Bottlenecking?

[ArchV]

Hey all,

 

I was inspired by the bottlenecking video ... I have a system that I "feel" might have a bottleneck but I'm not quite sure.  The main system itself was built in 2012, with pretty high end stuff.  Naturally the graphics card has been replaced since then, and therein lies my worry about bottle necks...

 

Here goes the specs:

 

Asus P9X79 Pro motherboard

32 Gig of DDR3 not sure what speed....

Core i7 3820, OC'ed stable @ 4.6Ghz.

Geforce 1080 Founders Edition

Dual Samsung 750 Evos in Raid 0

Some other big mechanical drives for storage...

Primary monitor, 34" ultrawide 3440x1440 @ 100 Hz

 

I do gaming... Things run pretty good, but I can't help but wonder if I'm missing out on more frames due to the CPU.  It's a decent CPU, but it IS 6 yrs old at this point.

 

Someone else told me on a different forum that "As long as its feels fast enough, its fine".  I can live with that answer honestly... but a good chunk of the games I play at 3440x1440 at max settings are still hovering BELOW 60 fps, usually in the mid-40s to 60 (sure, I could dumb down the quality settings, but wheres the fun in that?).   If the 1080 could run those games at a solid 60 or more by changing out the CPU, then that's pretty important information.  I'm playing No Man's Sky lately if you must know

 

Is there anyway I could CHECK to see if the CPU is bottleneck?

 

I can also post more detailed specs if needed, CPU-Z screenshots and such.

 

Thanks!!

should be fine

No Man's Sky's recent update seems to be running fairly mediocre even on high-end setups, so I don't think in particular that it's just the CPU holding your GPU back.

no, this is simply very taxing, talking about an extreme resolution and very high detail settings, your GPU would be the limiting factor in such instances, no doubt about it.

I don't see any reason for a bottleneck in your system.

Ok yeah in No Man's Sky, I monitored the CPU usage while playing and it never ever gets above 30%.  GPU of course always runs 90%+  So I guess at least in that game, CPU isn't an issue. I'm assuming low CPU usage is a sign that it is not a bottleneck.  That could be wrong though... maybe the 30% that IS used is doing it slowly

 

And thanks for all the feed back... and really that's the answer I was hoping for... because its the one that doesn't cost money

You can stress test and see if CPU/GPU usage goes 100%, if nothing prevents it from maxing out it's GG no limits.

No, games are just programmed poorly.

 

I'm sure Doom runs at a zillion fps and looks amazing

The CPU is old, but it's still adequate.

Depending on how the CPU is being used, you could still have an issue. Like for instance if the application is tuned for single core performance, then multicore processors won't help with it. But I'm going to assume No Man's Sky is at least designed with some multicore support in mind and that does looks like a low number for your processor

 

If there's a bottleneck that's "desired," it's the GPU most of the time.

I think you are simply overestimating the GTX 1080's ability to push 3440x1440 on ultra. While it's not 4k it's not exactly easy either and seeing 50-60fps is perfectly normal here.

 

Here you go:

 

Best way to see whether or not you are getting what you are supposed to is by looking at videos other people post ;-)
