Developer 10tons Ltd. has announced that Neon Chrome was updated and the 4K support for PS4 Pro is now available.
The developers are excited that they were able to deliver true native 4K at 60fps for Neon Chrome! The game renders in true native resolution without any upscaling. They estimated that they would not hit any fillrate limits as the game was limited mostly by draw calls because of destructible environment. This estimate was quite accurate and the 4K performance is very good on the PS4 Pro. 10tons expects that many other similar games will gain 4K support in the future as it is relatively easy to do. You do need to have a certain amount of fillrate headroom when running on the original PS4 to reach 4K@60fps on PS4 Pro though.
Neon Chrome looks super sharp and runs silky smooth on the PS4 Pro. So if you have one, be sure to check out the game as well!
