GZDoom 4.7.1 crashes on OpenGL ES (PowerVR SGX545)

[Frost-Core]

Hello! i booted up GZDoom with OpenGL ES (vanilla) and the game crashes after launch, here is my crash report :

The newest version is 4.8.0; try again with that version.

Unfortunatley, there is no 32bit version, so i used the git build and OH MY GO- :

this looks...... like nothing i can imagine it to be

32 bit support was retired for good after 4.7.1, there's no more guarantees that the source may compile.

I mean yeah, maintaining two builds can be really hard, however lets focus on the real issue :
Small screen size that makes the game unplayable, how can i fix it?

I have no idea. Your hardware is rather exotic which will make tracking this down hard.

i had OpenGL 3.0 with this DLL that does software rendering of OpenGL/ES, and that happened, without it the game does the same crash :

32-bit, with a graphics unit that requires an emulator to even run the game? (It is comparable to the GeForce 7000 series, -ish, which is already well over a decade and a half old - it's almost as old as this forum, even)

This goes well beyond the range of what we can officially support. I'm surprised the thing even runs at all.

There isn't anything we can do here, unfortunately. If you cannot finagle your drivers to work with the GLES rendering engine properly, without wrappers or alternate renderers, there's literally nothing we can do, sorry.

You might have more luck running it with Linux at least, though.

I really just wanted to use GZDoom because LZDoom is not compatible with mods that work on GZDoom 4.8.0/4.7.1

You can try softpoly (vid_preferbackend 2) but that will require setting a very low scale, it won't run well at any resolution above 960x600, depending on the CPU if we're assuming one that is around 15 years old.

It was also used on the Intel GMA 500/600 series of chips.

Which in recurrence are the modern equivalent of an S3 Virge in terms of rendering support. It stinks.

But the GPU should support the GLES 2.0 backend just fine - So that would be one facet to look into.

Unfortunately, they were having trouble with that, too:

Well it happened because of the DLL that is Mesa3D (a software renderer for gl) if i remove it the game crashes the same crash on 4.7.1
About softpoly i had terrible performance with it, really wish LZDoom could be more up to date with GZDoom's versions so most mods work

Then ill go with Intel GMA being a broken hodgepodge that can't even get its GLES on desktop support right. Out of everything Intel released in the IGP space, the PowerVR SGX ones rank among the lowest.

It takes hacked drivers to get stuff like UT99 going somewhat decently. A typical case of a low power GPU with all modern features, but barely enough juice to actually make use of 3D rendering - let alone the modern features.

So you aren't even using GLES, but OpenGL softrendering through Mesa. No wonder it bunks.

LZDoom is semi-inactive.
