Faster Bitmap C# or something else (to be fast as high quality games)

Question

Anyone knows how the game works with such high resolution, with such fps?

Answer 1

Its not about the language, its more about the technique.
Game rendering cheats/take shortcut a lot than 3D rendering, where as 3D rendering will focus on its quality and accuracy to max, game render focus on how fast they can be without much quality difference.

for example image quality will decrease or increase based on player's distance, a limited render distance, using low poly model for any inaccessible structure, 2D rain/snow.

They're also use their own rendering technique like raster rendering which really fast compared with ray tracing (original DOOM and some 3d render software)
And 1 more thing is usually its run in GPU which is better at rendering than CPU.

Answer 2

Taste do you know how slow Bitmap in C#?

Answer 3

Tbh, i never do any image processing in c#
But i did some research, it looks like its pretty slow. But there are some workaround to make it faster
