Seem like they support a later OpenGL version and more OpenGL features at least:

"Nouveau's NVC0 Gallium3D driver for GeForce GTX 400 "Fermi" GPUs and newer has all of OpenGL 4.0 and is even advertising OpenGL 4.1 compliance as shown by the screenshots I took with a GeForce GTX TITAN on Mesa Git this morning. The Intel i965 DRI driver just has a few extensions to enable for OpenGL 4.0 support as does the AMD Radeon R600/RadeonSI Gallium3D drivers. The Softpipe and LLVMpipe software rasterizers are much further behind and will probably be a number of months before these drivers handle OpenGL 4.0."

As far as performance goes the support for Maxwell (the latest GPU generation) seem to be shit, older ones seem to be doing quite well with 15-70% or so of the performance of the close drivers:

For more recent AMD cards the open-source driver is even worse relative their catalyst driver than Noveau was vs Nvidias and I guess their catalyst driver isn't as good as the Nvidia one either so go figure:

Xonotic 0.8 1080p High:
GTX 680 Nvidia driver: 269 FPS
GTX 680 Noveau: 105 FPS.
R9 285 Catalyst: 207 FPS
R9 285 Mesa: 44 FPS
GTX 750Ti Nvidia driver: 201 FPS
GTX 750Ti Noveau: 19 FPS.

So in that one I'd say the GTX 750Ti + Noveau is doing even worse than the R9 285 + Mesa one.

R9 285 with Catalyst seem to be doing quite well there.

But step back one generation and the Kepler GTX 680 owns them all.

I've drank 1500 bq / liter water for 15? years time.

I doubt a few greens during some days would make much of a difference.

Maybe you upgraded to 64 bit?
Use 32 bit Chrome instead?

Then again now with the version I have (likely 43) Chrome crashes in Windows without Windows ever saying it's running out of RAM.

But it did kill off terrorism!

Also it's much easier to find and meet earthlings.

Rocket packs.

(Also who used up all the oxygen of their time?)

Why do they suck and if they sucked shouldn't there be clear competitors which sucked less?

How good is Yahoo? At least they too offer a massive mail. And lots of picture space too.

I think this is a great idea, but we really need to make to lay the foundation for the next generation of computer controlled vehicles.

Do I know what that is? Nope, but I think it would be reasonable for computer systems on my car to be informed immediately if there is a problem ahead, whether it be damage to road detected by sensors in the plastic road itself or simply congestion to inform my vehicle to take an alternate route.

Perhap road sensors could detect the provide feedback to rooba-plows as well and make noises to scare deer off of country roads well in advance of cars :)

To sell to the Beatles? (Or any other Music loving Brits.)

Why complicate things?

1. Make cockpit.
2. There's no "..." - Put a "European" Muslim behind the controllers and promise him 72 virgins, fame and purpose.
3. Profit.

The Japanese figured it out too. Us Scandinavians as-well.
Simple.

I'm a conservative male Indian ally. I definitely support equal rights for everyone and have very dear friends for whom marriage equality politics is quite personal.

Well.. I'm not socially conservative, and I'm not fiscally conservative either. Ok so I'm not really "conservative" at all, but my point is stereotyping is wrong.

I've never been to Seattle, but I love the pacific NW, and it seems like you have access to both city and nature in that area. It's too bad Amazon is not a great place to work. They seem much more Linux-friendly than the other big tech employer in the area (Microsoft)

There may be a difference in how much we use our computers (Mine was the 2.13 GHz Core 2 Duo with 8600m GT one.)

Yeah. Microsoft contribute $25,000-$50,000 towards a project whose product it uses.

Surely something must be fishy with that! Considering it's such a huge amount of money for Microsoft and so on (Who just decided to write of 8 billion on their purchase of Nokia mobile phones for instance..)

My Macbook Pro was used for 1.5 year and performed poorly after 1,

What's your point really? Nothing magical about Apple gear. The specs in your Macbook are weak and I know lots of Apple users has complained about how the latest OS is slow on their devices.

It's just trickery to keep the Chinese back.

"Here. Look at our latest fighter plan plans! This is going to be the shit! Why don't you make a bunch of these suckers?"
