The following mods are special because they need to be installed directly into the game's Root folder, not through Mod Organizer 2.Use the Manual Download and follow the instructions provided for each mod.
Failing to install these mods correctly will result in issues.

High FPS Physics Fix
All-in-one solution for smooth FPS-unlocked gameplay, mitigates stutter and reduces loading times massively.Installation instructions
- Main Files - High FPS Physics Fix 0.8.11 (2nd file)
- Once the mod has been installed, double-click it in the left pane of MO2.
- In the INI-Files tab, open F4SE/Plugins/HighFPSPhysicsFix.ini
- Change only the following options[1]:
- Set DisableBlackLoadingScreens to true (line 37).
- Set PostloadingMenuSpeed to 3.0 (line 51).
- Set OneThreadWhileLoading to false (line 84).
- If you use VRR[2], set InGameFPS (line 58) to a number you can reach across the majority of the game[3], it has to be between 48[4] and refresh rate - (refresh rate x 6.8%)
- If you use fixed refresh rate (no VRR), set InGameFPS (line 59) to your refresh rate - 0.005 or fractions of your refresh rate (choose based on which is closest to your lowest FPS).
- If you set InGameFPS to a value higher than 60, do the following as well:
- Set DynamicUpdateBudget to true (line 291).
- Set BudgetMaxFPS to the same value as InGameFPS (line 310).
-
Do not touch other settings unless you know what you are doing! For example you should know that:
- AllowTearing needs to stay enabled, it's a requirement for VRR and won't lead to tearing during gameplay - the mod turns off V-Sync only during loading (making it faster).
- Enabling DisableAnimationOnLoadingScreens will freeze loading screens and any overlay you use, this is intended and will speed up loading by about 40%. You can enable it if you don't mind frozen loading screens.
-
You can check if you are using VRR by going to the Nvidia Control Panel if you're on Nvidia or Adrenalin's Display Settings if you're on AMD. If the G-Sync tab is missing from NVCP, your display doesn't support it or doesn't have the feature enabled in the OSD.
Nvidia users need to make sure that G-Sync is set to Fullscreen and that Display Specific settings are enabled, the Windowed option is problematic due to it being a hacky method. Both of the settings are wrongly named so they do not actually directly refer to the display method. - You always want your FPS capped by a limiter instead of being hardware bound, this will reduce lag and increase power efficiency. It is also less jarring for the player when visual smoothness is the same across all scenes.
- The VRR range on most monitors starts at 48, but it might also start at 30 or 1. You can check this on Nvidia's page or from your monitor's specifications.
