Hi everyone
I have had really bad jitter in CS2 for about 3 months now. Last year the game worked flawlessly, but now it is slowly becomming unplayable. I don’t know when the issues started as I had a longer hiatus with the game. The frame rate is stable, only packet problems. I don’t have any other FPS games to compare it to. Loading and using regular web pages works just fine.
It seems that there might be compounding issues. Things I noticed contribute to more jitter:
Pihole (default setup CouldFlare DNS, both IPv4 and v6)
Fedora kernel
x11 session
What I tried:
switching to an older kernel 6.15.9 -> 6.14.9
using CachyOS kernel (reduces jitter, but causes serious issues with Electron apps)
switching from Wayland (the default) to x11
using Gamescope
verifying game files
disabling Pihole and unpluggin it from the network altogether
My setup:
Fedora 42 with latest updates and kernel 6.15.9, CachyOS kernel 6.16.1
Ryzen 2700 and RX6600, 32GB RAM
I have no idea what to do next. The internet doesn’t offer any solutions and everything I have tried so far does absolutely nothing. It could just be a bug in CS2 itself, but it’s strange that almost noone is reporting it. Any suggestions?
Thanks!
I don’t use any wireless connecticity for my PC, just a plain old ethernet cable.
The ping test was fine. 176 packets received, 0% lost, only 3-4 outliers with 150ms, average 15ms.
ethtool was fine 1000mbps and full. Bufferbloat was fine too, 20ms.
I’ll try cl_interp_ratio tomorrow and report back.
Noone is wwtching anything in 4k, maybe some YT on phone (I have cable).
One site that gave me some bad results was packetlosstest. Someone on reddit suggested using it to test some CS preset. No lost packets, but about 8-10% are late (more than 40ms).
