Zoom problem!
 

Hi everyone. I'm playing CS for long time and I had no problems, but recently...I don't know what happened... I was going to play, started CS and I noticed that FPS was low... Chaked forums and found console comand to boost it up (it was all laggy). But there still was a problem... When i zoom with scout or awp (and others zoomed guns) my crosshair gone crazy... I attahed image , so you can see what I'm talking about... It's ok with the crosshair... I think it's problem with CS... Please help me.

Thank you,
Plytas.
