Bottlenecks with i5 6600k.

[DaftClub]

I have owned an Nvidia Geforce Gtx 1080 Founders Edition for a good month and a half now and in AAA titles such as The Division, GTA V and Battlefield 1 and have been experiencing some bottlenecks due to my cpu (i5 6600k). I have done vigorous testing and have come to this conclusion due to my cpu usually maxing out constantly causing stuttering and fps drops. To try and combat this I have overclocked my cpu to 4.5Ghz but that appears to have improved hardly anything. I have turned vsync on most of my games to try and ease my cpu maxing out but it has appeared to be less effective at stopping fps drops and stuttering than it used to be. At this point it's getting rather irritating, and I'm just really unsure if there is something wrong with my hardware or the 6600k is simply not cut out for my 1080, but many other people appear to say that the 6600k is a perfect fit for a 1080, which worries me that I may have a faulty part.

I am currently running:

Gtx 1080 FE
i5 6600k @ 4.5Ghz
16GB DDR4 RAM
And my monitors refresh rate is running at 70hz at a resolution of 1920x1080.

Cheers.

I see the problem here.

At lower resolutions, the games generally becomes more CPU bound instead of GPU bound, that's why GPU companies boast their flagship cards (other than the RX 480 and 580 xd) that their cards are made for "4K gaming"

So, at 1080p, the resolution that you're playing at, the 1080 isn't really working as hard as the 6600k, but you'll see that the 1080 will work harder at higher resolutions such as 1440p. That'll probably remove the bottleneck.

That's why you notice (sometimes) that when techtubers benchmark high end Cards like the 1080ti, they do it with a rather fast 6 or 8 core. Maybe even a 10 core xd AND they do it at high resolutions (maybe some do it at lower resolutions for lols) to lower the chances of a bottleneck.

So there's your answer 😀



Edit: also the i5-6600k is a good match for the GTX 1080, but they mean it is a good combo for resolutions higher than full hd. So (no offenses here) people don't usually buy a GTX 1080 to game at 1080p. A 1060 or 1070 will max out the settings at 60 or 70 fps. The GTX 1080 really caters to 1440p at max settings 60-70 fps and maybe 4K 30-40fps.

The i5 6600k should be fine with a 1080 at any resolution. A 6600k will hold a 1080 back to some degree at 1080p but it should not be causing stuttering and large fps drops, what are cpu temps? What is gpu usage getting up to in game? I linked a bench below with the 6600k gtx 1080 running bf1 at 1080p, there testing shows rather good frame times with the 6600k, it should not be stuttering.

Cpu temps don't exceed over 60 Celsius and gpu usage doesn't usually land over 55% usage.

I'm thinking its some kind of display driver or other software issue.

I keep all my GPU drivers up to date. How do I figure out what software or driver is causing the issue, if it is the issue?
