With proprietary drivers. Unless you mean Intel, which is only able to run old games (L4D is an old game.)Valve has shown that gaming on Linux works, showing better performance in their opengl tests compared to Windows.
High performance gaming on Windows means you can get 60FPS with high resolutions and maximum details on a demanding game released this year.
Benchmarks say otherwise.You are obviously the one living in a fantasy world.
I don't buy any of your arguments. With that logic, the kernel should not provide any GPL exceptions at all, so that you wouldn't be able to run GPL incompatible software on it. That way, userspace software vendors would open source their products. Yeah, I can see *that* one working.What? The kernel devs have had the exact same position long before Intel and AMD even started dabbling in GPGPU solutions, the reason Linux enjoys such a strong hardware support out-of-the-box is a direct result of their hardnose stance.
No. The kernel is a required, low level component of the OS. Just like the GPL itself provides a built-in exception for using low-level proprietary OS components with GPL software without resulting in a GPL violation, so should the kernel do the reverse. The NVidia driver is a driver, and thus cannot work reliably outside kernel space. Forbidding them from using kernel interfaces is immoral. Why is it OK that I can run a GPL app on Windows, which links against Microsoft's C library, but I can't have a proprietary driver making use of an interface of a GPL kernel?
In my eyes, what the kernel devs are doing is plain bigotry. The kernel is a required component and you cannot work around it. If you're not allowing proprietary vendors to use it in order to be able to offer support and stay competitive in the licensing policy of their choice, then you're being a bigot. If NVidia isn't allowed to interface with the kernel, then Google shouldn't be allowed either. Much of the Android stack is proprietary, yet no one sees a problem with the Linux kernel sitting at the center of it. And NVidia isn't actually even modifying the kernel, let alone distribute it. It's not like they have changed the kernel and refuse to GPL their changesets. The only thing they're trying to do is to use an interface.
