I am currently working on the concept of a game, but I'm running into some problems.
For the game, I'd like to be able to directly change pixels on screen. However, all approaches that I tried so far resulted in my programs being rather slow, even without game mechanics attached to it.
Since a lot of games are also running on 60 fps with changing every pixel, you would expect it not to be hard to achieve such frame rates, if you could find the right way of changing pixels. The speed that I am aiming for is also at least 60 fps (if possible even on low-end hardware)
What is (or what library has) the fastest way to achieve this? It doesn't really matter what language the library is for, as long as I can get those high speeds.
