Emulator freezing on Vulcan

Greetings everyone,
This is my first post on the forums.I have tried RPCS3 a couple of days ago and found out that whenever i switch to Vulcan the emulator freezes to a white screen. My PC specs are as:

CPU=i7 3770
GPU=AMD Radeon R9 290
RAM= Rip Jaws G-Skill 8GB 1600 Mhz

I just checked on the web my GPU supports Vulcan but the emulator freezes when i select it as an option.

Help required.

Thanks!
