AMD drivers are feeling a bit hit-or-miss right now. Things seem to be improving overall, but it feels like fixing one thing just breaks something else.
For instance, certain games (atelier Ryza) that ran perfectly fine for me last year won't even launch on adrenalin 2020 drivers.
There are also some things I just can't wrap my head around. Right now, I'm playing Far Cry New Dawn. I've got a Sapphire nitro + 5700 XT. At 1440p resolution (using a mix of ultra/high settings), I'm averaging about 70fps, with dips below 50 in some... "demanding" areas. The ceiling is around 90-105fps.
On the other hand, a friend using a standard RTX2070 gets an average of 100fps at 1080p with everything on ultra; he sees brief dips to 60fps and hits a ceiling of 150+ fps. And look, I get it, 1080p isn't the same as 1440p. It shouldn't be. But for me, it is. No matter what resolution I set, the fps stays the same. Even at 720p scaled to 50%, I get the same fps as I do at 1440p, except the image looks grainy as hell. 😬
Maybe it's the CPU (2600X) or just poor optimization, but still. It's bizarre.
