Force REshade IMGUI to rebuild font atlas for given size?

The overlay text for FPS and/or Clock is really blurry and low-quality. This is common issue with anything that uses IMGUI, they font system is so terrible only like 0.00001% programs and tools that use it can get it right and only after years of fixing. Does anyone know a way to force rebiuld atlas for given size?

Changing only the OSD text size does intentionally not resize the font atlas, so that the rest of the overlay text is rendered at the correct scale/quality (not undersampled/oversampled), since the font is shared. If you want to get high quality OSD text, you'll need to leave the OSD text scale factor at 1 and change the size of the "Global font" setting, which affects all text and which will force a rebuild of the font atlas at the desired size.

That is what I have right now and results are fairly poor.

I'm also having this problem and am aiming to change the OSD text size but haven't seen the results yet. Does anyone have a better solution? 

Also, since changing Global Font also changes well, global UI font this is not an applicable solution.

At 1080p frame I'm contempt with 16px font in the UI, but I was OSD to be bigger, up to 32px or more. Have you ever tried to use Reshade UI at 32ppx for 1080p rendered frame? Very funny experience.

Is there a reason OSD scaling cant be NN/interger? A lot of work implementing it?
