Ok just incase anyone comes across this thread what worked for me was the opengl thing. I will paste it below. Credit to Kaomech.
LAG/FPS issue NVIDIA PEOPLE!: I met someone in game who mentioned this and despite unreal3 engine not supporting this whatever it changes...made my game beautiful!
basically you go to your games folder
Install > Steamapps > Common > Bless Online > Engine > Config > BaseSystemSettings.ini - open in notepad
hit CTRL+F - type opengl youll get a line that says opengl-false or something like that
make sure you have it exact its case sensitive... save
now open down bottom right Nvidia Control Panel > Manage 3d Settings
set it to Bless.exe go down to OPENGL and select your graphics card from the drop down menu and save it all ...
RESTART YOUR PC and begin playing... the first time i logged into the game after this it was choppy for a good 5 mins then smooth as day ever since...
made ahuge differnece for me ... although since I have;
reverted back to compatibility mode back to window 10 / i have told steam to verify all game files again ...
Since doing this my game hasn't cut out every 60-120 mins of play
