Interesting read on how GTA Online player t0st got elbow deep into disassembling GTA Online to fix its poor loading times.
After taking a minute to load the common resources used for both story and online modes (which is near on par with high-end PCs) GTA decides to max out a single core on my machine for four minutes and do nothing else.
Disk usage? None! Network usage? There’s a bit, but it drops basically to zero after a few seconds (apart from loading the rotating info banners). GPU usage? Zero. Memory usage? Completely flat…
What, is it mining crypto or something? I smell code. Really bad code.
One of the culprits as he found out: a poorly-implemented JSON parser locking up a single CPU thread as it tries parsing a 10MB JSON file.
Fascinating to see how he’s practically touching in the dark, yet still finding clues and being able to solve them.
Let this be a reminder to not take common tasks/libraries for granted, and also question them when running into performance issues.
