I'm not very good with computers, but at least 1 of my friends has reported having the same issue as me.
I run 2 monitors, and when i am on the character selection screen my PC starts going super slowly, and my GPU usage shoots up to 100%. When i am logged in to the game it goes back down to 71%. I play the game in windowed fullscreen. I tried playing in windowed & fullscreen, but it had no impact on fixing my issue.
Eso is the only application i have this issue on (and it only happens in 1 specific instance, when on char select screen) and this never happened before the patch. I already experienced this issue while on the FOA PTS cycle.
Sometimes i manage to solve the issue temporarily by turning off random settings in AMD control panel, but the issue always comes back after random amounts of time/restarting my PC
My specs: (Alienware machine that i picked the parts for myself, they built it for me)
amd radeon rx 5700 xt GPU
intel i9 9900k CPU
32GB ram
game is saved on NVME SSD
