Yes, SVG does upscale very well but its downscaling is more aliased than textures, this is a DCS limitation. For low res screens, we added the possibility to make lines thicker:
Copy
Program Files\Eagle Dynamics\DCS World\Mods\aircraft\M-2000C\Cockpit\settings.lua
Into
Saved Games\DCS\Config\M-2000C\settings.lua
Then, keep only the vth_thickness and vth_fuzziness lines, and adjust values (increase). This will improve aliasing on low resolutions. It's a temporary solution, we might add nice sliders in special options in the future.
