Hello,
Change the plugin timeout threshold from 10000 to 60000 in the RagePluginHook.ini file and disable Main.PreloadAllModel in GTAV/LSPDFR -> LSPDFR.ini.
And rename the LSPDFR folder in /Plugins to _LSPDFR.
OR
Second thing I would suggest trying is turning off ambient events. To do that, follow these steps:
1. Go to your GTA 5 Main Directory.
2. Find the file titled: LSPDFR.ini. (Will either be in the LSPDFR folder or Plugins folder).
3. Scroll down to the line that says Max events for ambient spawns.
4. Change that to 0.
5. Save and then launch RPH.
Let me know if one of these helps!🙂
