Two days ago I'm get new hardware with VT-d support and now I'm finally configured it. For a while I was wonder about PA performance difference between Linux and Windows and now I happy to present some results of testing I done in system editor. Tech details: So actual tests was: Celestial view centered on planet (after "close" pressed): Lin: 45-46 FPS Win: 46-47 FPS View on planet (after "edit planet" pressed): Lin: 43-44 FPS Win: 44 FPS Cursor moving fast over 3 top buttons ("preview all", "simulate", "clear system"): Lin: 26-27 FPS Win: 22-24 FPS Cursor moving fast on top of planet surface: Lin: 41-42 FPS Win: 44 FPS View on planet with "simulate" enabled: Lin: 43-44 FPS Win: 44-45 FPS Celestial view (after space bar pressed) with "simulate": Lin: 46-47 FPS Win: 47-48 FPS Obviously gameplay performance might be different, but as far as I see Linux version have performance parity with Windows one on AMD proprietary drivers. I'll do in-game benchmarks after I find way to make those reproducible (at least in limited period of time). Other interesting notice. First time I used Catalyst 13.12 on Windows and it's had worse performance than 14.3 Beta on Linux. So basically Catalyst 14.3 Beta clearly improve OpenGL performance a lot and give +2 +4 FPS improvement in those tests exclude one with cursor over UI.
Does the shadow setting have any effect for you in the system editor? I set shadows to off and it still renders shadows in the editor but not in game during a match.
No idea actually, but I can say for sure both times I tested game after restart so at least AA option was ignored.
Interesting notice. Windows 8.1 + Catalyst 14.3 Beta performance in tests #2;3;4;5 is worse (-4FPS) than in Window 7 and in tests #1;6 (celestial view) it's just a bit worse (-1 FPS) than in Windows 7.
I installed windows 8.1 on my tablet and noticed performance on my whole system and in all my games seemed worse than in win 8.0 So i have reverted to using win 8.0 instead of 8.1
