I know my English skills are bad, that why sorry about that.
Im using default S2 0.5Z, but when i instaled z15 patch on my 0.5zm handling was different changed on keyboard. Can i get old 0.5 z handling on new patches, and how?
Thanks.

Can you tell what was the difference?

handling was very quick and hard to control

Try to play with some options in Options > Controls

Select Keyboard - stabilised and try to change Limit multiplier etc.

Here is more info.

I know that, i already at begining changed that, but handling is much different.
