Resolutions more than 640x480 breaks menu and videos

[atauenis]

With default d2gi.ini the intro video and menu looks as a checkerboard garbage if it's first run, and as just artefact garbage if game were launched before:

The app is still responsible to keyboard, it is possible to skip the intro video, and start new game, then it appears good, and game starts correctly in native resolution. But videos on events ("unrecoverable", "caught by police", etc) are broken (displaying as a garbage). Also if exit to menu, garbage appear instead of it. The left-pane mini-menu, the choice screen on "unrecoverable" (after throw the car into river :) ) state and the pager are okay.

Log file does not containing anything bad:

Tried to change options in d2gi.ini.

Found that fullscreen mode makes black screen instead of garbage. Windowed mode is similar to borderless (except that the window border is fine). But, if set D2GI resolution to 640x480-799x599 pixels, everything starts working as need (except fullscreen). Intro video, menu, game, event videos. Setting resolution to 800x600 breaks intro video, but menu and even in-game event videos are good. And setting even to 801x601 breaks all videos and menu (no difference to 1400x1050). Fullscreen mode does not work in any resolution. However, setting 0/0 or real resolution and borderless is enough for me.

Other INI file options does not change the bug.

Interesting, thank you for deep testing and detailed report.
Both video stream and main menu are implemented using StretchRect method to upscale content, and seems that it can be restricted (according to docs) and even bugged (found such cases on the internet) in some device drivers. So I guess that your driver just can't upscale in some cases and frame renders with uninitialized data, which can be allocated over some memory chunks that were used by GPU in previous successfull operations - that's why you can see some broken graphics from previous game launches. This method is also used for wet windscreen rendering (and as far as I remember - to grab background for left-pane menu and pause screens), but here scaling doesn't happen, and looks like that your driver works correctly in such cases (I don't see related errors in your report at least).
It can be reimplemented using shaders - the same way as for in-game UI, and I'm almost sure that it will work fine, as UI renders well for you.
I crafted special build with this idea implemented, please check how it will work for you (note that it's test build with draft code, so it may be unstable). I also added little debug output, so show your logs after that please

Good shout on the stretching capabilities part - it can be verified further with the device caps, so this theory could be tested.

Yes, I also added caps dumping into that build from above, so maybe we'll see some interesting from logs. But now I think that it should be reimplemented via blitter anyway, as it seems to be more "stable" solution. I even don't see performance impact using this approach (quickly checked FPS on Intel HD Graphics 4000 and RTX 2070)

[CookiePLMonster]

I agree. Using a shader also opens up a brand new opportunity - if I remember correctly from my refactors, menus are drawn using palettized textures, so they could be blitted using a pixel shader that assigns colors from the palette passed as a 256x1 texture, instead of expanding it on the CPU every frame!

It would only require the D2GIPalette to become a 256x1 R8G8B8X8 (or A8, depending if you need alpha) texture in the managed pool.

The special build is working nice. This is the log after a short play:

Now menu and videos are working, but in-game videos (except intro video) are displaying at center of screen, not stretched, and with a bit of garbage on borders.

The intro video is displaying correctly, and menu is full-screen as designed.

[CookiePLMonster]

in-game videos (except intro video) are displaying at center of screen

This works as intended then, only this leftover garbage is an issue.

[REDPOWAR]

menus are drawn using palettized textures, so they could be blitted using a pixel shader that assigns colors from the palette passed as a 256x1 texture

Good idea, I'll think about it, thanks. I have feeling that I was thinking about that in 2019 already, but discarded it due to upscaling problems (linear filtering won't work for palette). However, looks like there is a way to use additional intermediate texture of same size: expand 8-bit paletted surface into 16-bit one, then upscale 16-bit surface to final render target

The special build is working nice. This is the log after a short play:

Great! The log shows that both upscaling StretchRect calls were failed with D3DERR_INVALIDCALL (I added special logic: first frame uses StretchRect, then all the rest use shaders, so only first frame fails). But more interesting is what I found in device caps. I loaded your device caps into my debugger:

As you can see, neither POINT nor LINEAR filters are supported for magnifying operations, so looks like I was right that upscaling just not implemented for StretchRect in your device driver. Anyway, the problem is resolved by shaders, I'll include it in next release.

but in-game videos (except intro video) are displaying at center of screen, not stretched, and with a bit of garbage on borders.

Yes, this is different, ancient bug from first D2GI version: background filling simply not implemented for non-fullscreen movies. I have fix ideas, but I need time to test and select most performant one

Looks like I found good solution. @atauenis new build should work well for you in that case
