So after not having played Grim Dawn for a good while, I got the itch to try out an AAR Spellbinder. But when I booted up the game, the framerate was not the silky smooth 60 FPS that I had played more than 200 hours with. It seems like 30 FPS or so. It feels so slow, especially when turning the camera, but it isn't stuttering or skipping frames. It's still playable, but the sluggish framerate is annoying and fiddling with the video options doesn't seem to be doing anything. Does anyone know what's causing this and how to fix it?

I know you said it's not stuttering, but see if anything suggested here helps
