GZDoom 2.0.03 released

Post by Graf Zahl » Tue Sep 16, 2014 8:37

The first non-beta release of GZDoom 2.0 is available.

2.0 is a major overhaul of the rendering system, aimed at cleaning the code base from many of the workarounds needed for non-shader-supporting hardware. It also aims at optimizing things a bit better for modern graphics hardware.

Performance improvements for GL 4.x supporting hardware can be up to 10% (NVidia) or 5%(Intel, AMD) (The high difference is due to far more efficient draw call performance by NVidia drivers, which is 20x higher than on AMD.)
The minimum requirement for this version is OpenGL 3.0, so it should run on all modern hardware, including Intel GMA, but please note that this has not been tested on Intel GMA 3000 so I cannot guarantee that this GPU chipset actually works, as its drivers may lack a few features GZDoom takes for granted. Feedback regarding this issue is appreciated.

There are only a few new features here, the main goal with this version was to create a foundation for future improvements, but the most notable is that the dynamic lighting system is now entirely based on shaders - the old multi-layer-texturing method to apply dynamic lights no longer exists. This should bring some visual improvement for hardware which couldn't support this method with GZDoom 1.x.

What are these improvements, I wonder?


Edit: Hmm, dynamic lights have become a performance killers with 2.0.3. Whenever a few of them are in my view, my framerate is just hammered down! Take Doom 2's Courtyard (map 18) with its health and armor bonuses in the main courtyard area, for instance. With GZDoom 1.x, this is of no problem, but with 2.0.3, it is.

Knowing my luck, this is probably because I lack support for GL 4.4, right?

The problem with texture based lights is that they lack dynamic range, they are always clipped when each color channel reaches 1.0 or 0.0. This prevents lighting of very bright surfaces and causes visible banding with some colors, especially orange/red.

Your problem with lights isn't lack of GL 4.4. My guess is that your driver reports support of a feature that's only poorly supported. Can you post your extension string? I have a certain suspicion. Can you try starting the engine with '-gl3' on the command line? That disables any attempt to use GL 4.x features for anything.

I feel a bit guilty for just waiting for this to come out - I haven't contributed a single benchmark, test etc. Nonetheless, I am still happy to have a new stable release of GZDoom at my hands. Good job.

Yes, using -gl3 solves it!

As for the extensions, here is what the console log reports:

Aha!

Seems the implementation of the shader storage buffer object is somewhat broken in that older AMD driver. Why am I just not surprised... :?
Ok, it seems a 2.0.04 is in order that only uses this buffer type on more modern drivers. The light stuff also works with uniform buffers, but they have quite a bit more overhead on the CPU so I'm only using them when the more modern thing is not reported.

As ever, thank you very much for your continued work on GZDoom. It is much appreciated.

Unfortunately, I've got a bit of a bug for you:

Any ideas?

(Also, I noticed that glew32.dll, which was included in with beta versions, was absent from the official release. Anhy reason for that?)

Dear Mr Graf!

Once again many thanks! 8)
It works fine on Win7 with an NVIDIA card running with OpenGL 3.3.
Questions: There's a new menu entry in the OpenGL texture settings. What's it supposed to do?
Do you expect a performance gain with OpenGL 3.3? 2.0.3 appears to give half the frame rate of 1.8.6. I'm not complaining, since the gfx card is fast enough anyway. I'm just wondering. :wink:

On all GL 3.x hardware I tested this on frame rate was approximately the same as 1.8.6. What hardware are you running?

I tried GZDoom 2.0.03 again without the glew.dll present in the directory, and it made no difference - I got the same error message as before. (version 2.0.01 worked just fine with glew.dll present, however.)

I got that std140 thing once, too, which is strange: That's perfectly valid GLSL syntax, suggesting a driver bug. Hm...
But it somehow disappeared and I never continued the investigation.

Got the same issue with the ''std140'' syntax error as Jamesff.

Using Intel HD Graphics 4000 (Core i5-3317U).
