The NA client runs extremely poorly for me. The game runs at around 20-30fps in lobby and small fights, but drops significantly in urgent quests to around 10fps, basically slideshow levels.
I can also repeat this problem on command by just opening up the customise menu, this drops my frame rate to 10fps instantly. This is definitely a CPU issue vs a GPU issue as this problem still exists at 480p vs 1080p.
In comparison, I tried installing the JP client as there's a few differences, as the JP client is 32bit vs NA's 64bit client.
Performance on JP is as expected on my laptop, with 60fps all around and my GPU being the main limiter as opposed to my CPU.
Some comparisons between NA and JP below.
NA, shopping plaza in front of fountain. 9fps with customise menu open.
JP, shopping plaza in front of fountain, 60fps with customise menu open.
The game seems to be using similar amounts of CPU usage in both clients, nor is the game using 100% cpu usage in either client. There's something wrong with the NA client that makes it run so poorly.
Specs: CPU: i5-1035G1 RAM: 16GB 3200MHz GPU: NVIDIA MX350 Both clients running on an SSD.
