i reinstalled dx and cleared out amd drivers using DDU and installed 15.7.1 WHQL Drivers
but it is working.

1. During installing the game, did antivirus detect any false positive?
2. Do you have latest amd graphic drivers?
3. Disable your antivirus try reinstalling the game.
i have tried all of this but nothing seems to work, Here is a video showing a problem similar to mine.

The system you have should be enough for this game but not 1920x1080 resolution.
Try blocking the game in firewall and disable the internet and turn down your resolution to 1024x800 and keep graphical quality low, If this works then you can change the resolution to 1280x800 and graphical quality ...

My System Specs is:
Windows 8.1 64 bit
Gigabyte GA-880GM-D2H
RAM 4G DDR3
AMD Athlon II X2 245 Processor 2.9 GHz
AMD Radeon HD 7750.

and I was trying to play on (1920x1080) but all the other settings are low.
but i tried every resolution and it's still the same.

I Just Downloaded and Installed FC Primal and I started a New Game It Loads until the Loading bar Reaches 100%
and Then It freezes.
can any body help me.
