CS2 problems/stutters - need help finding the issue

[flow]

So my CS2 has a lot of stutters and I have no clue why

Motherboard: MSI MAG B650 TOMAHAWK WIFI
CPU: AMD Ryzen 7 7800X3D 8Cores @ 4201 Mhz
GPU: RTX 4070 Ti Super
RAM: G.Skill RAM Flare X5 - Low Profile - 32 GB
PSU: Corsair RM850e

As far as I remembered I should have all the power saving functions disabled in BIOS but tbh I am a noob in bios (I can check if someone can guide me on the names I should be looking for)
I have EXPO enabled
Internet is via TV-cable (DOCSIS) to Fritzbox 6660 and via cable to PC
WIN is debloated as much as I could
power plan is max performance


I do get some upload jitter in the ingame graph but I also think my 1%lows and 0.1%lows are very bad
I acually disabled the ingame graph to not get insane and do too much shizo tweaks
But disabling the graph doesn't help when I move around even tho my input stopped
Or jump and go under map for few ms
It's kinda funny - sometimes I lag around a corner and see if there is someone xD but I can't shoot with lags too so useless

My next thing I can try - buy 5G router (I only have cable internet of one ISP) but there would be 24 months I have to pay

If someone can help me I would much apreciate it, if more information is required I will do my best to give it

I would like to help if I could but lately a lot of people present issues that are hard to categorize. Lately I've had a lot of success with disabling Core 0 for games if you haven't tried that. Also try disabling HAGS and Game Mode.
I run this game on 5 year old hardware and AMD drivers from 2023 and get a low memory and low storage message on every startup but I never get a single microstutter or dip in fps.

I've highlighted a few things which I find potentially problematic:

1.) EXPO can be unstable out of the box and cause jitter/stuttering, especially on some X3D CPU's.
Could you take a ZenTimings screenshot of your current RAM timing profile?
For the least obnoxious / time-consuming way to deal with potential RAM instabilities—disable EXPO and reinstall Windows to W11 23H2 or 22H2
What other BIOS settings have you changed? A comprehensive & detailed list of things you've changed would be useful in aiding the troubleshooting process.

2.) You haven't mentioned which exact settings you've changed in Windows, what Windows version you've chosen (winver run command will tell you) and what Nvidia driver you've chosen.
Your options on the 4070 Ti Super are between 551.23 till latest (which I would avoid at all cost)
The drivers which you could test out are: 551.86, 552.22, 555.85, 560.70, 561.09, 566.14, 566.36 (there are a handful left which I haven't mentioned)
I would not go past R565 (last being 566.36), such as R570 & R575. They are severely buggy & lead to performance degradation.

3.) You haven't mentioned your peripherals (mouse, kb, monitor, headset, any other USB devices which you may have connected) and in which ports you've plugged them in. Could you mention them + show a image w/ your mobo's back where you've inserted them? A HWInfo screenshot of each connected device would also be of use.

guess u already saw my thread adressing this issue a few days ago. u can look through it and apply some of those fixes.
assuming ur pc is running fine. no throttle no software or hardware issues.

what helped me narrow down the framtimings by a bit:
fresh install 23h2.3 (local acc. no network - if ms acc. is used connect later)
only necessacry drivers (chipset, gpu, onboard devices) no logitech g hub
set max performance for ur gpu (also set high performance plan in windows)
u can try different nvd drivers. theres also a thread on this sub forum. im currently using 566.38 (always clean install with DUU - disconnect ur network while in this process so ms wont interfere u)
dont use game mode but disable smt in bios (cs2 ll run better without multithreading)
run ur ram in default (no EXPO/XMP) if this helped then potential ram instability
best results if had with 6000mt/s 30-38 1:1 FCLK fixed 1733 (kit depends on ur board ofc)
try disabling global c-states in bios (keep in mind ur cpu ll use higher voltages even in idle)
if not used: disable wfif, iGPU and bluetooth in bios)
experiment with rebar on / off
try different res and lower settings if possible
test different frame limiters (RTSS, ingame or driver level)
->frame pacing and overall optimsations of cs2 in its current state is nor really good so ive stuck to the ingame frame limiter (fps_max), this dont work properly either but dont adds extra delay
experiment with Process Lasso: either disable CCD0 for cs2 or set all threads to cs2. also higher the cpu priority

hope this helps

6000MHz EXPO kits can be unstable on some IMC + mobo combinations, hence why EXPO disabled is a good way to start the troubleshooting process. It gives the user a performance baseline to further evaluate any lingering jitter by using the process of elimination.
Disabling Global C-State Control is not advised by AMD according to their server tuning guides, even for latency-sensitive workloads.
They recommend disabling DF C-State instead for latency-sensitive workloads.
There's more nuance to this topic however, I assume every mobo is different in this regard.
I would personally avoid using ProcessLasso for any kind of affinity work, as it uses up CPU cycles & causes context switching, meaning it takes up CPU resources.

me too i will do benchmarks with it enabled,i have it disabled for now.

I have WIN 23H2 so all good there ig
I am motherboard noob, but I got some infos that may be usefull:
- ErP Ready 0
- DDR5 Nitro Mode 0
- Infinity Fabric AUTO
- UCKL DIV1 Mode AUTO
- Fclk VDCI Mode Pref AUTO
- Precision Boost Overdrive AUTO
- SoC/Uncore OC Mode 1
- X3D Gaming Mode 0
- EXPO 0 (did that after your commend)
- High-Efficienty Mode AUTO
- DRAM High Voltage Mode 0

As for Hardware I have Wooting 60HE, Finalmouse ULX, Zowie XL2566K@360Hz and for sound Komplete Audio 1 Interface
I did now with help of HWINFO seperate the USB-Controller on all three devices

As for GPU-Driver I have 31.0.15.5123 (device manager)

FYI: I disabled EXPO today before playing and I had some improvements, I sometimes still have major stutters but I think this could be my internet(?) I need to benchmark again tomorrow and will update u guys

HWINFO:

HWInfo CPU, GPU, MOBO

Thank you for mentioning some variables which help the troubleshooting process.
ZenTimings can be downloaded from here, if you'd still like to post a screenshot of your RAM profile
The exact model number still isn't clear, since there are a multitude of variations which are labeled as F5 6000J3038F16GX2, such as -TZ5NR, -FX5, -TZN5, -RM5NRW...
But since you are running EXPO disabled, it's redundant.
Here are a few BIOS settings which I can recommend you to change:

1.) Overclocking\Advanced CPU Configuration\
SVM Mode = Disabled
FCH Spread Spectrum = Disabled

2.) Overclocking\Advanced CPU Configuration\AMD Overclocking
SMT Control = Disabled

3.) Overclocking\Advanced CPU Configuration\AMD CBS
IOMMU = Disabled

4.) Overclocking\Advanced CPU Configuration\AMD Overclocking\Precision Boost Overdrive
Precision Boost Overdrive = Disabled

5.) FCLK Frequency = Auto

I would also set SOC/Uncore OC Mode = Enabled and set DF C-state = Disabled

UCLK DIV1 Mode should also be changed to 1:1 (to match UCLK & MCLK, which would be 4800 for your RAM kit with EXPO disabled)


I would strongly advise to reinstall Windows after finishing with finding BIOS settings, since your previous settings could've corrupted your installation & thus alter your perception.

After finding your finalized BIOS settings & setting up Windows (with disabled Windows Defender & Windows Updates with registry edit), try playing on those settings for a week and see if you prefer it.

Guys I found a reddit post (I can't link it) it is called "Stabilizing Packet Loss & Latency on Starlink for (semi) Competitive FPS Play (Gaming)" by u/CompleteTowel

I tried out the method he used and improved my main problem - that is upload jitter and network instabilities

Now I still want to increase PC-performance to get rid of those nasty 1%lows, just not now as I need to look if I have any important data before getting new windows install (I just set my monitor to 240Hz in the meantime)

I basically don't have the time rn to do so in a proper way

Anyway, using speedify stabilized my internet a lot - I cannot explain why as both connections still go through my router and ISP - and I have to test more in the folloing days, as we all know internet can be good one day and bad on the other

Please read the reddit post I mentioned and give me your opinions on what you think about it
