Proponuję kupić notebooka z kartą Nvidia, który nie wspiera technlogi Optimusa.
Producenci gier oraz programów dla Linuksa większa uwagę zwracają na poprawnę działanie aplikacji ze strownikami Nvidia. AMD ma poważny problem w przypadku tworzenia sterowników dla Linuksa z uwagi ignorowanie tej grupy użytkowników. W efekcie Nvidia
uzyskała pewną przewagę:
"Some of the particularly interesting answers include how the managerial view of Linux at NVIDIA has changed over the years, how greater than 90% of the driver's source code is shared between Windows and UNIX platforms, the actual percentage of the Linux driver downloads from the NVIDIA"
"I'd estimate greater than 90% of the Linux driver is cross-platform code. The NVIDIA GPU software development team has made a very conscious effort to architect our driver code base to be cross-platform (for the relevant components). We try to abstract anything that needs to be operating system specific into thin interface layers.
Some examples:
The NVIDIA kernel module is nearly all cross-platform code; the majority of the same code for this component runs on Windows XP, Windows Vista, Windows Win7, MacOSX, Solaris, FreeBSD, and Linux. In fact, the exact same nv-kernel.o binary file can be used on all three of Solaris, FreeBSD, and Linux. The only bits that are Linux-specific are provided as source code in the kernel interface layer of the NVIDIA kernel module.
The NVIDIA OpenGL driver is mostly cross-platform; the only bits that are not cross-platform are abstracted into the window system layer (e.g., GLX, WGL).
The NVIDIA X driver is more UNIX-specific. It shares some code with the NVIDIA display drivers for other operating systems, but due to differences in window systems, it doesn't make sense to share a lot more code here.
The VDPAU driver leverages a lot of the low-level video decoding algorithms from the Windows video driver.
We couldn't provide the Linux product that we do if we didn't leverage so much common cross-platform driver code."
