The obvious thing is performance. Vulkan runs better which means more fps but it really is a small amount. Vulkan is supposed to be more finished and constantly updated vs DX11 which is now supposed to be replaced by DX12 (though it seems unstable in most games).

AMD states that "Vulkan supports close-to-metal control, enabling faster performance and better image quality across Windows 7, Windows 8.1, Windows 10, and Linux. No other graphics API offers the same powerful combination of OS compatibility, rendering features, and hardware efficiency."

Yes, there have been a few people who have become rich solely from casino winnings. However, it is important to remember that these cases are extremely rare. The odds of winning a large sum of money at a casino are very small, and most people who gamble will lose money in the long run.

However, a few individuals are able to defeat the odds by using systematic apps and algorithms. These individuals may make a fortune on betting but even so, they rarely become millionaires through betting alone. Betting is not a form of investment and odds are always against the individual who engages in betting.
