Micro stuttering

Hi all looking for a little help. I'm getting quite bad micro stuttering in high end games, bf2042, hitman 3, rdr2, dying light 2 etc.

Running i9 9900k @5ghz 32gb ram @3200 zotac 3090 Samsung 970 m.2 z390 aorus master

All temps are fine I'm not seeing any thermal throttling through hardware monitoring I even did a fresh install of Windows and drivers but issue persists. Frame rates look decent usually between 60 to 120 in these titles at 3840x1600p. But I 99 percentile drops as low as 27.

I have seen other 3090 and 3080/ti owners complaining of same issues on other manufacturers cards wondering if anyone had any idea?

I was considering a 12000k but was going to hold off for the AMD next Gen

I would grab intel if you need the performance now, it's a very sizable jump in performance that you would benefit from with such a GPU.

The 12600K is more than enough CPU.
 
Do your benchmark scores for CPU/GPU/SSD show no problems?

Have you tried latency monitoring?

Have you tried playing with only hardwired equipment?

What is the monitor?

9900k is not that great anymore and certainly bottlenecking that 3090.

On what planet? Because it sure ain't this one. An overclocked 9900K is still an amazing gaming CPU. There is zero chance that there's any serious bottlenecking going on using one at 1440p ultrawide. The single and only upgrade path from one is Alder Lake, which is in no way going to be worth it just for gaming at that resolution. Anything else on the market is a sidegrade at best.

Lol fkn no.

I am at work or I would destroy your bs.

Ask those guys with 8700k on toms hardware lmfao.

That 9900k is really delivering with its extra 3%

I don't need to ask anybody. You need to get a clue.


The 12600K you recommended is usually less than 10% faster than a stock 9900K even at 1080p with a 3080. Lows are comparable. At 1440p ultrawide you're going to be GPU bottlenecked 99% of the time even with a 3090. If the 9900K is in need of replacement, so is literally every non-Alder Lake CPU on the market, including your 5800X.

Are you running afterburner and rivatuner?

If so could you put up a frametime graph?

Are the stutters rhythmic? ANdd happening in the same way across different games? If so it could be a background application.

If it's random frame time spikes it could be down to the game engine.
 
8700k here and still going strong, I highly doubt that a 9900k is bottlenecking a 3090. That's 8 cores and 16 working threads

The only thing wrong with the 9900k is temperature it's a hot chip.

10 FPS difference in the only CPU demanding game in the video - Cyberpunk. Not a reason to upgrade and I agree.

Lets dive into why I said this is a bottleneck.

This thread from Tom's hardware has a guy that plays a game that focuses on the weakness of said CPU, IPC. It is comparable to Zen 2.

Read through and understand the conclusions met.

Now this is the 8700 vs the 9900. Little to no difference right?


So tell us all here how the OP is not bottlenecked with his RTX 3090 ??!?

Only one of the games the OP plays was in your video.
 
I believe I've found the issue. Turns out my PCIe 3.0 slot is running at PCIe 2 speeds. I'm going to remove one of my m.2 drives today to test.
 
Hopefully it is that simple but if not use something like Process Explorer to see what is running in the background - could be a maintenance task or similar taking up CPU time. Monitor DPC latency to see if there is a driver flaking out, etc. if you are overclocking RAM try removing the overclock as sometimes RAM can appear to be stable but still cause stutter and/or try other timings/frequency as sometimes a specific combination of hardware/software with certain RAM settings just doesn't seem to be smooth for whatever reason.

Thank you and all of you that replied
 
Problem with stutter in games either major or various forms of micro the causes can be so diverse - even including disparity between CPU and GPU - but I'm running a 2013 era CPU with a 2020 era GPU and that isn't causing micro stutter heh and certainly a 9900K is still capable with more modern GPUs.

I've had it before with things as simple and difficult to diagnose as an overheating motherboard chipset because the fan was no longer spinning as fast as it used to for some random reason :s
