With the newest WinUAE 2.0.2 beta 5 we can now combine scanlines and scalers. I found a combination which looks really nice: 25% scanlines and Super2xSaI.
Doesn't look as pixelated as 25% scanlines without scaling algorithm.
And doesn't look as blurry as 25% scanlines with bilinear filter.
Which one of the following looks best?
Super2xSaI with 25% scanlines:
Again for comparison 25% scanlines without filter:
And 25% scanlines with bilinear filter:
P.S. These'll be the last pics for a while...
