x32 client

How can i launch x32 client instead x64? Is there some settings in launcher to do that?

 

Actually there is a way. Follow the instructions carefully:
1. Go to your Black Deset Online folder
2. Rename the bin64 folder to bin65
3. Find the bin folder and rename that to bin64
4. Open the previous called bin folder, find the blackdesert32.exe and rename it to BlackDesert64.exe
5. Start the game normally through GamezBD Launcher
It will run the game in 32bit. You can double check the task manager just to make sure. I wouldn't recommend using 32bit, there is zero benefit in doing so.
