thanks for the replies. i'm clueless about the technical details, but while playing
with the Winuae D3D CRT shader, i came to the conclusion, the WinVice CRT emulation looks much more realistic

#1) vice source files at sf.net
#2) vice-2.4.33\src\crtc: crtc.c - A line-based CRTC emulation (under construction).
--> at least i think this are the relevant parts

dosbox has a decent shader called crt-geom-curved in .fx format but for some reason it is not working on WinUAE

same here, it freezes the emulation, but no crash.
changing the shader, makes the emulation responsive again.

which pixel/vertex shader version does winuae expect?
gpu-z says here 400 unified shader/ dx11 support.
is there another tool that lists exact version of the shader?

I have that same feel about the PAL filter on WinUAE too. My main complaint was about how inaccurate copper rainbows were rendered when it was enabled. I have talked with Toni many times in the past about this subject, and him said that the filter precalculates the colors it will use with 16-bit color precision.

I don't know what Toni will say, but I think the PAL filter is worse on WinUAE because the Amiga display needs 32 bit color for it be rendered accurately, while the C64 needs only a fixed 4-bit color palette.

About the Direct3D filter not working, try this link:

Yes, it is same answer: Those software filters for low resolutions and low color depths are useless for Amiga emulation. With higher resolution support and deeper colors they will become painfully slow.

i pulled off a decent mask by copying a BVM screenshot pixel, then making a simple png in photoshop
If someone doesn't cares for curvature i think this effect is more than enough.

i like the way the scanlines were done, not bad.

so the vice crt emulation is of no use for winuae/amiga emulation - as mentioned by Leandro above?

4x with help from 2 shaders of Dosbox, bilinear and dotnbloom, then a mask is applied:



and (too big to post here)
