Xenia: Xenia Experimental 2x Resolution Scale bugs

This works on x1 as default. Which key for initial 2x? Now any keys for command line not works for me.
I see "resolution_scale_2x_ = false" in source code and label "direct3d 12 - rov 2x" (for title of xenia window)
@niko1point0 i see your title as "direct3d 12 - rov" and think what there still x1 scale
Tell me how to use the keys now to run? Thx

Append --d3d12_resolution_scale=2 to the executable path in your shortcut to the latest version of Xenia. Your GPU must support tiled resources and rasterizer-ordered views.

Scale 2x does not work on RADEON R9 390

[Prism019]

@altiereslima that's because the Radeon R9 390 does not support rasterized-order views, or ROV.

Ok

Eternal sonata: A kind of flashing of the half bottom screen all the time, else is perfect. This doesn´t happen in 1x.

Bayonetta: Entire screen black-flashing sometimes.

Resident evil 6: When ingame, only the HUD is rendered correctly, all is a blackscreen with exploding vertices. The game in 1x runs near perfect. (Except for a few minor bugs like characters with no face in cutscenes, and no laser-dot can be seen in the weapons)

All games runs incredibily slow with 2x: I can run cemu in 4k and rpcs3 too, I assume this is because this PR is only experimental and not perfectly implemented yet.

Oh, damn it! I really wanted this feature. Unfortunately I bought an RX card last week and my card is not compatible. Only Vega cards are compatible on the AMD side.

Will we be able to increase the resolution of games in the future with older graphics cards? Or is it only possible with cards that support Directx 12_1?

@xbox360pad The main reason for this being ROV-only is performance, the legacy path is already slow because of lots of copying, and it also uses SSAA instead of MSAA, so applying both would mean 8x (in Call of Duty, GTA IV and Red Dead Redemption, for example) or 16x (in Halo 3 main menu) the resolution. It's not difficult to make this feature available on the legacy path, would just require making some changes to EDRAM shaders and the host render target code. Later I will probably add a command line switch that disables SSAA since it's not needed very much at higher resolutions.

Sonic the Hedgehog 2006 has weird shadow/light bugs that cause flickers with ROV 2x enabled.
