Here's why:
* Minimum Requirements: Tomb Raider Underworld has a minimum graphics requirement of a dedicated graphics card, typically a GeForce 6600 or an ATI Radeon X1600. Intel HD graphics are integrated graphics solutions that are significantly less powerful than dedicated GPUs.
* Performance: Intel HD graphics are designed for basic tasks like web browsing and video playback. They often struggle to run demanding games like Tomb Raider Underworld, even at low settings.
* Game Optimization: Older games like Tomb Raider Underworld might not be optimized for integrated graphics. This can lead to low frame rates and visual glitches.
Possible Solutions:
* Lower Settings: You could try lowering the game's graphics settings to the absolute minimum. This might give you a playable experience, but it might also impact the visual fidelity of the game.
* Upgrade Graphics: Consider upgrading your graphics card to a dedicated GPU that meets the minimum requirements of the game.
Recommendation:
Unfortunately, playing Tomb Raider Underworld on Intel HD graphics is likely to be a frustrating experience. Upgrading your graphics card is the most reliable way to enjoy the game smoothly.
