With the release of FGLRX 14.10 rc1 I decided to put Unigine Heaven 4 to use and test the proprietary drivers vs the open sauce ones.
I’m also happy to report AMD seems to have fixed that cg shader mip mapping generation issue which was causing Ogre3D games to crash.
FGLRX 14.10: 339 (5.9 – 25.8 FPS)

https://dl.dropboxusercontent.com/u/7464199/mesa.htmlEven though the average FPS are higher, fglrx still has severe frame latency issues which cause the game to look even choppier at times than with the open sauce drivers.
It’s toss up at this point, want a consistent performance at lower FPS? Go Mesa. Want more FPS at a cost of frame time smoothness? FLGRX is your thing.
If you don’t think frame time (consistency) is important, just think of the original Portal on Linux and its constant hiccups. Those were caused by the frame rating being all over the place, ranging from 60-150+ FPS several times per minute.
So apparently Fedora just pushed Mesa 10.1 to the stable repo, that means Metro: Last Light running on the open sauce drivers!
“Even though the average FPS are higher, fglrx still has severe frame latency issues which cause the game to look even choppier at times than with the open sauce drivers.”
how can you tell when its the driver and when its the application? latency can be cause by many things! ssd/hdd speeds, drivers, background apps, game engine etc…monstercam007 wrote:how can you tell when its the driver and when its the application? latency can be cause by many things! ssd/hdd speeds, drivers, background apps, game engine etc…When the only thing that changes is the driver, it’s easy to pin point the fault. The frame latency issues are glaring with FGLRX, while with the open sauce drivers you get a much smoother experience. Even if the average FPS is lower with the latter.
