A Mesa Fix Lands To Take Care Of The R9 290 Issue, Intel/Radeon Performance Problems

[M@GOid]

Padoka updated his PPA just before the patch was released... Lets hope he update it again soon.

That really doesn't mean anything. [...] It's not capable of showing performance differences. Please benchmark a game, that would actually tell any real difference.

It actually is a benchmark for this problem (but only this!), because what you want to test is how fast can the driver swap the buffers. So lower gpu load -> better swapping test

I guess with the patch glxgears is not anymore CPU bound

I don't see how you could possibly tell any difference when just moving the window can change fps by hundreds or even thousands. How can you know the difference is from this patch or from a difference in window position.....

That's why quoting out of context is so stupid. I already said this and now I'm forced to repeat myself because you chose to quote only what matters the least.

glxgears is not cpu bound. It's not anything bound. It just doesn't do very much.

Of course it is CPU bound, with DRI2 it is bound to singlethread so more CPU bound and with DRI3 less - it uses more CPU

[droste]

It may changes by a few hundreds fps but this was an increase of at least 50% in "performance". That's not within the error margin. Especially if you read the bug report where they measured before the first change that broke this, after the change and after the fix. It's pretty clear that it is a benchmark for this and even if you repeat yourself it doesn't become more true. And I'm also not sure how the quote was out of context? Nothing you wrote added new infos to this. You just made same claim with more words but without any new evidence.

[dungeon]

But main diff here is probably cos Michel uses xserver git, where there are glamor improvments... but users usually test something else

[duby229]

50% is well within glxgears margin, 10x is within glxgears margin. Just move the window around and you can see that for yourself. This isn't news.

EDIT: Games..... That's what we need to see benchmarked....
