Lag and stutter when pressing keys or moving the mouse

grand-theft-auto-4pc

So, I have all the recommended specs for GTA IV:

  • Windows 7 Home Premium 64bit
  • AMD FX-4100 Quad core at 3.6GHz
  • 8GB of RAM
  • Radeon HD6450 512MB

More than enough to run the game, but whenever I load it up it will stutter every time I press a button or move the mouse.

Any answers would be much appreciated.

Best Answer

Run the game as Administrator.

Also, I had such issue due to the DVD security from GTA.
