An ideas why I'm getting better performance at DSR'ed 4k than at native 4k?
I found a pretty good mix of settings that at 4k downsampled to 1080p give me 53-60fps on a set of 970s.
-Hairworks off
-SSAO instead of HBAO+
-Shadow Quality to Medium
-Foliage Range to Medium
-No AA
-Most Post Processing effects Off except Bloom and Light Shafts
-Everything else set to Ultra
So I figured...time for my 4ktv to shine. Its a Panasonic AX800U which is connected through Displayport at 4:4:4 Chroma Subsampling.
Well...at the exact same settings and obviously the same resolution, it tanks to about 31-45fps. An annoying stutter fest.
Can't be VRAM usage.
Isn't native 4k suppose to be less demanding than 4k DSR since the GPUs are not doing any downscaling?
