Gta 4 Missing Shadow setting
This bug can be fixed by updating to Patch 8 for GTA IV and Patch 3 for EFLC. From the download page for the Patch:
Fixed a bug that restricted settings changes when using modern video cards.
If you are using the Retail/Disk edition, click here for IV or here for EFLC to download the update. Just open the file and follow the instructions.
For the Steam edition, it should update automatically. If the game is updated and you are not running Patch 8/Patch 3, check the integrity of the game:
- From the Library section, right-click on the game and select Properties from the menu.
- Select the Local files tab and click the Verify integrity of game files... button.
- Steam will verify the game's files - this process may take several minutes.
