MWSE VS openmw

The alternative is to install Morrowind Code Patch, Morrowind Graphics Extender XE, and the latest nightly build of MWSE. There are a number of benefits to this approach, the biggest one being that there are a lot of MWSE mods that people like which aren't available to OpenMW players. For me, the primary draw is that Morrowind Code Patch has some features that aren't available to OpenMW players (In particular, the option to have female Argonians wear male armor is so blindingly obvious to me, it drives me nuts playing without it).

If you aren't using OpenMW, you will want Morrowind Code Patch, Morrowind Graphics Extender XE, and (maybe) the nightly build of MWSE. MCP and MWSE are requirements for a lot of mods -- depending on which mods you use, the version of MWSE that comes with MGE XE may be sufficient, but others may require a newer version (the "nightly build"). Using mods without either of these two set ups (OpenMW vs MCP + MGE XE + MWSE) isn't really worth it imo -- they're the only way to get good graphics, and one or the other is a requirement for many good mods. My suggestion is that your first step should be to pick one of the two -- OpenMW will be easier to set up.

Greatness7 posted an updated esp for the mod and a Lua version. Apparently, a newer version of MWSE broke the original mod. You can get both the updated esp and the new Lua version here: https://github.com/MWSE/MWSE/issues/116

I'm trying to find the documentation for functions to do LUA scripting in MWSE, but my research keeps leading me back to this website or some page relating to it which says the pages don't exist.

Kind of a long shot, but also try updating to the latest version MWSE. (The one in MGE XE is a bit outdated, works with most mods but not all.)

OpenMW - The Elder Scrolls Morrowind clone. C++, OpenGL

I downloaded the build via openmw-0.48.0-Linux-64Bit.tar.gz, it runs very well, but whenever I add the game as a shortcut to steam, the performance fumbles, I get around 25-30 fps at best, and I tried to experiment a bit and search more on the internet for a solution before posting in here, but nothing have helped as of yet. If there's someone who worked it out, please share it with us.

They haven't been great at announcing progress lately, but it is ongoing. The GitHub page is showing plenty of commits still coming in: https://github.com/OpenMW/openmw/commits/master

It's open-source and anybody can take a look at the code. Trading and Speechcraft changes are detailed here and here, respectively.

There's also a fan made open source game engine recreation for it called OpenMW that makes it a dream to play on anything from an android phone to a Mac to a PC.

On the main openmw config, there's different files listed https://github.com/OpenMW/openmw/blob/master/files/openmw.cfg

Download this .dmg and install this version of OpenMW. I pulled it straight from their GitHub and it is the same one I use. Try the process with this see if it helps?
