The person who made the mod showed their specs and they had a i7-7700K and 1080 TI and they said it runs more or less stable at 90FPS all the time. I have a 2080 Super and a Ryzen 9 3900X and I can't get higher than 45 FPS outdoors.

I dont understand, I followed all the directions and disabled all the settings it said to disable or lower
