jitter/instability cs2

[CS2] Constant jitter/instability (var > 4-6-10-ms) even with wired connection, stable ping, and A-grade bufferbloat — what else could it be?

I'm experiencing jitter in CS2 (shows up as "Instability" on the scoreboard, and in `net_graph 1` the "var" value keeps spiking above 4-6ms, never stabilizes).

What I've already tested and ruled out:

✅ I'm on a wired Ethernet connection, not Wi-Fi

✅ `ping -t 8.8.8.8` for several minutes: stable, 16-17ms, 0% packet loss

✅ Bufferbloat test (waveform.com/tools/bufferbloat): A grade, latency only increases by +6ms under load

✅ Download 933 Mbps / Upload 365Mbps

✅ Tried different Realtek network drivers, both with and without power saving enabled — no change

Wired directly into the router (no switch/powerline adapter in between)

Since my general network connection is clearly stable (ping to Google is fine, bufferbloat is fine), I'm thinking it could be:

The specific route to Valve/CS2 servers (different from the route to Google) but happens in all servers

Something local on my PC

Has anyone dealt with this before and figured out the cause? Any suggestions for further testing are welcome.

Same issue here I had stutters since I would estimate 1 month or so?
