P-state, probably running at 800mhz. 14/60 = 0.23%, 3.6ghz * 0.23 = ~800, suspiciously close.

I did suggest that he check this factor in previous reply. I agree that it sounds like processor core speed issue. Although I recall increasing ARMA3's graphics settings after I upgraded my GPU before, and in that case... both the CPU and GPU got maxed out completely 100%....hence a bottleneck. When I decreased the GPU intensive aspects such as PP & AA, shadows & textures, the performance improved, but the CPU usage lowered to around 80-100% and even further when you decrease things like view distance and particle effects. Which tells me that both play a large factor with Bohemia's engine.

It is well known as an unoptimised engine when it comes to balancing between CPU/GPU and does take a little bit of tweaking and playing around to run optimally.

However i digress........check the CPU core speed in game as suggested.

This seemed to work thank you, However I have run into a new issue. I am running arma 3 @50 to 60 fps in ultra but after playing a while i get random spike lags that freeze my game at 4 fps and it wont work. after checking task manager it shows my memory working in a redish color (as if its all being used) when i clicked it to display the actual ammount of ram used rather than the % it was at 400 mb ?( I have 16 gb ddr 4 @2666mhz) is there a way to resolve this issue?
