So I finally found out what the issue was.
I enabled visualization of what was using my NVidia GPU and noticed a process called igfxupdate.exe using GPU but not show up on task manager. Strangely enough igfxupdate.exe is supposed to be the updater for my intel graphics card so it should not be using GPU at all.
I found this:

“Hi, after several hours of attemps I think I finally found the offender:
much probably a Trojan Generic KDV 792778, it pretends to be the windows service “Search Indexer” and it creates the fake executable: “igfxupdate.exe” which tries to connect in internet and rises the cpu load all the time till you open the task manager to hide itself..
So I solved the problem like this:
in the windows services management console I disabled the above fake windows service (it was in automatic start mode) and after I deleted the igfxupdate.exe file that was in the windows system32 folder..
I rebooted the pc and I deleted the same service with the command: “sc delete SearchIndexer”..
problem solved! cpu back to normal level, not more unwanted connections and not more igfxupdate files around.
anyway for more safety it’s better to do also a complete scan with a good antivirus/malware software"
Well for me it certainly solved my issue, now GW2 is running fluently again!
