RTG Centered Integer Scaling

[PoulpSquad]

Good morning,

Is it possible to set WinUAE RTG mode as centered integer scaling?

My monitor is ultra-wide and capable of displaying 3440x1440 but nothing is readable at that resolution.

I've set a custom resolution in NVIDIA control panel (1280x960x32 @ 60Hz) and things are better, but WinUAE stretches the screen vertically to 1440.

How can I force WinUAE to keep the RTG output centered and integer-scaled?


Thank you for your time reading this!

RTG manual integer scaling multipliers and automatic integer scaling are already implemented in current development version.

Forever grateful for your stellar work on WinUAE.

Thank you very much!

I understand that this development version is not yet public, right?

[Toni Wilen]

Latest alpha version is here: https://www.winuae.net/files/b/winuae.7z
Sometimes it might crash immediately, nothing guaranteed.

[PoulpSquad]

Thank you for the alpha binary.

So far I didn't notice any difference in behavior compared to the non-integer version.

I need to make a new ad-hoc configuration file tomorrow.

RTG panel -> Integer scaling (uses window size as defined in Display panel), don't tick other scaling check boxes. Make sure Misc panel gfx mode is Direct3D9 or 11.

I've made a new configuration file and I am using Amiga Forever 9 directories that came straight from the ISO, so I get everything I need to check stuff.

I've set a screen size of 800x600 in Workbench, which would fit x2 vertically on my monitor (1440 vertical pixels) and leave black bars on top and bottom.

What I'm seeing is that RTG is stretched vertically to fit the monitor.

I'll attach the configuration (I based it on the A1200 config from Quickstart and changed some values to make it compatible with RTG).

[Toni Wilen]

Fixed. Integer scaling only worked in windowed mode.

btw, unless you need to change refresh rate or use vsync (which is rarely needed in RTG modes), I recommend using full-window instead of exclusive full screen. If you want to use exclusive fullscreen, make sure Display panel fullscreen resolution is set correctly. In integer scaling mode native resolution is always whatever Display panel is set, even when using RTG modes.

[PoulpSquad]

Thank you Toni.

I'll make sure to set it as full-window.

Edit:

I just checked the updated binary and that is exactly what I had in mind!

My test setting is now full-window using software DirectX 11.

800x600 is nearly perfect, screen is doubled on X and Y axis with letterboxing and correct aspect ratio, even with aspect correction turned off.

There is a bit of an artifact on the right edge of the screen, I'll attach a screenshot.

Can't wait for the next release of WinUAE, thanks a lot mister!

Does it only appear in integer scaling mode? (I can't duplicate it)

[PoulpSquad]

No, it does the same with aspect correction=automatic and Filter/RTG/No Scaling also.

The interesting thing is that it doesn't happen in 16 nor 32 bit modes.

I copied over my usual configuration file with the matched hdf, which has P96 updated to version 3.3.1. Same behavior, 16/32 bit modes are ok, 8 bit modes have the artefact, with or without integer scaling.

Speaking of integer scaling, I noticed something weird when I ran ShapeShifter.

It is set to use an RTG screen of 640x480x8, and there is a scaling artifact in the middle of the screen.

I think that is weird, because my monitor does 3440x1440, so ShapeShifter screen should be stretched exactly 3 times vertically and horizontally, leaving 2 black bars 760 pixels wide on both sides. The artifact is 5 monitor pixels wide instead of 3 like all the others, and happens seemingly exactly in the middle.

[Toni Wilen]

Both bugs should be fixed now.

[PoulpSquad]

Thank you for looking into this.

ShapeShifter RTG screen and upper right corner issues are fixed!

I applied a similar pattern to the Workbench as the MacOS one, as it makes scaling issues obvious.

Screenshots attached. Resolution=960x720x32 and 800x600, both with Aspect Correction=Auto.

Disabling aspect correction now stretches the screen outside monitor bounds

I just noticed that the screenshot with aspect correction disabled is 2331x976

EDIT:

640x480 works fine. I guess you have fixed 640x480 first and will apply the fix to other modes later?
