Debug support

[dpJudas]

Here's a pull request adding support for the debug API introduced in OpenGL 4.3: https://github.com/coelckers/gzdoom/pull/82

It contains a new class called FGLDebug which logs OpenGL debug messages to the console, if enabled with gl_debug_level 1 to 4. It is best used along with the existing gl_debug cvar that makes gzdoom use the OpenGL debug context. When enabled, it writes out debug messages of the following form:

[api] high severity, error: GL_INVALID_ENUM error generated. Cannot enable <cap> in the current profile.
[api] low severity: Framebuffer detailed info: The driver allocated storage for renderbuffer SceneDepthStencil.
[api] low severity: Texture state usage warning: Texture 0 is base level inconsistent. Check texture size.

I've also introduced a gl_debug_breakpoint cvar that will trigger the debugger when encountering one of the messages. This allows an easy way to get the call stack of what code triggered the message. This only works if the message is generated after FGLDebug is created though.

Finally, there's one or two commits in there that fixes some OpenGL errors (one for sample count, one for glBindTexture in FGLRenderBuffers.Setup).

[Graf Zahl]

I saw some changes to gl_multisample in there. What was wrong with it?

[dpJudas]

Turns out that the sample count passed to OpenGL needs to be the actual number (i.e. 16 for 16x) and not some bit shift count. Some bug during development had gotten me confused where it seemingly wouldn't create the buffer when I passed in 16. I'm not entirely sure if it was a driver issue or not because I updated my driver since.

The good news is this allows me to actually run at 16x and 32x. The bad news is that this doesn't really fix the multisample issue you mentioned on the zdoom forum.

[Graf Zahl]

You mean the slowdown? I think that's simply the card getting maxed out and stalled. The 550Ti was a medium range card from 4 years ago so at some point this would be inevitable.

[dpJudas]

The thing that annoys me so much about the slowdown is that, theoretically, from how I understand GPUs, there shouldn't be a slow down (when compared to WGL multisample). That a render buffer and a back buffer is basically the same thing. Obviously my understanding is wrong somehow, but it annoys me greatly when I don't know why.

[Graf Zahl]

Of course it's the same. The problem occurs later, when the buffer gets rendered to the backbuffer. This is additional work, after all.

JUst FYI, on the Geforce 8600 I had a comparable unexplainable slowdown on one particular map with an excessive amount of crossbeam textures plus tons of skybox portals. It worked decently on everything else, just on my system it utterly tanked.

[dpJudas]

Yes, but that additional work should be a constant time regardless of scene complexity. My understanding of your numbers were that they only got this bad when tested with the GTA map and not something really simple like Doom 2 map01.

[Graf Zahl]

I think the problem is that without an offscreen buffer to wait for that added processing time is hidden somewhere else in the process. Maybe some internal triple buffering or stuff like that. Of course this can't be done if the final presentation step has to wait for the scene to get fully rendered.

[dpJudas]

Triple buffering could explain it, but then I would have expected you to experience some level of input lag when using gl_vid_multisample. I can try make an experimental branch where I double the amount of buffers to see if it does anything on your system.

[dpJudas]

Here's a test branch where it double buffers the render buffers: https://github.com/dpjudas/zdoom/tree/d ... nderbuffer - surprised me how easy it was to get. All I needed was another instance of FGLRenderBuffers and then a swapvalues call in CopyToBackbuffer.

[ibm5155]

Since (I belive) the worst case is going with the amd gpus, coud GL_AMDX DEBUG help with something?

[dpJudas]

The PR is already using that extension. You could try run it on your system and see if it reports anything interesting in the log.

To do that, git clone the branch at https://github.com/dpjudas/zdoom/tree/debug. Then boot gzdoom, set gl_debug to 1 and gl_debug_level to 4. Restart gzdoom (to make gl_debug take effect). Then do your usual windowed/fullscreen stuff and paste the resulting log here. Change gl_debug and gl_debug_level back to 0 when you're done. Otherwise you risk running an OpenGL debug context in the future, if this PR is merged into master.

Wow, Intel. Reporting an issue but no details? That's realy, really useful... At least AMD also prints the incorrect value.

That's classic Intel. Only the best for OpenGL!
