Possible CPU bottleneck, looking for solution

[StonedMagician]

Yeah. So I was benchmarking earlier today, and used Digital Foundry's results as a baseline. And in 2 games (AC: Odyssey and Rise of the Tomb Raider) I was getting significantly lower framerates than DF was (they got 99FPS in AC, I was getting 66 at the same settings). Below are my specs. Any help would be greatly appreciated. I just want to get advice BEFORE I try anything, so I don't end up doing the wrong thing and making a major mistake.

 

CPU: Core i7 5820K OC'd (via raised maximum multicorecore ratio from 34 to 42) to 4.2GHz

Mobo: Asus X99-A

RAM: 4x4GB G.Skill DDR4 2133

GPU: GeForce RTX 2080 Ti FE

I mean I'm fairly sure most serious released benchmarks on reputable sources for the RTX 2080 Ti were using the i9 9900K or i7 8086K and similar which are considerable faster at gaming than the i7 5820K by nowadays... not that but also running 3200mhz+ memory while you only have DDR4's default 2133mhz.

 

Have you factored that in?

[mxk]

what resolution are you running? You CPU is pretty good but definitely can't keep up with a 2080 Ti all the time.

 

 

also you have slow ram

If the CPU is running at 90+% all the time and the gpu is below 80%, yeah that's a cpu bottleneck.

this

 

the higher the resolution, the more you will be GPU-bound

 

hence:

 

at 1080p 144Hz your CPU would possibly be a bottleneck

So, the RAM might be the issue. Alright, well, I'll see about getting faster models and/or upgrading my mobo/CPU to something more recent. Also, resolution is 1440p. The thing is, in the Shadow of the Tomb Raider benchmark I actually beat their result by a few FPS, so yeah.

 

If I were to get, say, DDR4 3400, how would I go about OCing it? Would I just use XMP? Sorry, I'm pretty knowledgable about most PC things, but in this area I really don't know much.

gpu % readings can sometimes be pretty un accurate.... but basically if their cpu says 100% thats all they need to see. 

I've seen gpu's hit 100% usage just watching 4k video even though the gpu doesn't get hot and clearly isn't struggling with 2d video.

So should I really just bite the bullet and upgrade my mobo and CPU?
