What ICC color profile do you use? do you use a driver setting like NVIDIA digital vibrance? what DPIs are you using? Are you using font antialiasing? if so, what font hinting setting are you using? are you using subpixel ordering? What CPU frequency scaling governor setting are you using? What power setting did you set for your GPU? NVIDIA has Powermizer settings which have adaptive clocking for the GPU and there's a GUI control panel for it that comes with the driver. Most of what you've mentioned here sounds like you misconfigured your system (e.g.: wacky fonts). Default settings often do not produce the problems you've mentioned. If you have a HiDPI setup like a 4K screen, simply set your resolution to 4k (3840 x 2160), scaling to 2x, 96 DPI and get a proper font of your liking. You can even get the fonts used on Windows if you install the TrueType font file (I think "Segoe UI Variable Regular" is the font name you would be looking for), with anti-aliasing y hinting set to Slight.
