Full HD — max settings
When you see two FPS numbers, there are two common but different ways to show the difference:
This compares the slower card to the faster card.
Example: (21.7 ÷ 38.3) × 100 = 57%
This shows how much more the faster card performs compared to the slower one.
Example: ((38.3 - 21.7) ÷ 21.7) × 100 = 76%
You naturally think: "If RX 6400 is only 57% as fast, then GTX 1660 Super should be 43% faster" — but that's incorrect.
The "76% faster" is measured against the slower card, not against the faster one. So both numbers (57% of and 76% faster) are mathematically correct at the same time.
