GTX 1080 bottleneck?

[setligth]

hello, im quite new to this forum and stuff.

so here it goes, i dont know why but i playes bf4 a couple of days ago and then i noticed that i was only getting about 50% GPU usage and 80% CPU usage.

heres a picture taken with my phone: http://imgur.com/a/So8ky

 

i have a GeForce GTX 1080 MSI gaming X OC mode on + OC @ 100 MHz, 16GB GSkill @ 1333MHz, Intel Core i7-4790, Gigabyte GA-B85M-HD3 R4

i dont think the rest matters

 

idk if this is normal with bf4 but i dont think it is supposed to be like this.

Something is wrong. RAM used 2GB? With BF4 on? No way, you exceed 2GB with an internet browser on.

 

Also, i7-4790 doesn't bottleneck a 1080.

okay, i thought it was just weird how it was only using 50% of the GPU and 80% of the CPU so it thought the CPU wasnt fast enough.

are you playing at 1080p ?

also, with 60hz, why do you care ? 60 fps max

[setligth]

im playing at 1440p 144hz with GSync, so yeah i care ;_;

[Flesky015]

Almost no difference between 100fps and 144, just let it be unless it's a problem in more games

[setligth]

okay

[S1-]

do you know the cpu usage while playing the game??

because if the cpu usage is near max example around the 90%

and your gpu is running around 50 or 60% than thats a bottle neck

[setligth]

it says it right in the picture http://imgur.com/a/So8ky

yeah that bottle neck but it not bad or good you will be fine

a severe bottle neck is a cpu running at 90% percent

and gpu running low at lest it not bad though

[setligth]

sure

You'r CPU is not exactly a bottleneck per say but it is holding your GPU back to draw additional frames in this case. You probably would see a few more frames with higher bandwith memory, like 1866mhz aswell as with a higher OC on the CPU, but personaly I would not bother with that, as the results will really be deminishable... well maybe try the CPU OC cus its free and I dont think 3.8GHZ is the max for the 4790 non K that you can go with multiplicators, should go up to x40/41 aka 4.1 or 4ghz if im not mistaken.

 

However none of that I would say is an actual "bottleneck" that should concern you.

 

Eurogamer / Digital foundry did a good test between CPU's a year back, with an OC'd Titan X, which should about the be same power as your, lets just say "mildly" OC'd 1080.

 

stock CPU:

 

OC to 4.4 GHZ:

 

Even a 6700k at 4.4 GHZ sits between 105~ to 135~ FPS in the campaign level they benchmarked on BF4, so if you reach 105FPS~ on multiplayer with 1333mhz RAM and a 3.8ghz 4xxx series CPU, thats a very solid outcome I'd say.

 

 

Edit: and as pointed out by others allready, something is off with your RAM usage, firstly windows + bf4 will need way more than just 2GB RAM.

Secondly if you have 16GB installed, and the overlay shows 2GB used to 8GB available, thats 10GB - where are the remaining 6GB RAM?

Could be the overlay you are using is false or that you actually are having RAM issues, I'd look into that.

well, thank you very much for the long repost :), but i dont really know how to change the clock speed of the CPU, ive tried it in BIOS but it wont change cuz its a non-K CPU. im a noob when it comes to this........

You allready did overclock your CPU, the stock speed would be 3.6 GHZ, you are at 3.8.

Either that or you did enable turbo mode - which basically is an overclock aswell.. just one that you could see more like a boost clock on any modern GPU.

 

Anyhow its rather simple really, even non K CPU's can be overclocked with the multiplier to a degree as they have a maximum multiplier set in place, which as I allready posted is usualy at least x40, while K CPU's dont have that - you could make a K CPU go up to x60, not that it would work but the "option" is there.

For example I can get my non K 3770 up to 4.1 GHZ with the multipliers alone and not even touching the baseclock, if I want to go higher than the 4.1 GHZ I need to fiddle with the baseclock and thats where overclocking gets really complicated - but in your case the baseclock is not relevant.

 

If you tell me what motherboard you have I can probably guide you throu the OC process, seeing from the pic you posted 50°C on 80% CPU usage = watercooled so temps wont be an issue and stability is almost always no issue either with non K CPU's.

my mobo is the b85m-dh3-r4 from gigabyte, a cheap one. my cpu is being cooled by a cooler master hyper 212 evo. im not gonna watercool, i dont want my 800 euro gpu to be destroyed by leakage, thanks for the help so far.

sorry for my "bad english" if there was any.

well on your phone we see that in the menu you put 60hz refresh rate

[setligth]

thats the tock rate of the server not my refresh rate, the tick rate says how many times the server updates per second

[setligth]

thats the tick rate*
