Question why my fps is so low with gtx 1080 and i7-6700k

[Mörtti]

I play fortnite with 1080p monitor of 144hz. My pc specs are gtx 1080 i7-6700k 16gb ram 256gb SSD 1TB HDD and i cant even reach 240+ fps in fortnite. Sometimes my fps drops to under 144. Why it does that when im having good pc?

That's about right. Gtx 1080 isn't strong enough to keep fps consistent especially @ 240+ nor is your cpu capable of consistently preparing that many frames to keep up with other things going on in-game.

Your performance is fine for what it is.

And what settings are you using exactly in Fortnite?

 

[Mörtti]

So even others get 300+ with gtx 1070?
My average is 175

And what settings are you using exactly in Fortnite?

All low and still under 200 fps

 

[DSzymborski]

All low and still under 200 fps

Do you have a problem in any other games?

Do you have a problem in any other games?

Not really maby dota 2 is kind of low but not much big drops nd csgo is 300+ easy

All low settings and not other games dota 2 is kind of low but csgo easy 300+

If comparing videos, it's difficult to know how they've optimised the os in a way of gaining system resources toward a game. Typical windows configuration does have quite a few processes happening in the background and that takes away cpu focus on games. To improve in this regard, eliminating unnecessary processes can help, Winaero can do that for you.

They may have a stronger cpu than you, or may have cut down on all the background processes thus leaving more breathing room for the cpu. Small differences in PC setups can sometimes lead to huge performance differences.
Also, while they may be using a weaker card than you, you aren't helping your situation by running at the lowest graphics settings. With higher graphics settings, the gpu works harder and the cpu works less - vice versa with lower settings.
There's a balance that must be met with these things. Perhaps things would level out for you on med or high settings? I mean, a 1080 is stronger than a 1070, so why not actually use that extra graphics horsepower?
Doesn't make much sense to be running at the lowest settings with it.

Why does 200+fps matter, when your true fps is only as high as your monitor's max refresh rate, 144hz?

 

[Mörtti]

Well many have same cpu what i do and my fps is dropping under 144 and thats weird.

 

[Phaaze88]

Just having the same cpu doesn't tell the whole story.
You literally have to have the exact same specs as each other. A single discrepancy can make a small or large difference between similar builds.

As people suggested try to kill unecessary background processes. Other than that people you compare to could be OCd, got better luck with silicon lottery.

I see.
Although you have 16GBs of ram, you're only running in single channel.
Buy a new 2x 8GB kit, or get the exact same stick as the only you already have.
It's safer to go with the new kit though, because adding sticks that weren't packaged together are not guaranteed to work.

 

[Mörtti]

How much fps does that give and how fast should it be? 3000mhz 3200mhz or under 3000?

 

[Phaaze88]

It depends on the game.
Take these only as a REFERENCE, as differences between builds will skew results.
Single vs Dual Channel Memory

3200mhz is the current sweet spot in price/performance, so aim for that.

 

[Mörtti]

So in those videos differences are huge. Wow im gonna think about buy 2x8gb

 

[boju]

Yeah dual channel along with higher speed ram can improve a cpu's efficiency in heavy cpu games and allow for better fps minimums / less stutters.

Around 3000MHz - CL 14/15 or 16 is good.
