Today's build starts on my on-board Intel in OpenGL mode!

Ok. Good to know. I'll prepare new tests this evening then.

Oh I can actually do that myself. Is it a separate branch or...?
Update: Hmm, this doesn't look good.
Anything that has transparency draws with flickery transparent speckles. Sometimes covering a diagonal line, and sometimes on some sort of pattern near areas where it's clipping against a wall/floor. The speckles don't move if the camera is still, though.
This is a X3100. It only covers 2.1 on Linux and 2.0 on Windows. Here's the OpenGL info:

OpenGL 2 support is still being worked on. The important thing is that it starts up and shows something that's not entirely broken.

I don't have this issue on Intel GMA 4500MHD on Windows. It has very old driver and it's OpenGL 2.0 only.
Could you please try on default settings? Or perhaps, post your config.

Default settings make no difference. This is a fresh install anyway so I didn't change much beyond the controls and disabling texture interpolation.
This specific issue only seems to happen in GZDoom. Another thing I noticed were dramatic performance drops in some areas, such as the chainsaw spot in MAP01, or the room right before the exit.
Bad performance may just be due to the fact this GPU is bad at anything that isn't fixed function, as I said before.

Every option does matter. If under texture interpolation you meant filtering, i.e. gl_texture_filter CVAR, take a look at these screenshots:
This is Texture Filter mode set to None in the corresponding menu. It's on OpenGL 2.1 by the way, so my question makes sense.
Sadly I still can't figure out what's going on. Graf just fixed it.

One thing I did notice, though, is that if I enable anisotropic filtering, texture filtering is forced to linear.

I just encountered new texture related issue on OpenGL 2.1 hardware: transparency on some textures are missing, it's just black color instead of transparent pixels. Doom II MAP26 is a good example, right from the start.
Tested on default settings, no high quality texture resizing, etc.
It seems to work correctly on OpenGL 3.1 hardware by the way.

I've noticed that for a while actually. I like the anisotropic filtering for making far away stuff look nicer, but like you said it forces linear filtering and sprites no longer have pixel sharpness.

I've noticed an interesting issue while trying out some map packs. In ZDCMP2, right after the spawn room, everything goes nuts and a lot of walls and floors stop being rendered.
Maybe it's just the high polycount.

Try:
Code: Select all
export MESA_GL_VERSION_OVERRIDE=2.1 MESA_GLSL_VERSION_OVERRIDE=120 LIBGL_ALWAYS_SOFTWARE=1
does the issue still appear?

The glitches - no. That looks like a driver bug.
The 12 fps - definitely.
Can you even play on that thing?

Graf Zahl, maybe get a Raspberry Pi for testing, it has OpenGL ES 2.0
.

GZDoom doesn't work with OpenGL ES.
