Any mainstream processor released from 2014 onward (Intel Haswell / 4th Gen Core or newer, and AMD Ryzen) natively supports AVX2. Upgrading ensures compatibility not just with Uncharted 4 , but also with an increasing number of modern PC titles that now require AVX2 as a baseline system requirement.
| CPU Generation | AVX2 Support? | Expected Experience | | :--- | :--- | :--- | | | No | Playable via SDE/Fix, but expect 30-40 FPS on Low/Medium. | | Intel 4th Gen (4xxx) & newer | Yes | Game works natively.
