    RadeonSI is still slower than GpuPro at lower resolutions on counter strike go
    Those 20fps more or less can be the difference between staying always above the 144hertz or having small breaks during gameplay,
    that can hamper the game experience if playing in a more competitive manner.

    The 290 regression is a bug in DRI3 exposed by async page flipping. The fix is actually a mesa patch:

    Note that this patch only helps with sync-to-vblank enabled. Since PTS always sets vblank_mode=0 AFAIK, I'm afraid it can't help for the regressions Michael has reported. If anyone else can reproduce the regressions with PTS (or otherwise with sync-to-vblank disabled), bisecting would still be interesting.

    Nothing matching your description comes to mind offhand, but I guess it's possible.

    Since the CPU seems to stay pegged during the stalls, a system profile taken around one of them might be enlightening, but that might be difficult without a way to reproduce it reliably.

    That makes me sure that more and more of the close source team is contributing to the open source driver and this is also what AMD said will happen.
    yes, because they switched to open kernel, so all blob kernel devs are now working on amdgpu. and i think some other components too

    Great, so hopefully that should take care of the 260X regression as well...

    I was thinking the same regarding Windows comparisons. And add the 290 (hopefully the regression is taken care of soon).

    Well, if you have time and i if am in your place i would first try to find one worse one case... Then start bisect anything, either code but bisecting in game settings first as it might happen only on some setting scenario, etc...

    That way, we might conclude on the end what we actually guessing currently here

    It happens on several maps. Not sure if it's all of them. But the maps in arms race mode are 5v5 maps and the normal mode ones are much bigger, so if that was the case it would be even worse there.

    Better people or you to comment does issue happen if they use other drivers or even different OS... if they have those down to zero fps sometimes, then you should know it is not driver or unsommon issue.

    It can be engine as source is known for stuttering... btw does that happen only on some particular maps or in all? I don't play that really, but often you can find that one map is fine if simple and more large ones made problem.

    I'd like to think that it's rather the game's fault, but wouldn't more people complain about it when it's the second most played game on steam?
