I recently bought a Sony PXW-Z190 I'm recording with Frequency:59.94 , Codec: XAVC-L and Format: 1920x1080 35. When I load it into Vegas 14 my preview window is very stuttered playback. I have tried changing the preview quality with not much success.
Any feedback would be appreciated, thanks
Are the project properties the same as the file(s)?
You've told us something about the nail, but you've said nothing about the hammer that you're using. Give us a hint about the hardware you're using to pound that video into submission.
No problems here VP14 on a modest quad.

Even though you have 8 cores, the clock speed at 2.13 GHz is slower that the 4GHz processors that are common these days. Memory bandwidth may also be a limitation. I can't say much about the Quadro 4000.
It's probably time to start looking for a newer system to process your new source files now that it's 2015.
My modest quad is 1.9GhZ, and it previews XAVC-L perfectly. It's not exactly a demanding format.
Is your project set at 8 bit or 32 bit? Show us your properties. Are there ANY fx on the timeline?
Here are the properties
"I'm recording with Frequency:59.94"
You report that your source media is twice the frame rate that you have set in the Project Properties...
... and you have Smart Resample enabled.
Set Resample to None and see if that improves your preview performance.
Also, if all your source is progressive, it's not necessary to set a Deinterlace Method.
Here's what happens to my preview when I duplicate your settings.
Here's an example of my preview when I match the frame rate with Resample Disabled.
