“it just maxes out the ram and then does nothing.” is absolute nonsense. The programs need memory to operate.

If your RAM is maxed out and the programs seem to operate just as fine, the OS is doing something behind the scenes, it’s just a matter of what that something is. And memory swapping / virtual memory is a well-known method of alleviating RAM overuse, at the cost of murdering your SSD/HDD lifespan.
