Hey I realized that process lasso isnt working for BDO anymore. Do you guys have the same issue?
Please check if your settings for BDO process are properly applied to "actual" CPU affinity for example or I/O priority.

It is the new Anti-Cheat blocking it.

It needs to be fixed immediately. R9s get like 50% less framerate because of this.

yea its not working :(  Process Lasso is not a cheat. This need to be fixed asap !

Rofl the RBF crash is happening to me now because no process lasso...

Please fix this it is making it unplayable.

Few weeks ago, My CPU upgraded into AMD Ryzen 9 5950X and Installed a Process Lasso,
Then set a BlackDesert64.exe's process affinity as use only single-CCX and physical cores. (8 Core)

For a better and stable framerate.

Reasons to some people uses Process Lasso and Problem is the BDO Client doesn't handle well a HT/SMT for a really long time and still doesn't fixed in 2021.
Normally, In other game, Enabling HT/SMT increases framerate, but some games that has a outdated game engine and bad coding decreases framerate by Enabling HT/SMT... (Espically Ryzen CPU)

We just want to improve into a modern game engine designs that handles HT/SMT well in BDO :/ 

Yep,i want to be able to set BDO at realtime priority also.Seems it isn't happening ,so unless you are runing last gen threadripper,and 3090 we are at disadvantage ,in this "fair game environment" game .....Isn't that great?

Ok ,i want to be able to set BDO ,with higher priority back !Last night got disconnected 5 times while auto-pathing on a horse,and playing other games in the background.Game just dissapears,no crash to desctop ,no nothing it just closes it self,the only way i recognise it ,because i stop hearing the horse  in the background.This is rediculous !

use parkcontrol untill lasso gets fixed

Seems someone found a workaround

Currently at work so I cannot try it myself.
