How to reduce the loading times
The guy that came up with the discovery about the loading times (search this: "How-I-cut-GTA-Online-loading-times-by-70")
has compiled the dll for download, search for: "GTAO_Booster_PoC"
It can be used with cheatengine, by making a script like this:
[ENABLE]
{$lua}
injectDLL([[D:\GTA5\Universal.GTAO_Booster.dll]])
createTimer(500, function() memrec.Active = false; end)
{$asm}
[DISABLE]
Hope this can help someone who has no idea how to try the loading times booster.
Another way to inject the dll is by opening the "memory viewer" window in cheatengine, and pressing "inject dll" in the drop menu "tools".
Thank you for the share but mod menus typically load quickly anyways.
