Nope, doesn't make an appreciable difference. Maybe gets me another 5 FPS, but still.
There's still an issue, and it's NOT with my system, it's a compatibility issue with the 3000 series GPUs. Otherwise I'd be able to get higher FPS on the same settings than my R9 got.
There's zero difference between 1080p and 1440p. Both for For FPS and for CPU/GPU usage.
The game is NOT leveraging the 3000 series GPU. The 7DTD issue isn't bottlenecking. It's a programming/coding/optimization issue somewhere. Otherwise there would be a performance increase, even if it's not a huge one.
