Hey guys

I've been playing Skyrim for the last couple of weeks on my new gaming PC. I have quite a bit of gameplay now, level 20 now with no major issues. I have been trying out mods here and there with no issues. A couple of days ago I installed a a few mods. A few quest mods, and a few minor things here and there.

When I went to play Skyrim it started with a CTD ten seconds into most saves. I uninstalled my new mods and sorted my load order using LOOT.

Now the CTD has stopped but the game's performance is abysmal. It now suggests me playing it at a lower resolution. I've been playing Skyrim with an ENB and 2k with some 4k textures with no real performance issues. I then used the 'clearinvalidregistrations' function of SKSE with no success.

All my other games are performing perfectly well btw.

Anyone have any idea what could be causing the issue?
