That is a valid concern in theory, but in practice, improvements to drivers for old GPUs rarely break things. There are regression tests... and part of it might be Timor being very diligent in his work.
This is my point: you won't see them because the people able to report the breakage are rare to non-existent anymore, because most those who were able to do so did move to recent GPUs. The real "normal" users with old GPUs will be forced to move to newer hardware.
The "tests" are nowhere near the QA which has been done by the real stuff out there. Come on, this is border line hypocrit.
I am sorry, but I have to severely disagree: this has more a taste of planned obsolesence than actually improving old GPU performance.
At least if we could get some amount of c++ to plain and simple C (namely a language with a simple syntax) port, would be great though.
