stuttering in games

The real question here is why are you reaching 100% with your CPU. It doesn't surprise me at all that things are falling apart when you do.

Just throwing this in the mix, is it simply that this is a natural bottleneck of your CPU and you are just trying to drive the frame rates too high? The GPU is fine but your CPU is not? The 4090 is known for the fact that it out performs even the best current CPU's.

It's not your cable, by the way, if you exceed the limits of that you just get black screens.

So we are saying my intel 13900kf Is bottlenecking my GPU at 4k. This is not reaching 100% anymore in any of the cores. the max is reaches is 85% usage in a couple of cores?
to be honest I thought bottlenecks were limited at 4k...
cheers

Oh as long as you have it back down to 85% then you should be fine.

Yes, they are limited, but if you are hitting 100% in your CPU (and you now say you are not) then it could be a possibility. I mean something has to cause it and would not be surprised at all if you get stuttering if you hit 100%. But anyway all academic since you seem to have resolved the 100% issue.

I don't know. Stuttering seems to be the modern scourge of gaming. I have seen this sort of post so many times on Steam. Games that are perfectly smooth for one player are crazy stuttery for another. I remember Kena. That was completely smooth for me but people with very similar PC's it was apparently stuttering like crazy.

It is really strange and I have done a full rebuild in the last week and still get it! Farcry I just lost hope for unless I cap at 60fps.

Spider man plays pretty well with the occasional fps drop which causes a stutter which I would say is normal.

Forza is fine
Dirt 5 that game crashes
GTA is fine
Call of duty is fine
Red dead is fine but does sometimes fps drop resulting in a stutter…
Horizon zero dawn same scenario as red dead

I am not sure if I am overthinking it and expecting to get 0 fps drops causing a stutter in every game. Possibly I am expecting to much from the hardware….

But yes correct there is no 100% cpu usage like I had on my 12700k

The 13900 is a beast only temp
I thermal throttle is running cinibench but for gaming it’s all good.

I feel like GSYNC only really helps with smaller fps drops. Anytime something is say more than 30-40 fps difference it causes stutter! I did tried the Alienware OLED and was much worse on that I think cause it’s 1440

see if you get the stuttering with the gsync pendulum demo - to rule out games being responsible, and to see if your gsync works properly at all, and your cpu shouldn't be at 100% in this demo either

Just given this a go! There is no stuttering at all and also in time spy using 3D mark there is no stuttering…

ok, let's double check the cpu temperatures (and gpu while we're at it)

run hwmonitor
https://www.cpuid.com/downloads/hwmonitor/hwmonitor_1.48.zip

reproduce the stuttering in game

report min/ave/max temps and load for cpu and gpu

and tell us what cpu cooler you have

I have the MSI CORELIQUID 240R not the best cooler but it’s fine for just gaming annd has not caused and bottlenecks or thermal throttling in games get and the max temps I get are around 76 degrees and average is 70.

Load the maximum reached is 85 percent on a couple of cores

Honestly everything looks
Normal to be honest! And that’s what’s making it so confusing!

Cheers

I'm starting to think it's either something to do with the games (maybe they aren't optimised for your setup) or something to do with your perception (maybe you're ultra-sensitive). Neither of which you can do anything about.

I am starting to think the same. I think I am seeing the fps dips every few minutes and becoming ultra sensitive to it.

Farcry is 100 percent not me that game is a mess.


I just don’t know what is a normal amount of stutter in a game to be honest. It’s not like it’s every 3 seconds. Maybe every few minutes or so and then sometimes every 5 minutes

Long thread, but no data? Where is the video, where are the screenshots of stats.

Sounds like you have now two PCs and experience an issue.

So either a: your ultra sensitive to FPS drop (doubtful) b: you install some software as part of your setup that is bad or c: some electrical interference in you home (also unlikely)

Hello, thanks for the reply. i actually changed gpu today to pny 4090 as exchanged and was still the same issue as i have now! i cannot get my head around it. this is a video where you can see the fps low go down to 30 fps or so with dlss. same without dlss.

what stats would you like me to provide and i can share them?
just 1 pc but basically rebuilt it with all new parts. not sure what i could have installed to cause it either on a fresh windows install. Driving me insane.
