High resolutions PC screen with WinUAE+P96

[hexaae]

I have a problem... A new gaming laptop PC with 2560x1600 16:10 screen (ASUS SCAR 18 G834JY) and I'm trying hard to set a decent resolution on this bigger screen (I came from 1920x1080 which was still very good with WinUAE + P96 at Workbench) not too smudgy and blurry.

I tried with Host > Display = Native (2560x1600), WB P96 screen set to 1280x800, and Filter (RTG) = D3DScale2x but it's horribly blocky (more like "D3DPixelize2x" than a pixel doubler as I expected).. and other combinantions but can't find decent settings to have pixel perfect crispy 1280x800 WB screen pixel-doubled to 2560x1600 (to use native screen res without blurry effect).
Suggestions? How can I do?

I haven't tried it myself, but how is the result if you select 'Null' as the filter and then 2x?

changing that value 2x or more has not effect (buggy?)

Tick Integer scale in RTG panel and set full-window mode. It should be perfect fit with 1:2 integer scaling.

On my 2560x1440 monitor I use 1280x720 resolution with auto integer scaling. With no bilinear filtering it's perfect 2x pixel doubled.

That's too sharp for my taste. The bilinear filtering in WinUAE is also too blurry for me. (I think somebody said it's because filtering is applied before scaling?)

Instead I run ReShade on top with a third party shader called 2D Scaler. That's absolutely perfect.

Yeah don't like it either... definitely too blurry. Would be great if we had more options or a "sharpen" option for the bilinear filter... I solved similar (too) blurred bilinear in MAME with x3 pre-scale option... not sure if WinUAE could adopt similar tricks to adjust sharpening.

Where is this? Uh sorry, it's a relatively "new" option.
I solved disabling Point/Bilinear which was 1. 0 = disable is ok and pixel perfect and crispy. Have to get used to the larger icons and GUI of WB, coming from 1920x1080 and now in 1280x800 double-pixel

1680x1050 (on a 2560x1600 18" screen) would be perfect to keep almost the same old proportions I was used in 1920x1080, but looks blurry with Point/Bilinear ON, or blocky/badly-resized with it OFF...
