It's an unstable basically 25~30. Exploration is mostly stable-ish. Combat is where it doesn't hold well. It doesn't seem to drop as low than 2, and the weird nature of combat makes it not a huge problem, but it's not super-smooth.How bad is performance? I really like the previous game but it didn't run that well.
In terms of image quality, they traded a dumb-ass sharpening filter for what you could call a « smear rendering » pipeline. I can see why some prefer that to 2, especially as they improved shaders and lightning. But the 540p base res shows. Everything feels blurry, even though TAA tries to hide it.
