I'm having some issues playing GTA V, at 4k it normally is pretty smooth, recently I've had to knock a lot of settings down but still certain areas with high foliage the frames tank to 30 ish and it seems uber laggy compared to a lot of games at similar fps, this game used to run mostly max settings at 4k with my 1080Ti and Ryzen 1600 at 3.7GHz, can't seem to work out what th e issue is? Any ideas/
Performance has dropped over time, however turn grass to normal and retest as that is the killer even at 1080p. There is so much more content (20GB larger install size that on release) that it is slowing things down now... Even my 980Ti is struggling now and I have not changed settings in 3 years other than a processor change.
