TW3MM has integrated merging functions (KDiff) for scripts that need to contain lines of code from different mod sources, which is pretty common when you start running a hundred mods. You can also selectively delete the compiled script merges that you make and re-merge them if you have issues in the script manager, which by itself would be enough reason to use TW3MM over Vortex. If the automerge causes a problem with compiling, it will tell you which file, so you can delete the automerge and selectively choose which of the two or three (or combination and order) of the mod script lines you need. TW3MM also supports prioritizing mod loading order, so things will be loaded in order and may prevent the need for some messy merging or file version selection. It also keeps a list of data files in your DLC folder, many of which are needed by mods in the Mods folder, which is what TW3MM primarily handles. There are some mods that need to be manually unzipped because they modify files in the bin folder, but I can count on one hand the number of these I use out of over 100 active mods. The only other piece of the puzzle is your My Documents/The Witcher 3 folder that contains input.settings, containing key bindings that some mods need. Here's a full installation guide for running The Witcher 3 with the full baseline of community patching as of March 2021

Start by deleting the extra terminating brace on line 313 and let us know how it goes. For modders reading this, some of these mods are pretty sloppy. On lines 1602,1603 and 1609,1610, change true to false and 1 to 0 and uncomment those lines if you actually need that. Those function calls should happen once when you start a new game, but that's a setting (UberMovement/Alternative Movement) you can change in the options menu and shouldn't require modifying or removing calls to the engine. Lots of things like that add up to weird unresolvable modding issues.

Since line 7091 has the terminating brace for the CActor class, it's a mismatched terminating brace somewhere in that class. Mismatched merges are common, especially with more complicated mods. The best way is to start from the top or bottom and read through it to find where that happened, or do that every time you diff so it's not so hard to find. Start by searching for comments ('//' or '/*') and that will show you where most mods begin and end. You have an extra } on line 1280 before the return statement for CalculateFinalAnimationSpeedMultiplier() . Delete that and it should work.

If you don't have a FreeSync or G-Sync capable GPU & monitor setup, both AMD and Nvidia have driver level solutions (AMD: Radeon Chill & Nvidia: Max Frame Rate). Traditionally everyone used RTSS (RivaTuner Statistics Server) before. Nvidia inspector can also tweak those settings for that brand.
