This is a list of general-purpose optimizations for C programs, from the most impactful to the tiniest low-level micro-optimizations to squeeze out every last bit of performance. It is meant to be read top-down as a checklist, with each item being a potential optimization to consider. Everything is in order of speed gain.
Choose the best algorithm and data structure for the problem at hand by evaluating:
| #define CONCAT_2_EXPAND(A, B) A ## B | |
| #define CONCAT_2(A, B) CONCAT_2_EXPAND(A, B) | |
| #define CONCAT_3_EXPAND(A, B, C) A ## B ## C | |
| #define CONCAT_3(A, B, C) CONCAT_3_EXPAND(A, B, C) | |
| #define Vector_(NAME) CONCAT_3(Num, Vector_, NAME) | |
| #define Vector CONCAT_2(Num, Vector) | |
| #define num float | |
| #define Num Float |

| Can load easier and more indepth with https://github.com/Hydroque/DDSLoader | |
| Because a lot of crappy, weird DDS file loader files were found online. The resources are actually VERY VERY limited. | |
| Written in C, can very easily port to C++ through casting mallocs (ensure your imports are correct), goto can be replaced. | |
