Definitely making really great progress. I think to cap it all off you should add the ability for user to adjust the bicubic parameters of B and C. Catmull-rom has...

Another tidbit, this one is specifically on sigmoidization: "You may decrease halos and increase perceptual sharpness by increasing the sigmoidal contrast (up to 11.5, say). Higher contrasts are especially recommended...

I've tested your downscaling, it works pretty well. couple example images taken on my 1920x1440p display downscaling from 3840x2880 with integer overscale on in retroarch. original(outside gamescope, no scaling): ![native...

Sharp-Bilinear is for upscaling. Works by going to the nearest integer then finishing up with bilinear interpolation. It won't help here as the default for gamescope is already to do...

I think all that's needed here is an optional smoothing filter(0-100 scale with 100 being smoothest/blurriest) like the one included with Nvidia's DSR and DLDSR on windows.

Doesn't happen to me. Make sure your monitor is set to 640x480 from display settings before running that.

Want to issue a retraction of the following: "which has almost identical effects to using sharp-bilinear(fractionally scaled output without pixel wobble, scaling artifacts in general, perfectly sharp)." It still has...

I've got a comment of value to add: the best downscale quality is achieved with B-Spline, which is a mitchell-netravali filter(param B1 C0). It only adds blur, no aliasing/blocking/ringing. The...

For me Gamescope often works on fullscreen, but sometimes freezes(have to kill the gamescope-wl process). I have a 3080. Xrandr already has better SSAA/downscaling than gamescope upstream by default, probably...

I propose changing the flag from -D to -B(for bicubic, since the -B flag is not used, bilinear is the default and doesn't use a flag) to more accurately reflect...
