Performance issues (stuttering - graph included)

I have a rather decent PC with a 5800X3D, 9700XT, 32GB DDR4 components. The moment I move out of the city the stuttering begins. Its basically unplayable as I am getting strange hick-ups / drops for some reason.
I have no issues whatsoever with other games (Cyberpunk, high frame Overwatch etc.). Tried to switch from WLAN to Ethernet - that did not solve the issue. Any settings I should look out for? Performance graph added

change global chat channel to something like 2963 and type /clear
Shader cache?
can try to cap fps lower, as in juiced content you aint getting 180fps anyway. helped a bit for me
Disable c-states in bios? If your global chat or trade chat active for few hours type /clear.
I'm on Linux and for me it helped changing to Vulkan, maybe it's worth a try for you, too.
I was getting crazy stutters every 4 seconds on my high end pc with 7900xtx and 13700kf and the fix was so random. If you have Lian li fans, make sure L-connect 3 is turned off and set to not turn on when pc boots. For some reason that software was causing microstutters in almost every game I played, but poe2 was the worst.
Glad to see it wasn't just me. I'm on PS5, and it's been horrible since the latest patch.
Since you have an X3D chip are you using Process Lasso to manage your cores ?
I personally do that but for some reason POE2 really didn't like that, once disabled it was fine since
Also, how is your ping and is the game on a SSD ?
I tried some settings and found out putting VSync "off" (from adaptive) improved the situation! No stuttering currently (i keep the PC connected to Ethernet just in case).
I would like to see some FSR improvements (have heard its only FSR2? GGG is providing ... FSR4 would be so great and would put less stress on the whole system). POE2 is really demanding
I also had this issue and it wasn't actually a hardware or software issue for me at all, it was actually the servers causing the issues, like my local server was just a complete mess or something, and since we only have "lockstep" for PoE 2 and not "predictive" the server latency was causing stuttering.
I use a VPN when this happens and it completely fixes all the stuttering for me, i'm assuming because it forces the game to connect to a different server.
