no, I've always played on 32 bit and now the client automatically launches the 64 bit

Hello Usysuk84.
Is there any specific reason for using the 32bit executable even though your windows is 64bit? Are you experiencing any issues on the 64bit which are not present on the 32bit version?
Regards,
Geez

Yes
and how can I fix it

Hello Usysuk84.
Could you try to describe which issues are you experiencing on the 64bit executable compared to the 32bit executable?
Regards,
Geez

the problem is that I can't play the game when I was running 32 bit, fps was over 60 and when it started to run 64-bit was 15 fps

Hello Usysuk84.
Do you still have the issue with the low fps on the 64bit executable even now? Are you using any launch parameters? Have you tried to remove the contents of your C:\Users\*username*\Documents\DayZ folder to see if it has any effect on the issue? Have you tried to verify the game cache in Steam?
Regards,
Geez

Yes I have a problem with fps on a 64 bit
I don't use launch options
not helped when you run a specifically 32 bit version, it crashes when entering the server and runs the 64 bit

Hello Usyuk84.
Can you try to record videos for us, comparing the fps on the 64bit version and on the 32bit version? You can currently launch the 32b version by creating a shortcut of the DayZ_BE.exe on your desktop and adding the line "-exe Dayz.exe" (without the "") into the target window (Right click on the shortcut, go into properties, select shortcut tab and find the target window - do not remove what is already in the window but add the parameter behind).

I don't understand how to do it? I have windows 10

Hello Usyuk84.
You have to navigate into the steam folder where your game is installed, there you need to create a shortcut of the DayZ_BE executable (by right clicking on it and selecting create shortcut). Once you have this shortcut created, move it to your desktop (or any place you would like to have it at). Then, you have to right click on the shortcut you just have created and select properties. This will open the properties window, with the shortcut tab being selected as default. In there, you can find several columns, the one you are looking for is called "Target". The target column contains a path to the executable which the shortcut is refering to. What you have to do is click into the window and add "-exe Dayz.exe" right behind the path to the executable (so for example, the target looks like this now: "C:\Program Files (x86)\Steam\steamapps\common\DayZ\DayZ_BE.exe" -exe Dayz.exe). Once done, all you have to do is press apply/ok and then launch the game through this shortcut.

Geez

thank you to all helped

Hello Usysuk84.
If it is not a problem, we still would like a video comparison of the two versions on your computer, as the 64bit client should not have the issues you are describing and we would like to gather as much information as possible.

Geez

Имею такую же проблему с падением ФПС на x64. Постараюсь записать видео и выложить в ближайшее время.

Hello again.
There have been some tweaks released on the experimental version. Can you please try the 64bit version on the current experimental and let us know if the problem with fps being worse than on 32 is still present?

Geez
