When generating normal map mipmaps, I use a Kaiser filter and renormalize the values at each pixel of each mip level. I'm also using BC5 compression. While the results are better than standard...

Thanks for the post. So, NVidia is encountering some headwinds...

I had no idea. Thanks for letting me know what "people at companies" do with their time.

Yeah, I read it. It's horribly inaccurate as I mentioned in my other responses in this thread. Go read Aaron's original emails. Nvidia has NOT said that Optimus will be officially supported. ...

Nvidia should have put a big disclaimer on the linux driver download page indicating that mobile cards are unsupported. Instead they pretend they are supported and have some fine print on the...

Alfonse, don't be a troll. I took issue with "one class of hardware on one class of machine". It's not. It's basically ALL linux laptops. Can you point me to the source of your statistics? I...

LOL. Do you have NVidia stock? It's not "one class of hardware on one class of machine". It's pretty much all laptops with recent Nvidia GPUs in them. Maybe if you researched it a little more,...

Ummm. No, I don't think that's an overreaction. The fact is that there is no satisfactory working solution and this point in time. Linus was justified in his response to Nvidia. That article was...

My company just ordered a laptop with a 640 M in it. Unfortunately, the linux driver doesn't detect the card. We found this webpage: http://techies.ncsu.edu/wiki/bumblebee-nvidia

The page states...

Suppose a shader uses multiple texture arrays and needs different slices from all of them. What's the best way to hand the slice info to the shader? Do you just use multiple texture coordinates?
...

We're having problems with the newer Nvidia drivers when both bindless and vertex attribute instancing via glVertexAttribDivisor are enabled. Are there any known issues with using both at the same...

No, I've never seen a completely white fire.

This poster had the same problem. http://gamedev.stackexchange.com/questio...g-and-particles

I'm trying to use additive blending on a bunch of fire particles. The fire particles are using a texture with no alpha. It works really well when the background is black. However, when the...

I'm surprised I didn't find anything in this forum on Direct State Access. Everyone seems to want DSA included in the core, and I haven't heard a good reason that it's not included.

At the very...

This isn't OpenGL related, but I've been having problems with my Radeon 5800.

Sometimes if I shutdown my computer and restart, the monitor remains blank. I have to leave the computer off for a...

No, my card doesn't support ARB_texture_rg, so it's not surprising that GL_R32F didn't work. I'm looking for any floating point format that will work. I haven't had any success.

The card...

Unfortunately, I need to modify my application so it will run on an old GeForce 7900. My application sets up a 32 bit floating point FBO by calling glRenderbufferStorageMultisample with GL_R32F.
...

How are you uploading the index list?

Rather than sending entire matrices, you might be able to send only orientation and position and save some bandwidth to the card. I've found that instancing...

I have a 480 with 260.19.12 drivers installed on 64 bit OpenSUSE. I have two monitors and I'm running my application in windowed mode. I noticed there is one window position that causes my...

Seems like you contradicted yourself...

You're correct. From the spec:

"Matched block names within an interface (as defined above) must match in terms of having the same
number of declarations with the same sequence of types and the...

I'm been experimenting with interface blocks and I'm trying to determine if the following is valid GLSL because it doesn't work on a NVidia Geforce 480 with 256.53 drivers. If I change both "varOUT"...

Thanks Foobar. That's a helpful link. I know that Mark Kilgard has been critcial of deprecating features.

Is there a performance advantage from using a core OGL profile, i.e. setting WGL_CONTEXT_CORE_PROFILE_BIT_ARB?
