My old Laptop from 2011 is an Ac= er Aspire 5250 with an old GPU AMD Radeon HD 6250, and a C-50 processor. Using radeon firmware on Linux. I uninstalled Linux, since it will never be equal or better Windows 10 Lite= in this case. I do not pretend to reinstall linux on it, since it cannot even = play a YouTube video or play SuperTuxKart without lagging. Different from Windows with Catalyst Radeon drivers which works fines, for both cases. Seems like original radeon firmware from AMD was not open source neither well document= ed back in the time, so I think it is literally impossible a equal or better driver for Linux. --=20 You may reply to this email to add a comment.
