Hi guys and girls!
Since i didn't saw any thread on it, i'm coming here to say that the Skyrim Memory patch from Sheson was ported to "NVSE 4.2b4". It didn't work exactly in the same way but it's very simple to activate.
All you have to do it's this:
Open the "Data" folder of FNV, then go to the "NVSE" folder and if it doesn't exist, create a new text file and name it: "nvse_config.ini" (Not in the "plugins" folder but in the "NVSE" folder!)
Open "nvse_config.ini" and add those lines:
[Memory]
DefaultHeapInitialAllocMB=400

There is not many feedback for it but it seems to work, since i activated it, i had less crash. In conjuction, you can use this mod:
"Zan AutoPurge Crash Protector - New Vegas Edition" http://www.nexusmods.com/newvegas/mods/49319/
It's useful if your FNV get slow after playing 1 hour or more. I had this problem like many others and this mod help me a LOT with that. It has an MCM menu and it's fully configurable. Don't set the purge time too tight because it could break some active scripts (Nevada Skies is an example). The default settings works good for me.
And, that's it! Tchuss!
