I assume it's because the game can run DX11 or DX12, it's accidentally forced a DX11 only setting onto the game, when enabled.

Is it worth expanding the porch settings/blanking if i cant do large steps?
Is there a math behind it to make it only useful in certain combinations, or just go as high as it allows?

You shouldn't need to increase the blanking. That would use more bandwidth. Horizontal values are usually a multiple of 8, but there's no technical restriction from using any combination of values. None of this should affect the bit depth or fast sync, so this seems like something GPU-specific.

Sorry, Working on two seperate issues there
Being VA panels they have some smearing and while i can use CVT-RB2 and get 10 bit, i notice more of that black smearing - so i'm working on the various options to see what works best.
I was trying to figure out the highest bandwidth that gave me 10 bit without just raising values in increments, but also didnt want to waste time if i raised the wrong value or the display tech simply doesnt work that way.

I'm exploring what the display(s) can do, so i can pick the one that works best for me overall - They have amazing 2D quality, but the default settings had extremely bad smearing of black and magenta, and Gsync flicker.
Magenta smearing was only fixed with the colour profile of the LG display (worked on all my VA panels in the house, fantastic help there), black was fixed by lowering displays contrast setting (this also removes a flicker issue on the LG, but none of the others)

Gsync was just by reducing the range, but when games like borderlands have all in-game cutscenes at 30FPS boosting to 60Hz was damned helpful on the eyes, even in a small 50-65 range.

70Hz no Gsync had frameskips, so that was out.

65Hz 10 bit Gsync works great, with a 63FPS cap and a 50-63 range it's working well except light flicker in load screens - but certain things like the black outlines in borderlands seems to struggle with trails at times (when the display is cold, seems part of it) hence wondering if i should ditch 10 bit and increase the blanking, but i'm unsure which values to increase - front, back, total, as high as it goes or specific values, etc.

   

As an example i tried raising that 67 by 2x (worked, lost 10 bit) and 3x (no image)

Edit:
Sigh, noticed Gsync was stuck at 63Hz instead of 65. Discovered an un-deleteable Nvidia custom resolutions that i'd used for testing were stuck and some games/titles chose those, over the higher resolution default for no reason. I hate when bugs screw with testing and make it need to all be re-done. Found them in regedit, deleted, now i get to re-test.
