what is video game optimisation and how does it get done well or badly?
In: 6
Video game optimization is the process of making a game run faster, more smoothly, have higher stability, or take up less memory for a given system running it without significantly impacting the user experience (like if you removed all effects) by increasing code efficiency or cutting back on processing-heavy aspects that the player is unlikely or unable to see. It can also refer to prioritizing processing power when the system can’t handle everything at maximum. Some examples are:
Making objects disappear if the player cannot see them, removing the requirement of loading and displaying them. They can also lower the frame rate or texture detail for objects that are distant and less able to be closely examined.
Using more efficient coding algorithms for the same task. Different approaches to coding things can have wildly different processing times because the coding languages in use are better at doing some operations than others.
Using less complex visual effects when other demands on the system are high to prioritize FPS or stability.
Using higher quality compression algorithms to make the installation download take less space.
A game with very good optimization can perform much better on the same system than a game with bad optimization, even if the first game is much more impressive visually. It’s a sliding scale, meaning that no game is perfectly optimized, and no game is perfectly unoptimized.
