Just some feedback:
 
Please provide some way to scale/increase the OSD font size. This feature is almost useless on 4k monitors. You can't read anything without being 1 foot away. I have a 27 inch 4k monitor. I sit about 3-4 feet away. I can't see the text at all. It doesn't scale / follow windows 10 hi DPI scaling setting. Honestly, that's not even the problem. Just let us choose a font size and the problem will solve itself. Everyone will be able to go as big or small as they like. 
 
It's the small usability details that make software great. If it's not usable, It doesn't matter how awesome the tech is. I use this for checking FPS and frametime on games and videos while using potplayer + madVR to tweak upscaling to 4k. It gets old having to squint to see if the settings are too high. I've been squinting since rivatuner stopped being used by you guys. I thought you would addresss it eventually, but that doesn't seem to be the case. Please address this. My eyes aren't getting better as I get older.
 
For reference, I use 200% scaling on windows 10. This translate to 1920x1080 resolution for scaled items while using 3840x2160. For those wondering why I'd get 4k when my eyes suck, I can tell a difference in games and even things like netflix 1080p upscaled, and you can turn anti-aliasing off completely or down to 2x.  Higher Resolution > AA for quality images without jagged edges. AA is only needed at low resolutions like 1080p.
