After a while, my fps drop to 4-5, even 0, and stay that way. I have an Nvidia GeForge 840M, an Intel Core i7 and windows 10. The only graphic mods I have installed are a light texture pack and a mesh improvement (no morrowind rebirth, no huge cities overhauls, nothing that could have a huge impact my fps). This laptop has also a fully modded Skyrim and Oblivion. I also tried to install vanilla Morrowind and MSGO (to see the difference) and I always have 30 fps, with medium settings. I can safely say that hardware is not an issue here

I hope I'm not the only one.
Thank you in advance for your reply!
