My PC specs:
7600k @ 4.8 GHz (stable).
GTX 1080 Ti.
16 GB RAM.
GTAV loaded on SSD.
2560x1440 monitor, 60 Hz.
GTA5 graphics settings:
Pretty much everything on high/highest except Grass and PostFX (both on high). All advanced graphics turned off.
There's some stuttering in the grassy areas near freeway overpasses when I walk around w/ resolution set to my native 2560x1440. FPS is upwards of 100+ but fluctuates wildly and stuttering is pretty bad.
However, when I change the in-game resolution to double (5120x2880), I have a corresponding drop in FPS (down to the 60s-70s) but the game is smooth again.
I monitor my GPU/CPU usage in-game and it doesn't appear that my 7600k is bottle-necking my 1080 Ti. I'd prefer to play the game in my native resolution (2k) for the higher FPS, but the choppiness is unbearable. Thoughts?
