4K Gaming: What Can PC Learn from PlayStation Pro?

Native output is king, but here is an argument that certain graphics tricks utilized by consoles to overcome modest hardware should see greater use on PC. Techniques such as checkerboarding and dynamic resolution would provide more flexibility for gamers with high-resolution displays but weaker rigs, or for those who want to prioritize image quality versus performance differently. Nothing wrong with more options, I say, even if "fake" 4K is blatantly worse looking.

...when it comes to rendering to a 4K display, a native framebuffer is obviously the most ideal way to go, but we strongly recommend experimenting with internal resolution scalers and the CRU tool if you feel performance could be improved. Based on developer documentation we've seen, Sony's internal tests found that sub-native resolutions at 1800p and higher still hold up well on today's 4K screens, and our tests on a 32-inch 4K monitor and a 55-inch OLED screen bear this out. 1800p is effective, but there are other options: a 3456x1944 resolution amounts to a 90 per cent scale on each axis, adding a good degree of wiggle room to your GPU in improving frame-rates, while still looking great.
