any idea how to make xonotic look like a 90s shooter?

i'm thinking no filter on textures (3d and 2d), the gun is in the middle and very pixelated stuff going on as well. Any way to do this on xonotic?

do (in console):

gl_picmip 5-10 (depends on what you feel looks more like what you want)
cl_gunalign 2 (not sure about this one)
r_viewscale 0.5
