I Downloaded GTA V And I Keep Getting This
It might help to post more than just a video of your desktop with GTA V barely running. Describe. What's happening? Where did you download GTA V from? What are your PC specs?
From your resolution I think your specs just aren't good enough, but it's hard to judge when there's no information
The Installation Help & Troubleshooting forum is a better place for this, by the way.
