Max was at 99%. How do i check the cpu ?

you say "max"... I need the average/typical usage. Was it typically almost entirely being used all the time? If the GPU is able to consistently work as hard as it can (A.K.A 100% Utilization) then that means that you are not bottlenecking it. No other component in your system is holding it back.

 

You can check CPU in any number of ways. The easiest being opening up windows task manager, going to the performance tab and monitoring CPU usage. there are 3rd party programs you can download such as HWmonitor or whatever you like in order to have a better view of things.

[Matthew52]

The AVG GPU load was 33%. The CPU was at 100%

[Matthew52]

Ill run the benchmark on Valley right quick

Hey guys, this is my first post here on LTT so I'll get right into my question! So I finally got my hands on a EVGA 1080 FTW edition and I am super excited about it but, there is one thing I may have over looked. I believe my cpu is creating a pretty substantial bottleneck. I have the i5 -4670k and with games like rise of the tomb raider with everything on max I am getting 40-50 fps opposed to the 144 fps everyone is benchmarking out. Could it be my cpu or could the be a different underlying cause to this substantial difference in fps? 

yes, your CPU is a bottleneck. In order to make it "less" of an issue, you can do one of two things.

 

ONE -> Get a 4790k

TWO -> Get 2400MHz RAM. Yes it may sound strange, but from my own testing, and other people too on these forums, when a CPU is bottlenecking, increasing RAM speed can have a notable impact. When combined with a mild OC, everything gets better still.

 

Also, to all you other idiots who are sure to come rushing to this thread and claim a i5 wont bottleneck a 1070 or 1080. You're wrong. An i5 will bottleneck the shit out of a 295x2 on a good day. On a bad day, you can get equal FPS with a fucking OCd FX 8320 (yay, moar cores, moar MHz -> same FPS. ), which is basically equivalent to a 1080..

 

A 980Ti will be mildy bottlenecked a Haswell i5.

A 1070 (980Ti + 5%) will be bottlenecked by a Haswell i5.

A 1080 (980Ti + 20%) will be clearly bottlenecking a Haswell i5.

 

Accept it. Move on and stop the i5 glorification.

i5s are overhyped. your is a major bottleneck. Get an i7 or deal with it.

At 1080p 144Hz your i5 is a major bottleneck. upgrade to a 4790K

144hz on your monitor does not at all influence your FPS in game. It only makes a difference in specific cases when your PC is pushing fps below 144 which is the refresh rate of the monitor, which means that instead of a conventional 60hz monitor, which draws the picture 60x every second, it draws it 144x, making the picture appear more fluid and smooth. Thus if your framerate dips below 144 you will feel lag and more jagged gameplay because when you are used to playing games at 144fps or above (such as Dota 2, CSGO, even minecraft etc, which are not hard to push 144fps+ in) and seeing the picture 144x a second, you will notice the dips, especially if at a high margin of 30 fps or so more.

The bottleneck they're describing has absolutely nothing to do with having an i5. Please don't advise people to throw money away on things that won't make the difference they're looking for.

[Delicieuxz]

Here's Rise of the Tomb Raider on the exact same CPU / GPU as the OP. This setup is getting the same FPS the OP describes, but... it's running Ultra settings at 4K resolution.

 

 

Tip: the CPU is nowhere near being bottlenecked, and is far less utilized than the CPU.

 

Conclusion: an i5 does nothing to bottleneck a GTX 1080 in Rise of the Tomb Raider

 

Also, bonus tip: Having an i5 does either literally nothing, or virtually nothing to bottleneck a GTX 1070 or 1080, except in rare cases. And even then the amount of bottleneck is not worth worrying over.

[Sintezza]

I dont think that rise of the tombraider is realy cpu demending.

Its also a DX12 title if im right.

i suppose you have a driver issue.

Because yeah the i5 will be a bottleneck at lower res like 1080p for example, but it wont be that bad.

Which resolution are you gaming at?

wanna hear a joke? A i5 does not bottleneck a 1080. Huehuehuehuehuehuehue

1. You have a flaw in your logic. A bottleneck is higher with lower res and becomes smaller with higher res. So in some games the i5 will bottleneck the GPU at 1080p, but not at 4k, because you put more load on the GPU.

2. YES A i5 bottlenecks a 1080 at 1080p, get over it.

 

Watch this, a 1070 is being bottlenecked, by a i5, now you ad those 20% performance ontop of the 1070 and the bottleneck becomes bigger.

Although the i5 does bottleneck the gtx 1080 he shouldn't be getting that little fps. 

with a gtx 970 this guy is actually getting better fps than op with everything maxed out at 1080p.
There is another issue which could actually be driver related since the new nvidia drivers ruined performance for some people. I would recommend op to revert back to some older drivers and see if his fps gets better.

Wow, aren't you desperate to give kudos to yourself (while completely being wrong and missing the thread subject, as well as completely butchering the context of the post you're responding to).

 

The reality is that an i5 will not bottleneck a 1070 or 1080 to anywhere near a level that brings performance of a game down to the levels the OP is describing. Also, any given i7 will bottleneck a gtx 1070  or 1080, because putting the next-higher tier i7 into the same machine with the same 1070 or 1080 will result in higher FPS. That doesn't mean the GPU was being bottlenecked. And if it did, then every system on the planet is being bottlenecked.

 

In all practicality, any bottleneck of a 1070 or 1080 from a decent i5 will be rare, and also not so much that it's a big deal. Sorry, but your tired "bottleneck" crusade is based on an overly simplistic perspective of things.

 

Like I said above, the bottleneck they're describing has absolutely nothing to do with having an i5. Please don't advise people to throw money away on things that won't make the difference they're looking for.

 

BTW, in regards to your youtube video comparing a 1070 and 970, I have a GTX 1070 in an i5 2500K system, and my FPS dominate GTX 970 FPS.

If your goal was to make yourself out to be a clown, then, yes, you've succeeded.

waow you did not see the video, a GTX 970 got the same FPS as a 1070 in crysis 3 at 1080p, if that is not a bottleneck you can call me Bill.

 

You have no idea of what you are talking about at all, you live in this dream world that a i5 is plenty fine for every single GPU on the marked, IT IS NOT!

 

Also OP runs at 1080p not 4k and if you knew anything about GPUs you would know that if you have a bottleneck of lets say 10fps at 1080p, it would be maybe 3-4 FPS at 1440p and be gone at 4k, because the GPU would be able to run at max speed without getting held back from the CPU. 

 

Oh yes every single system on the planet is being bottlenecked, most of the time people have a CPU that can handle more powerful GPUs and that is a GPU bottleneck then. The only way not to have a bottleneck anywhere in your system is if every single part is running at 100% and nothing is being held back by anything, but that is just insane and would never happen.

I run at 4770k and had a 780ti, I had a GPU bottleneck and I still do, because my CPU would be able to handle a better GPU, again only if every singel part of your system works at 100% and cannot performe any better at all no matter what, then you don't have a bottleneck anywhere in your system.

 

I am far from making a clown of myself, but you on the other hand you are, I have shown proof of a bottleneck at 1080p while you have just linked to a test with 4k, but what has 4k to do with 1080p here? Nothing

Op isn't talking about crysis 3 however he is talking about rise of the tomb raider which isn't as cpu demanding. Does an i5 bottleneck a gtx 1080 in crysis 3? yes. Should/does it bottleneck a gtx 1080 in rise of the tomb raider? No. Op most probably has a driver issue.

There allways will be a bottleneck at a certain point / scenario no matter which cpu.

How higher the resolution is you play on, how less cpu limmited you will be getting.

Since as going up in resolution, the load on the cpu doesnt change that much.

Thats why at 4K you are pretty much totaly gpu bound in most games with a single highend gpu setup nowdays.

 

If the OP games at 1080p with a GTX1080 then yes the i5 will limmit the cards max performance.

However the bottleneck even at that low res should not be that massive.

In this case there must be something else wrong, a driver issue or what not.

If think that the OP said something about only 33% load on gpu and 100% on cpu.

Which is realy low, there must be something going on.

Either a driver issue, card issue, software issue.

or maybe a virus or malware infection eating cpu resources.

This isn't an i5 vs i7 thread, and nobody but you and don are riled up and treating the subject like a team sport. The OP wants to know if their GPU is being bottlenecked, and looking at other benchmarks, it seems very clear that having an i5 is not bottlenecking their system in RotTR.

 

BTW, you sound like you think I'd care if i5s weren't competent, and that I'd want to resist that acknowledgment. But if you'd read other posts of mine on these forums, you'd know that I argue in favour of big and rapid performance progression for PC gaming. I wouldn't be saying an i5 is, other than in rare cases, fine for a 1070 or 1080, if it weren't the actual case. But it is, and while an i7, and a faster CPU is obviously better, talk of bottlenecking by some people is overblown to the extreme.

 

 

Btw, your video comparing a 1070 and 970 is rendered moot by other videos which show otherwise. In your video, the GPU utilization is around 50 - 80%. In this i5 GTX 1070 video, it's at a near-constant 99%.

 

Although your video took place in the hyper-threading intensive grass area, that doesn't make a case against general i5 pairing with a 1070 or 1080, because that is one of those rare exceptions in gaming, while 98+% of other gaming scenarios are fine. It isn't meaningful to tell people that an i5 will bottleneck their 1070 or 1080, when in 90+% of gaming situations, it won't.

[Matthew52]

Okay. Since some of you guys are looking at crysis 3 I booted it up and put everything on high. Im currently getting around 60-70 fps with dips into the 40s. with an average of 19% GPU Load is what the box is telling me.

[Delicieuxz]

Which areas in Crysis 3? Here are some Crysis 3 i5 GTX 1080 videos, and the GPU is almost always at 99%.

 

 

 

 

Have you tried uninstalling the display driver using Display Driver Uninstaller ( http://www.guru3d.com/files-details/display-driver-uninstaller-download.html ), and reinstalling the latest driver?

So i took my gpu over to my friends house that has an i7 6700k and I gained a substantial amount of fps in games and everything. In valley bench mark i had 120 fps at 1080 with ultra hd and then at near 4k i had an average of 60fps. Then with GTAs benchmark i hit a constant 100 fps at near 4k. I also removed the drivers from my computer like you guys said and it still didn't do anything. So it could defiantly be the cpu but if it isnt then i dont know whats up.

Which program are you using to gauge GPU utilization in Crysis 3 on your PC, and can you post a screenshot of the performance graph?

[Delicieuxz]

Well, here're two videos that can be used to compare the same areas in Crysis 3 on a i5 6600K with GTX 1080, to the same areas in Crysis 3 on a i7 6700K with GTX 1080, both running at 1080p.
 

The i5 6600K system reads 99.3 FPS at the same place where the i7 6700K system reads 154.2 FPS. You can go through the videos and pause them at different spots, to see if this accounts for the FPS difference that you're experiencing.

 

99.3 FPS at 0:38

 

 

154.2 FPS at 1:15

 

 

If those FPS differences are reliable across i5 / i7 systems in Crysis 3, then I guess C3 would be heavily bottlenecked by an i5 system. However, the GPU utilization is at 99% in both videos.

its not actually DX12. its DX11.3, same as they use in XBOX ONE.

 

The game only use the GPU features of DX12, not the CPU or lower API overhead. This is why there is little to no boost for AMD cards in "DX12" mode, because it is litterally just DX11 with a "Async compute" and "Async Shading" plugin attached to it.

 

Same applies to HITMAN.

 

Only Ashes of the Singularity and Total War: Warhammer is actual DX12 from what i can see.

 

Not sure about BF1, but i suspect that too will be based on DX11 and that the DX12 mode will in reality be DX11.3, which is basically lower level then DX11, but nowhere NEAR as low level as DX12.
