Placebo for sure, because framerate issues encountered in city was completely solved well before the 1.08 patch, and without disabling any graphical features. I remember that quite well.
...same for either performance or deformation IMO... both feel basically the same as before in all 3 versions of the patch. with deformation and parallax mapping off, I see no genuine frame rate improvement.
This was absolutely not this case for me with the PS4 version. There was a very clear performance improvement with the 1.08 patch. Speeding through downtown Los Santos resulted in frequent and noticeable frame drops before 1.08, whereas it is now very smooth. It's so much easier to race through traffic as a result. Huge Difference.
Yeah, seems like the deformation fix has had no negative effect on the framerate. I would assume that a forthcoming parallax occlusion mapping fix will tell the same story; they're just bugs, separate from the imo apparent optimizations.With deformation back on, I see no difference in amount or rate at which deformation occurs.
