GTA Online. Infamous for its slow loading times. Having picked up the game again to finish some of the newer heists I was shocked (/s) to discover that it still loads just as slow as the day it was released 7 years ago.
It’s parsing something. Parsing what? Untangling the disassembly would take forever so I decided to dump some samples from the running process using x64dbg. Some debug-stepping later it turns out it’s… JSON! They’re parsing JSON. A whopping 10 megabytes worth of JSON with some 63k item entries.
It’s surprising that this issue had never been considered worth it to be fixed by Rockstar. I do think 63,000 items loaded via JSON is excessive, but I don’t think it’s unreasonable given the size and scope of GTA online.
