Built-in shaders failed

[diabolik]

Thanks for your response, but I hope you are wrong
Let's wait a technical advice from developers.
Bye

Hmmm, there is something strange, there is already explicit code in 0.41 release to not load the SSAO shader if the GL_ARB_texture_gather extension is not supported.

Code: Select all

	if (r_ssao->integer > 0)
	{
		if (GLEW_ARB_texture_gather)
			gl_shaderManager.load(gl_ssaoShader);
		else
			Log::Warn("SSAO not used because GL_ARB_texture_gather is not available.");
	}

I don't know what is happening…

[illwieckz]

So, I've done some tests on a Linux computer I know to not have the ARB_texture_gather too, when I try to launch Unvanquished, I get:

So, the SSAO shader was automagically disabled on my old computer.

diabolik, can you double check you are running Unvanquished 0.41.0, if yes, it can means there was a problem in the Windows build.

[illwieckz]

Oh, your log said you are running the 0.41.0 binary along the 0.41.0 package…

I'm sorry there is something very strange. I've checked if the code that disable the ssao shader is in both win32 and win64 0.41.0 builds an yes, the 0.41.0 builds for windows contains a special code to not try to compile the ssao shader if the graphic card does not support it.

This is very strange because you can only have the ssao shader compilation if your graphic card support it, so you can only have a failure in ssao shader compilation if your graphic card knows it. There is something wrong somewhere, like if the driver answers that your graphic card can do it and can't do it at the same time.

I've tried to run unvanquished 0.41.0 on a graphic card that does not support the extension needed by ssao (like your graphic card), and unvanquished just ignore it because it recognize the extension is missing so it does not try nothing, and unvanquished launchs well.

Hello illwieckz

I really appreciate all the work you've done to help me

Can I ask you a last service man ? => PM me when 0.42 will be out and I'll make again the installation.

On the other side, I see my HD4850 is high-temperature when 3D : 85°C !!! So if I don't want this old card to burn/destroy my new computer (motherboard Maximus VII ranger), I must buy another one.

Thanks again, and good luck for Unvanquished project, I will bring you wolfenstein players for sure !

Offtopic it's very fun I say my card is "old", story: a friend of mine gave it to me some years ago, but I couldn't plug it on my previous computer (Pentium4 - 2,5GB - nVidia7600GT AGP 8x) so the card was in my bedroom without using until last month I bought new PC, and I've always considered it as the "new" card

Yes I can, next date is Sunday, 2015-08-02, 00:00 UTC (in 1 weeks, 6 days). I can remind you If you want, but it will be better to find what is happened in your computer to be sure it will not reproduce in 0.42.0…

I know what it is, I was still using a Pentium3 6 years ago, and the integrated GPU card alongside the CPU was only able to render full screen opengl (1024x768) in 16 bit colors, even tremulous was playable on it only with some magic, so any PCIe GPU sounds “new” to me.

The integrated GPU was only able to allocate 8Mb of shared video memory, my current GPU has 3Gb of dedicated memory, I can't know where “new” begins between these two values. Everything sounds “new” to me if it's not AGP.

Thanks again, and good luck for Unvanquished project, I will bring you wolfenstein players for sure !

Nice, I hope you will be able to play Unvanquished soon. Do you play ET:Legacy or are you still using the vanilla engine?

[diabolik]

OK I'll be back the 2nd of August

Yes I use Legacy sometimes, cause I have so many installations of ET on my computer

Happy holydays and be careful hot weather sun everywhere (not only inside PC lol)

Bye everybody

Hi diabolik, the 0.42.0 release is there and the ssao shader loading bug is fixed.
