Hi, I think I'm in the right place for this problem. I did post asking for help on a mainstream gaming site but didn't get an answer, so here's the 'copy/paste' of my issue: I'm having a few problems with certain types of mods that I hope someone can help me with: If I download a mod that adds a building to the game then I get massive fps spikes when in the area of said mod. It can lead to the game crashing to desktop, so I've had to remove EVERY mod that adds buildings. I got a mod that adds carriages to the smaller towns/village which, since I play with 'Total realism' mod and don't want to use fast travel, was a mod I really, really, wanted. I've also had problems with mods that re-texture wildlife. It was easy to work out which mods were causing it since it would stutter when I was near water (mudcrabs) or out in the open (Rabbits hidden in the grass). Once again, I'd get crashes. I've never had issues with the big HD texture packs, or some of the smaller ones. Nor have I had issues with mods that change gameplay. Playing at 3.6ghz, 4gb, and GTX470, High Settings, and don't have any problems with building or areas in the vanilla game. I really can't work out what might be causing this, as other people don't seem to suffer the same problem (based on Google searches I did). If there's additional information I need to give then please let me know. Thank you for your time reading this. Sorry if this is in the wrong section.
