Performance Load Problem in Cubase 7.5 64bit

Hello everyone. (sorry for my bad english)

I just checked the other posts and none of them was useful.
When i open my cubase 7.5 32 bit everything is working good- the sound is great and the performance overload is good until the project is to big. and thats normal. But when i open cubase 7.5 64 bit, there is a huge problem. the sound not good because of the Performance load. The meter show me full use, and i cant work on the 64 bit for that reason.

That problem appears even in the minimal project, when i just load one channel with kicks for example.

I have Windows 7, 64 bit, i5, 2.5 GHz, And 8 GB RAM.

Someone can please Help me?!?!?!?

Got same problem but with Cubase 8… Waiting for any suggestions.

@Bentr: Which 7.5 version are you using?

I find out, that when I open a project with google chrome working, then performance meter reaches peak and cubase crusches imidiately after pressing “play”. When I close chrome and re-open project everything works fine.

Nope, it doesn’t matter. Problem is back…:frowning:
