Bottleneck?

[BlinkW]

I recently got a new pc and when I started playing games I noticed I was dropping frames often and just getting overall very low frame rates. At first i thought it was maybe just windows 11 or another issue but Im starting to think its my CPU bottlenecking. Would a I9-11900k fix this or would I need something even better?
3090 TI
I7-11700kf
32 Gb ram 3600 mhz

Shouldn't be a bottleneck that would cause frame chokes other than maybe at 1080p low/very low settings. 

What games, what resolution/settings, what are the "overall very low" frame rates, and that's it falling down to in the drops? CPU and GPU temps are fine?

So far played both Dead by Daylight and Fortnite. Dead by daylight I played at 1920x1080 at low settings and was seeing consistent drops from 120 to 100 which doesn't seem like much but can be annoying. Fortnite i played at 1720x1080 on all low settings and would drop randomly from 240 down to around 100 and sometimes even into double digits. With my old pc which was a 2070 super and i7-10700kf i got consistent 200-240 with no spikes or drops. My GPU temp stays around 50-60 while being at about 20% usage only. Ive done lots of optimizations and stuff like that and nothing has seemed to have fixed it. So I didn't know if i would need an even better CPU or if there's just something im missing here but any help will be appreciated.

Ah yeah that does sound like the CPU is choking compared to the GPU (As the CPU is what feeds both its own tasks and delegates the GPU's and what goes into RAM or not, when it chokes that's usually why you get stutter as essentially the whole system waits for the CPU). 

 

I... don't know that there is a CPU that can properly keep up with a 3090 Ti in 1080p low. A 12900K would have the most chance, but even then that workload is usually used for testing the limits of PCIe bandwidth not actual fps testing. You need to up graphics settings, resolution, or not use a 3090 Ti for 1080p low.

Something is definitely wrong, but more importantly, why do you have a 2000 dollar PC to play at ancient resolution and low settings..?

Did you build it yourself? BIOS updated? Temps all look ok? RAM working in dual channel?

Built myself, good temps, and everything's updated

While I fully agree, using that machine to play at 1080p low settings is a really poor choice of how to spend money… it wouldn’t cause things to run poorly. It would just very quickly run into a cpu bottleneck… but that would still produce hundreds of FPS. Something is wrong, just need to figure out what. 
 

But, I fully agree. OP needs to spend some money on a real monitor, and not play at low settings because for 1080p low gaming, a 2060 and a i5 8600 would be just about as worth it.

What are the temps of CPU and GPU in stress tests, and also what are they while in games? What speed is the CPU boosting to in game load, or really any load? Two sticks of RAM, correctly working in dual channel? Is anything overclocked?

I haven't actually tried running any stress tests to be honest, my gpu stays around 50-60 and my cpu sits around 50-65. My cpu boosts to around 4700-5000 mhz. Im using two sticks of ram both working correctly and nothing is overclocked.

Try to play the games in 1440p or 4k resolution by using Nvidia's DSR.

3080 is known to bottlenecked by 1080p, I'd imagine 3090 ti would be worse.

I'll be piling on the poor choice you made, 3090 ti on a 1080p monitor? You should do research before buying anything, if you did, you'd know this issue.

These are the sort of frame you should be expecting

Also,  What motherboard do you have?

I actually ended up putting my old 2070 super into my pc and noticed that I was still having the same problem, so maybe it does have something to do with windows 11 or maybe another part in my pc.
