Assuming you're talking about a PS4 Pro because you're looking at 4K, you can still enable both Boost Mode and Supersampling on the Pro to improve framerate and image clarity, respectively (the system says that these can introduce some incompatibility, but I've never run into any issues with either). To be fair, Supersampling is only available on resolutions smaller than 4K (possibly only 1080p). Therefore, I only get to use this option when I play my Pro on my non-HDR 1080 screen, and, as a result, my sample size with this feature, in terms of glitches, isn't as large as my sample size with Boost Mode. Regardless, I have yet to need to turn it off, and I do think it can help quite a bit with games that support higher resolutions.
