Recently, I have been having a stuttering problem while play Fallout 4. Now, I admit my GPU could be better, but I found turning off AMD's Catalyst Control Centre via the task manager solves this issue.

• AMD Radeon HD 6670
• AMD FX™-4100 Quad-Core Processor (4 CPUs), ~3.6GHz
• 8 GB RAM

I am amazed the game even played on 6670.

Yeah, so am I. I will be investing in a better GPU soon.

Thnaks for the tip will try to see if shutting it down will fix other graphic error...fullscreen mode and not launching in my case

I was using a 6870 up until last year; fast hot and lound
