Originally posted by darkbasic View PostI know I know, nouveau sucks when comes to stability. I am curious about the motivations, maybe nvidia gpus are easier to program?
Also, a while ago Michael showed that enabling PCIE-2 support gave quite a boost to the radeon cards. I'm guessing nouveau drivers have that enabled.Last edited by smitty3268; 30 January 2012, 03:41 PM.

And as far as why slower cards tend to do better on mesa (comparatively)
I'm pretty sure it's because they are less CPU limited. (or PCIE bus bandwidth or latency limited, which amounts to the same thing)
The binary drivers have gone to great lengths to make sure the GPU is never stalling out waiting on the CPU for instructions or data. The mesa drivers aren't as good at that, but for slower cards often the CPU can keep up reasonably well. With the faster cards it becomes really obvious that some of those optimizations are missing.

Originally posted by mirza View PostIt seems that, by the end of this year, Nouveau can catch-up with binary blob performance-wise, making binary blob obsolete in the same second (except for newest chip). Maby that could be a moment for NVIDIA, to get their heads out of their asses and start investing in Nouveau.
With the nouveau driver coming quite close to being on a par with the closed blob, nVidia should embrace this so at least people can continue to use their older cards that are no longer supported by their blob or even provide an alternative.
