AMD Kabini HD 8210: RadeonSI Gallium3D Can Outperform Catalyst

I can't say these test results are very surprising. The IGP in this is probably slow enough that the RAM can actually keep up with it (it seems the open source drivers have a greater issue with memory bandwidth). I'm SURE if Michael did another test involving different RAM frequencies with the HD8210, the results won't be as drastic as they were with the A10. Another possible cause of the better performance is the open source drivers are incredibly tiny and simple compared to catalyst. Catalysts' bloat and complexity probably is a little too much for that puny piece of hardware to handle. But, just because its puny, it doesn't mean its bad.

In my personal experience with Mesa, glitches are everywhere in most games and especially on Steam proprietary games.
For example in my HTPC with RV630, Wargame European Escalation is unplayable due to heavy glitches and flickering.

Probably another HyperZ issue, there have been a few of them for the r600g series of GPUs.
Try add this to the Steam launch options and see if it fixes it:
R600_DEBUG=nohyperz %command%
Also, are you using oibafs repo?

Anyway, DRI3 should vastly improve those scores, for those who care.Michael Larabel

Talking about Catalyst stutter in Linux reminds me something interesting...
I tested also Catalyst in Windows XP 32bit, Windows 7 32bit, Windows 7 64bit, Windows 8 64bit and Windows 8.1 64bit with OpenGL games like ET:QW and found out some things interesting...
Starting with the lest important...
The maximum performance as in max frame rate was with XP, Win7 was way worse, Win8 a bit worse than Win7 and Win8.1 was a bit worse than Win8.
As for stuttering, in XP there is NO stuttering at ALL....but besides XP, all other Windows versions tested stutter like crazy even is not that noticeable in the variation of FPS with the switch to show FPS, it's VERY clear in the image as we move around even when straffing...it's simply IMPOSSIBLE to play it with the rig used in test.
...and yes, in Linux stutters even with Linux 32bit...so i guess there is code shared between Catalyst for Linux and Catalyst for Win7 and above but there is something different in Catalyst for XP....or is there something wrong with Win7 and above with OpenGL ? but if it was this last option that wouldn't explain the Linux problem.Last edited by AJSB; 22 February 2014, 01:38 PM.
