Common Options : Enabled, Disabled

Details

Many high-end graphics cards now require an IRQ to function properly. Disabling this feature with such cards will cause improper operation and/or poor performance. So, make sure you enable this feature if you are having performance or stability problems with your graphics card.

However, some low-end graphics cards don't need an IRQ to run normally. Please check your graphics card's documentation (manual) to confirm. If it states that the card does not require an IRQ, then you can disable this feature to release an IRQ for other devices to use. When in doubt, it's often best to leave it enabled unless you really need a free IRQ.
