WZ crashes on multiple devices

[Vincent]

Actually debug Tools don't help with crash, they often use classic GL introspection functions so that they will provide the same reports as arb debug output. Tools from IHV only give access to the performance counters of their hardware while frame capture is vendor agnostic as far as I know.

On the other hand they're really useful to debug visual glitches as they record framebuffer content after every draw call which allows to detect which call is not correctly working and see all the state parameters (blend, depth text, constants...).

Is e114b97c…9c261297 a step in the right direction?

[Cyp]

friend can not play with this game version unless compile by vs2013 then he have no crashes.
the problem is broken compiler.

Can confirm it crashes on Intel igpu. Unfortunatly Intel OpenGL drivers doesn't support fixed functions very well (and mixing fixed function and shaders is even worse) ; however they correctly support core context, they're even able to run the latest Doom game which relies on GL 4.3.

Was that using the standard cross-compiled .exe, or a version you compiled with MSVC?

[Vincent]

using the cross compiled exe

[Vincent]

I tested with msvc 2K15 build, it still crashes (in piedraw.cpp:555)

[Per]

Seems it crashes in the glDrawElements() call inside pie_Draw3DShape2() function.

Can you try the attached patch, and post the last few debug log calls that are output before it crashes?

The glc errors are probably not related to the crashes btw I get them on another computer which run wz fine.

[Vincent]

I narrowed down what cause the errors, in piedraw.cpp at line 211 :

Code: Select all

		glEnable(GL_ALPHA_TEST);
		glAlphaFunc(GL_GREATER, 0.001f);

Commenting the functions makes wz 2100 work (at least the alpha campaign first mission).

[Vincent]

Wz2100 works with latest commit (with MSVC build, didn't test with cross compiled one)

[nooneisback]

Can someone please explain me why this thing didn't work for me 4 weeks ago (Crashed after saying "Power resource"), then when I come back, everything works perfectly fine. No upgrading or anything.

[Cyp]

Don't know. Windows autoupdate? The phase of the moon?

[nooneisback]

Didn't update since I came back, it just started randomly working...

[William]

I got that error Too!

error   |07:27:08: [khr_callback:140] GL::API(Performance:Medium) : API_ID_RECOMPILE_FRAGMENT_SHADER performance warning has been generated. Fragment shader recompiled due to state change.

I believe this is a problem with the cpu?
Too bad i aint getting anymore cpu upgrades
