DirectX9 vs DirectX11 - Automatic Scaling

[DamienD]

Not sure where to post this; it's not really a WinUAE issue but.

...and sorry for the large images.

On my laptop and with WinUAE I have to use DirectX9. One main reason is the aspect ratio is correct:



While playing around with configs for Heart of Darkness - Amiga port possible?, the CPU going above 100% and then the sound issues I experience go away if I use DirectX11.

The problem for me with DirectX11 is that it automatically scales to the full resolution of my laptop:



I can't go anything about this with my graphics card settings...

Anyone know if it's possible to turn off "automatic scaling" with DirectX11 via say editing some file or registry hack?

I've tried Google'ing and am currently reading through this long-winded thread: https://social.msdn.microsoft.com/Fo...orum=wpdevelop

What happens if you try windowed or full window ?

Have you checked your graphics card driver settings? For preservering the aspect ratio while scaling with non native PC resolutions.

"Windowed" or "Full-window" are fine, but I always run my emulation in "Fullscreen"; well, at least when gaming.

Of course I have Retro

...and all is working fine with DirectX9; as you can see from my screenshots.

It's just DirectX11 that has the issue

What is the resolution you selected for fullscreen ?
Is it the same for DX9 and DX11 ?

The thing is, DamienD has not even told us WHAT his system specs even ARE, so how can we help him if he neglects to tell us that info?

I myself have no problems with my Intel Core i3-8100 with UHD 630 APU, I can run WinUAE fullscreen, with the driver's aspect ratio settings applied, on either DX9 or DX11.

It is normal and there is nothing WinUAE can do. D3D9 and D3D11 have some behavior differences which can be (usually) overridden by GPU control panel.

My Intel UHD Graphics Control Panel has a scaling option for aspect ratio right there (I have it ticked) and it appears to behave the same for both D3D9 and D3D11.

What graphics do you have in your laptop, DamienD?

Try starting from my cfg settings in signature. I don't have that issue and Native PAL/NTSC is correctly scaled for me in DX11.

Yes, the same resolution and exact same config; the DirectX change obviously.

Unfortunately there's nothing for me to change for scaling in my Nvidia control panel for the Nvidia GT 540M card.

On the Intel HD Graphics 3000 card though there is; and it's set to not scale.

As mentioned, D3D9 doesn't automatically scale, it's only D3D11 unfortunately.

My old "Acer Aspire 5951G / i5-2410M" laptop specs are here.

That works, but you are playing around with scaling in the config under "Filter" i.e:

Aspect Ratio Correction = Automatic, Keep aspect ratio and VGA
Scaling = Fullscreen (Max)

Guess it's better than nothing though; thanks
