The difference in speed is considerable, especially for newer graphics cards. Unfortunately, only a few Nvidia GPUs can use this with nouveau installed, none of them very new. This allows the GPU to work harder, and thus perform faster (at the cost of more power). Proprietary Nvidia drivers are far faster than nouveau, especially with newer graphics cards.Īnother drawback is that nouveau lacks something that the proprietary driver has: reclocking. This has its drawbacks, mainly on the speed and compatibility fronts. Basically, developers look at the results of a program and work backwards from there. It's similar to how the Wine project recreates a Windows environment to run programs like Microsoft Office on Linux. Much of the work done by nouveau is through reverse engineering the proprietary Nvidia driver. Nouveau, the open source driver for Nvidia cards, delivers overall poorer results than its proprietary counterpart. While there are open source and proprietary Nvidia drivers for Linux, the best performance comes from proprietary drivers. Should You Use Nvidia Graphics Cards for Linux?
