10 Gigabytes, yet the memory still hasn't run out.
I feel compelled to correct this...
The size of the game has no baring on how much RAM it will utilize. You have games like COD or Battlefield that use somewhere close to 500Gb.
A memory leak has nothing to do with the size of a game. It's about the number of objects being held in RAM. RAM is short term memory and is frequently being addressed; contents are being loaded and unloaded from the RAM constantly during operation of software. A memory leak is when objects are not being properly removed RAM for various reasons, as a result, eventually the game or software can no longer allocate space in the RAM for necessary functionality, and as a result, terminates or will begin using virtual memory (which is when it starts using your hard drive like RAM, but your hard drive is a lot, a lot slower than RAM - even the fastest SSDs are no where near as fast as RAM)
I feel like it would benefit discussions to respond to topics you understand. Responding to topics you may lack knowledge about can just lead to derailment or worst case scenario could even spread false information. We always appreciate your input, but let's just make sure your contribution is meaningful to the discussion - especially when you have admitted yourself several times that you don't know much about computers.
