Hi,

I have this issue where the longer I spend on one map the worse my fps becomes. Going down from 60 (with vsync on, from 100 with vsync off) to basically 10-20 given enough time. Participating in group content with others hastens the issue a lot. Teleport to another map or relog resets the fps to normal.

I had this issue for years, assumed it was my old pc's problem, I recently got a new PC, but the issue is still here.

New PC:
Ryzen 7 5800x
Nvidia 3070ti
32gb DDR4 ram 3600/CL18
Samsung 1tb M.2 drive
1080p monitor
New OS - Windows 10
All drivers freshly downloaded and up to date

Further details:
Newly downloaded game client
No addons
Game settings maxed out
Microsoft antivirus
Temperatures don't go past 60°C (140°F)
The load on the CPU is minimal, around 16%, doesn't change over time
The load on the GPU is around 35-45%, doesn't change over time
Ram usage around 3gb, +/- 300mb, doesn't fluctuate further over time.
Doesn't happen in any other game.
I see no issues with firewall.

Any tips appreciated, I have however already tried everything I could think of.

Thank you.
