I've tried every setting from 1-8, with Bilinear on and off, and with Effect Default and Effect None. I took screenshots and compared in gimp. It works as expected with D3D and OpenGL. The difference between 1 and 3 with those video modes is so apparent I didn't even need to open gimp.
Is this working as intended? Am I suppose to create a .json to get the desired prescale before the bilinear filtering is applied?
Also, -nothrottle doesn't work with -video d3d or -video bgfx -bgfx_backend d3d11 or d3d12. It'll only run it at 100%. -video opengl and -bgfx_backed opengl and vulkan have no problem running over 100%.
