Valid values for DOSBox 0.74-3 are : surface, overlay, opengl, openglnb, ddraw.
Valid values for DOSBox Staging are : surface, texture, texturenb, texturepp, opengl, openglnb, openglpp.
Valid values for DOSBox-X are : default, surface, overlay, ttf, opengl, openglnb, openglhq, openglpp, ddraw, direct3d
"nb" suffix is no-bilinear filtering, "pp" is pixel-perfect / integer scaling. Staging is missing the "ddraw" option that ordinary DOSBox has, whilst DOSBox-X has more render options.
