1. Restore your vanilla Grand Theft Auto V files.
2. Download and extract the manual LSPDFR 0.4.1 version to your GTA V.
3. Download and extract the latest rage hook plugin to your GTA V.
4. Update all plugins, scripts, asi's, hooks (such as scripthook, advanced hook, etc...).
5. Run OpenIV. Go to "tools" then "ASI Manager" and ensure "ASI Manager" is installed as well as "OpenIV.ASI".
6. Use OpenIV to add the "mods" folder functionality.
7. Install all rpf related modifications via the mods folder instead of replacing the core game files.
8. if using ELS, make sure you have the latest version, disable AI els functions and lower the maximum allowed vehicles using ELS.
9. Set "Plugin timeout threshold" in the Rage Plugin Hook settings to 60000.
10. Use DirectX 10 (This fixed the "GFX D3D INIT" error I commonly recieved in Vanilla and modded versions of Grand Theft Auto V).
Other Tips:
Make sure all mods/plugins/scripts are compatible with your rig, LSPDFR 0.4.1 and your current Grand Theft Auto: V version.
When installing mods/plugins/scripts, skip existing files that are likely to be things such as advancedhook so you don't replace it with an older version.
Try LSPDFR 0.4.1 with no extra mods/plugins/scripts
