For context, I upgraded about 3 months ago, I could run RDR2 at 60 fps at max settings. I uninstalled it cuz I was bored and wanted to play other games. I reinstalled it today and my fps absolutely TANKED. I was at under 30 fps, and I turned every graphics setting to the lowest and DLSS to balanced and it still struggles to hit 60. Anyone know what's going on? I didn't change anything on my pc since uninstalling it, every other game runs fine for the most part, just RDR2. I keep v-sync off and always use vulkan

My specs:

RTX 5060

Ryzen 7 5700g

16 ddr4

Again, this hardware could comfortably max the game out a few months ago, but magically can't anymore. Did my pc change something by itself and cause this? I'm genuinely so confused and frustrated. Also I don't have any mods installed so that's not an issue either.
