I run the game by pressing space then my game starts. Sometimes objects are not initialised properly. Some objects has wrong rotation. Some object does'nt show at all then i have to press escape key and again press space. After that all works properly.
Is there any way to properly load everything?

You could reset or manually translate your objects in a script.

I will try and revert. I thought of it  but this solution is not working.
I will check again (iobject reset).

Could you send a copy of your project, if you fail to fix this?

please check
i can send script but its also weird like 3drad

how much ram do u have, how much is game using and how much ram is free when running game?

There is no issue of ram
16gb ram
Rx 6700xt
11900 processor

there is issue with ram, rad is limited to using only 2gb, unless you use '4gb_patch', it also has ram leaks that grow with each level load, is why you need to monitor used ram of rad itself not system used ram
