I am trying to play a browser based game on Chrome. My system runs Ubuntu fine and is a new laptop. The game gets choppy when I play. How do I allocate a little more memory to Chrome so I have some more browser-power to play this game?
Unless you've explicitly
If you have a small amount of RAM (no more than a few gigabytes), you could add more, but realistically a single browser game shouldn't be eating up that much.
Otherwise, there's nothing you can do to allocate more memory to it, other than patching the Chromium codebase to use more memory :).
In short, I doubt lack of memory is the reason for choppiness (it's probably CPU-bound, or GPU-bound if the game uses WebGL). But fixing that is a different question.
