Gzdoom gives me a black screen in full screen mode (sorta)

[angelus04]

how do I run Gzdoom with the command line parameter -glversion

[angelus04]

Here is the log file what gl version should I change it to

[angelus04]

int FLightBuffer::BindUBO(unsigned int index) was never called.
I don't know if it's related to the latest gzdoom build or the new AMD driver that I installed, but the problem looks like fixed

BindUBO wasn't being called because the buffer type was 3529506816 (decimal not hex), I also tried to force it to go inside the BindUBO call but it only resulted in a division by zero (mBlockAlign = 0)

EDIT for the gpu info:
AMD HD8870m.
gzdoom short log:
GL_VENDOR:ATI
GL_RENDERER: AMD RADEON R9 M200X SERIES (AMD renamed that gpu :v)
GL_VERSION: 4.5.13440 CORE PROFILE CONTEXT 0 (CORE PROFILE)
GL_SHADING_LANGUAGE_VERSION: 4.50

GL_VENDOR: Intel
GL_RENDERER: Intel(R) HD Graphics
GL_VERSION: 4.0.0 - Build 10.18.10.4276 (Compatibility profile)
GL_SHADING_LANGUAGE_VERSION: 4.00 - Build 10.18.10.4276

where do I find a newer driver for my gl renderer

Interesting. It doesn't even use the uniform buffer, it uses the shader storage buffer.
In that case I suggest forcing use of a uniform buffer.

For that, comment out line 217 in gl_interface.cpp:

gl.flags |= RFL_SHADER_STORAGE_BUFFER;

and test again.

should the offset be Always zero?
Here's what I took

Code: Select all

load
index = 0
mBlockAlign = 1024
offset = 0
mLastMappedIndex = 4294967295
mLastMappedIndex = 0 //after entering the if (offset != mLastMappedIndex)
return 0
=========
torch spam
index = 0
mBlockAlign = 1024
offset = 0
mLastMappedIndex = 5120
mLastMappedIndex = 0  //after entering the if (offset != mLastMappedIndex)
return 0
======== 
even when the index changed, the offset was Always zero

I did a "torch spam" in both cases, but it looks like they got the same fps, somehow, I belive the new amd beta driver fixed the dynamic light gonig off

The offset will only change if the visible buffer 'window' needs to change. And as I said, for shader storage buffers this is not needed as those can be a lot larger than uniform buffers.

But good to see that the latest driver fixes it, so it looks like this was indeed a driver bug (meaning I can close it.)

[angelus04]

Does anyone have a link to the latest driver for my GL renderer. I wonder if updating it will fix my problem

Have you tried the official site?

[angelus04]

Ok I downloaded the Intel Driver Update Utility and it gave me two updated drivers I'm going to install them and see if it fixes my problem. I installed them I still have the issue

[angelus04]

Ok this is strange I was looking for an alternate source port that does most of the things that Gzdoom does and came across Zandronum for some reason it works fine but Gzdoom does not wish someone could tell me why. It's not the wads I'm using as I encountered the problem in Gzdoom just loading the regular game. However I loaded Zandronum and no graphical issues I even loaded up the source port in OpenGL to see if I'd run into the issue it works fine in both software and Opengl. The problem is a mystery that completely baffles me.

even if the screen is black if you press enter, enter,enter on doom 2 (this results in open the menu, new game, open the map01), do you see the map? I remember a long time ago where the menu was just black for me under my intel hd 4000 but the game was rendering just fine

Unfortunately when I hit enter, enter, enter the game does start but the screen is still black no map is visible. Oh well Zandronum works fine for me as a substitute until the problem is fixed.

Which version of GZDoom are you using?

Have you tried any older version of GZDoom?
