pps english is not my native language

edit: I allrady trued clean reinstalling video drivers, beta and stable version whith no efect

I'm having a similar issue , haven't made it past the first 20 seconds of the tutorial and it stutters and eventually locks up on a black screen.
Also i'm getting really bad flickering on scenery.

At first i thought it was gfx settings related but ive tried almost every combination i can think of and no change.

OS
Windows 7 Ultimate x64

CPU
AMD fx8320 black

GFX

ok so i found the solution to this problem, i changed the gpu core clock from 1000MHz (the stock Gigabyte value) to 925MHz (the stock amd value) in radeon setting mud runner profile, also for those who running crossfire, run game in windowed mode or disable crossfire in radeon settings
