Question Low FPS with a brand new 4090 and 5950x

[Nuts_From_Berk]

Hello guys I’ve ran into an issue with my new pc. I have a Ryzen 9 5950x and an Asus rog strix 4090 oc and I’m seeing people get around 300fps at 1440p with maxed out settings in games like destiny 2/rainbow six/etc, however when I go to attempt the same thing in destiny for example I’m getting anywhere from 90-150fps and I just can’t figure out what’s going on.

I’ve tried updating all the drivers, I’ve tried DDUing, I’ve tried changing power settings, nvidia control panel settings, some minor overclocking, yet none of it actually gets me up to what I’ve seen many others in my shoes get or even close to it. I was wondering if anyone has any insight on what could be going on (specs below)

Motherboard- Asus X570-E
CPU- AMD ryzen 9 5950x
Gpu- Asus rog strix 4090 oc
RAM- Corsair dominator platinum DDR4 32GB (2x16) 3600mhz
PSU- asus rog strix 1000w gold aura edition
Cooler- NZXT Kraken elite 280

cpu/gpu temp and usage durin g the game?

The gpu rests at about 50c and anywhere from
40-70% usage
My cpu sits at 55-60c and can has a usage of ~40% usage varying from game to game obviously

Try limiting the games to the first 16 threads of the CPU. You can do this either with an app called Process Lasso, or by going into Task Manager -> Details page -> Right click on the game -> Select "Set Affinity" -> Untick CPU16-CPU31

There's a quirk with gaming and multi-chiplet Ryzen CPUs where data sharing across chiplets is just as bad as accessing RAM, so this can reduce performance since games prefer low latency rather than throughput.

Thanks for the suggestion, I tried to do as you suggested however I noticed no difference.
There is one thing that i did forget to mention and its that on occasion i will get frame drops and then stuttering while at 90fps. Prior to getting this gpu I had a 3070ti and no issues with that one and im wondering if it could be a bad gpu and I need to RMA it?

Always monitor CPU utilization PER CORE. The amalgamated number you quote is an average across all cores and despite its prominence in Nvidia Overlay it's a nearly useless metric. You may very well be CPU bound but you won't know until you look at how all the cores are utilized. As for limiting threads I believe you can disable one CCX either in software (Ryzen Master, probably) or in BIOS. Multi CCX AMD CPUs such as these are not always the best choices for gaming due to the cores being spread across two chiplets, and the latency that introduces if game threads are spread across both. IIRC Ryzen Master had/has a Game Mode which would disable one CCX to eliminate this internal bottleneck. Not sure if this is still a thing on Win11 with its new scheduler or not. Might be something worth looking into.

I appreciate the suggestion, I did try what you said and i did notice some more stability than what I was experiencing prior however this made me want to see if i could revert it and get a better overclock going which I was actually able to and now its stable with spikes on each core only getting to about 70% load.

However I did forget to mention one thing in my post and that is that while playing games i will be getting a more or less stable average fps but at random it will start dropping frames and stuttering heavily, I'm talking ill have about 200 fps on average and then it'll half it and start stuttering and skipping and it'll be like that for about 30s and go back to normal only for it to happen again later.
