I want to use Geyser plugins but I need to know do I need a power full computer in order to run a validator or RPC node? if yes what are the hardware requirements ? The estimated requests per month is 20 million.

Hi I am developing a game and as It's obvious the game is going to need WebSocket in order to be live, so i have been researching and found three ways to do It, But I got questions:

1. TS code is the first and easy way to do the subscription but what are the limitations for this ?

2. Quiknode
