Good luck.
In a lot of cases like that (very low FPS when expecting much higher), it’s been because of the GPU being in the wrong slot. Use tools such as GPU-Z to confirm it’s running at the correct speed. It doesn’t affect other games much, but GW2 is really good at catching system problems.
If you have both an integrated and dedicated GPU, GW2 may be using the wrong one. It became more of a problem when they forced the 64-bit client, since it’s based on the filename.
If this is not a new installation, delete the %appdata%/Guild Wars 2/ folder, and if it exists, Documents/Guild Wars 2/Local.dat. That’s where your local system settings are stored, where changes in the hardware/system can cause problems.
yep checking if you have more then one gpu in the system and what one the system is using can be good. other thing that affect fps in gw2 is the cpu bound issue; this happens when there is to much graphic at same time and the direct x high level driver need to solve programmation error for memory allocation and send the graphic job at the right place. when that happens. the graphic job is stopping on the cpu and not reaching the gpu to be render at same time the dirext x driver is also using the cpu to solve those issue to send the job to the gpu. you can also look if you are running any other heavy program on the cpu in the back ground when the fps drop example: system performance check that use your system at peek performance to see if everything is working, also security scan, video app or picture or graphical app. anything that use a lot of cpu power on your system can cause gw2 to run slow. since gw2 use direct x 9 a high level api, the only way for gw 2 to fix this would be to upgrade to direct x 12 low level api. since in that case the driver to fix issue is very small but the game devs need to make sure there is no error before it is release. no safety net for the dev in that case and more work for them,more testing and bug correction. maybe in a couple years.
only have one gpu and it hasnt been moved so if it was in a wrong slot it would ve broken down since the first time i tried playing the game i’d think and not after years of playing it , as well as other games would probably get similar problems but they all run just fine some even run at 150-200 FPS its only gw2
