Razer Blade 14 2014 GTA V Stuttering.

Hey

I played the game a few days ago and it was completely fine. I started it up today and there's stuttering every few seconds. I looked at task manager and the stuttering is exactly in time with a drop in CPU % utilization. So i think the CPU is throttling :/

Any help?

Thanks in advance
