It appears the ROG CPU-Z build has been updated fairly recently, such that the interface is presented in a modern flat design, lacking most design elements intended to give the perception of depth. By contrast, the ROG version of GPU-Z looks quite dated, especially when viewed side-by-side. The current version sort of reminds me of when i look back at old screenshots of the earlier iPhone versions.. one glance and you know you're looking at iOS 5 (maybe android shows something similar, idk). Obviously this is a cosmetic issue and thus not imperative it be addressed immediately, but it would be a welcomed change if the dev team were able to do a small rework of the UI to give it a more flat design with sharper edges. Also, I know that TPU is responsible only for GPU-Z and of course I am under no illusion that the dev team are under some sort of obligation to make changes or honor every request. However, I thought I would raise the issue here, see what comes of it, and hope for the best. It would look pretty nice, though, wouldn't it?
All of this being said, I really appreciate the utility purely from a utilitarian view. Many thanks to the dev team for all the time they donate for its continues development.
