OpenGL vs Direct3D - most games don't use OpenGL.

A suggestion: try a totally fresh, vanilla Quake installation, with unmodified PAK0.PAK and PAK1.PAK, and nothing else.

I'm not suggesting this as a solution, it's a troubleshooting step - just trying to carve up the problem and see where the cause might be. 

I have a sneaky suspicion that you've managed to get a bad opengl32.dll into your Quake folder is what I'm saying.

This would be helpful, and if you don't mind, please post the console log again as I'd like to confirm what driver version the engine is picking up (iirc I've seen intel driver installs seem to work and then not actually end up being used.)

We did have report of corrupted textures in July with:
GL_RENDERER: Intel(R) HD Graphics 530

Unfortunately the only Intel graphics I have handy is HD4400 which runs a a different driver, and the latest drivers work fine for ne,

Introduction
Using protocol 666
Couldn't find a cdrip for track 4
=====================================================

The same thing happens with a fresh quakespasm install and a fresh copy of the paks, it launches but the demos don't load and it crashes when I try to start a new game. And it would indeed appear the 24.20.100.6229 drivers are being used. So it isn't that unless there is something wrong with the drivers themselves in which case I don't think I can do anything about that... 

Running it with -noglsl does work though, so I guess all this bickering is for nothing :D But when I do -noglsl the mouse is stuck on top of the window which causes the game to lose focus and minimize itself whenever I click, this behavior was the exact same on 0.93 as it is on 0.93.1 and I actually pointed it out yesterday as well. But, why would I need to put -noglsl when the card has GLSL and other engines accept it? Ugh. 

It does sound like a driver bug to me.
If anyone else has an Intel laptop that is compatible with this latest driver, it would be interesting to hear if you can reproduce the crash:
https://downloadcenter.intel.com/download/27894/Intel-Graphics-Driver-for-Windows-10?product=80939
(there's a long list of supported model numbers there, includes HD Graphics 500 and 600)

But when I do -noglsl the mouse is stuck on top of the window which causes the game to lose focus and minimize itself whenever I click, this behavior was the exact same on 0.93 as it is on 0.93.1 and I actually pointed it out yesterday as well.
I have no idea how switching the rendering code path could trigger this. :(

btw another engine worth trying is vkQuake:
https://github.com/Novum/vkQuake/releases 

The mouse going over the window instead pf being attached to it only happens in fullscreen, I'm wondering if it's part of the same driver issue. And it's also only a quakespasm problem as far as I can tell... 

Intel UHD 620, driver version 24.20.100.6229 (latest), Quakespasm 0.93.1, clean configs, no command-line args, Windows 10 1803 fully-patched.

Tested various windowed modes, as well as fullscreen at both 1920x1080 and 640x480; runs without crashing.

NOTE: the mouse pointer thing does not happen at 1920x1080 but does happen at 640x480. This is caused by Windows, not Quakespasm - specifically the "Optimal resolution notification" warning. To stop it, you need to set your Windows resolution to something lower than native, then click on the warning when you receive it, where you will get an option to disable it. This option is probably also buried somewhere in the Settings app.

Alternatively play at your native resolution - I seem to recall that Quakespasm has a video-scaling feature to emulate lower resolutions but I can't remember the cvars to use.

For completeness, here's the stdout:

Shutting down SDL sound 

That was me, by the way. 

I see, well I wanted to play on a lower resolution than native for performance reasons (never really tried playing at native res but I just wanted to be safe) though I suspect the CPU would be more of a hindrance to fps than the GPU, it's only a dual core @ 2.6ghz :( Also I'll disable the "optimal resolution" bs ASAP, I knew that it popped up every time since I would see it in the notifications after I exited but I didn't know it was causing the focus pro len :o. 

Yeah, it seems to be trying to steal the focus and having a good old fight with Quakespasm over it.

I'm sure that there's probably a more general solution to this.

Regarding performance, Quakespasm should be considerably less CPU-limited than other Quake engines (and certainly less so than the original FitzQuake base, which was very CPU-limited and contained a high number of pipeline stalls per frame), but for Quake content you should get decent performance at almost any resolution. 

Good to have confirmation that the latest intel driver doesn't crash for you.
Still at a loss as to why the QS OpenGL 2.0 renderer isn't working for therektafire. Could be we're doing something unusual that triggers a driver bug with his specific hardware (UHD 600 vs your UHD 620).

also thanks for the reminder about the "optimal resolution" thing, now that you mention it, I remember seeing that as well. 

could it be possible that another program like TB messed with something? I know TB's min. OpenGL requirement is 2.1... 

Well TB runs surprisingly smoothly on it all things considered, at least with the smaller maps I've given it so far. There aren't any errors with it or Wally or any other quake related app tat I've tried so far. Also the hd 600 supports opengl 4.5 so I don't see what the requirement of opengl 2.1 would have to do with anything unless you are implying that it changed some driver setting? Does/can it do that? If so that's kind of problematic since it shouldn't exactly be doing that to begin with... 

<Q>Still at a loss as to why the QS OpenGL 2.0 renderer isn't working for therektafire. 

 

Antialiasing is not working for me.I try FSAA command and its not working.What am i doing wrong? 

Little confused about something: does Quakespasm (as of 0.93.1) now have IPv6 support or not? I saw an earlier post (#3469) here of a condump that had it enabled. 

No. That was probably a condump from Quakespasm-Spiked which does:
http://triptohell.info/moodles/qss/ 

Increase MAX_GLTEXTURES from 4096 to 8192. Or have a command line similar to -heapsize, like maybe -texsize to force the larger texture bank alloc.

It seems I found a new hard limit and can't add anything with a new texture, sprite, model, or otherwise. 

I noticed the same bug in QuakeSpasm: https://github.com/yquake2/yquake2/commit/587382644c78e591e199d14efbb9220f8267152e 

What can I do to make Bal's beautiful Xmas map not look like a slideshow on my laptop. Thoughts? 

Try disabling the extra particles added by AD. 

How to?
