I've recorded a video of gameplay on 1.5.5 pre (SDL3) with the same video options as previously (but with no r_skippostprocess=1 this time - maybe that's because the video stutters at times). Some shadows seem buggy (that's mostly visible when flashlight is on) and the reflections on weapons are somehow trashed. Other than that - SDL3 has massively improved game stability. I haven't been able to crash it so far.

@Koszer

skippostprocess is needed not only for the MOS version but also in Debian with Nouveau drivers (or at least at the time I tested it). Maybe a Mesa issue that inherited tinygl ? Of course it doesn't lag on a nowadays pc but the issues with missing textures look the same.

"reflections on weapons thrashed" If you're refering to the weird rendering on some surfaces it's something that the testing tinygl does.

Other things that fail: doublevision that shows a frame with a bad texture in it (before it was upside down) and also the use of the "heart of hell" in ROE that is totally wrong at the time of slowing time. Both effects are linked in the same render functions.

What was fixed in tinygl some time ago is the grabber weapon: Before, you levitated objects and the distorted images were upside down.

Thanks to Beworld for helping doing the work of merging latest github updates, putting the MOS changes and his own stuff in SDL3. Yep, I still have to update my own github with all the crap I added ....

Hi everyone,

Doom 3 isn't working properly in MorphOS 3.20 anymore, because the entire screen goes completely black during gameplay.

To confirm this, I performed a fresh clean install of MorphOS 3.19 and installed SDL2 and SDL3, and the game runs perfectly fine (PowerMac G5 with x1950 Pro)
Then I upgraded from MorphOS 3.19 to MorphOS 3.20, and now the entire screen is completely black during gameplay (changing any settings in F10 doesn’t make a difference).

Does anyone know how to fix this issue?
Thanks

Here’s some additional information:

After confirming that updating from MorphOS 3.19 to MorphOS 3.20 caused Doom 3 to stop working properly (the background was completely black), as a last-ditch effort to resolve the issue, I tried updating SDL2 to the latest version 2.32.11 and SDL3 to the latest version 3.4.10, then rebooted MorphOS, but the issue with the game persists.

The version I’m using is the latest one in morphos-storage, namely Doom3_1.5.5pre

I suspect at this point it’s a compatibility issue with the latest version of TinyGL in MorphOS 3.20; since I don’t know how to fix it, I’m asking help you guys
thanks

//add note
I just noticed that there was also a version by @beworld, but it’s no longer available for download. If anyone still has it, I might give it a try.

I can only confirm, tested on X5000/40 with X1950 and on the beginning of the game can see only some upper lights and terminal screen, everything else is black.

exactly @pampers

I was thinking of trying the previous version of @beworld in the meantime, but I see the file isn't available anymore. Does anyone have it so I can try it out?

Unfortunately, TinyGL on MorphOS 3.20 no longer supports the rendering needed for Doom3. In fact, TinyGL uses a 'texture mapping' for fog effects, which causes a small problem for Doom3... Hopefully we'll see a TinyGL fix in the next MorphOS update.

@beworld

Thank you for your reply
Too Bad, I guess I'll have to set up a dual boot (3.20 and 3.19) for now, hoping it will be fixed in the next version, 3.21.
