Lag and stutter when pressing keys or moving the mouse
Emily Wong
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.

Run the game as Administrator.
Also, I had such issue due to the DVD security from GTA.
Since GTA IV is a fairly CPU heavy game, check if it's using all the cores. While the game is running, alt-tab out, then go to Task Manager -> Processes -> GrandTheftAutoIV.exe -> affinity.
