Actually, this wouldn't even be a huge job, maybe 8 hours or so. Anyone wanna hire me?

They've been doing some interesting stuff over at pcper lately
Frame Rating: A New Graphics Performance Metric If the new year will bring us anything, it looks like it might be the end of using "FPS" as the
I'd think that should work well with linux too since it's a dedicated external system capturing the output
I notice stuttering in unigine tropics benchmark personally, I wonder if that's fglrx or just the benchmark itself.

I have middle graphic card, quad core cpu, 8GB of memory, ssd for the OS. Then correct computer. All is fast in console only. More difficult: Dual screen, multiple virtual desktop.
In the case of 7000+ serie, the amd drivers have a problem.
I things a benchmark of all linux factor will help the dev to see and solve the problem (drivers, scheduler, X/Wayland?, ...). But no on FPS, on max latency.

Phoronix should include in their test the latency check for graphic card
Do we have a volunteer?

When running furmark in wine I also get massive slowdowns in X. http://www.ozone3d.net/benchmarks/fur/
But it usually doesn't happen for normal games, only at extreme gpu stress.

Compositing should have very little impact but in practice it seems that it doesn't work so well and there are big slowdowns.

And related to the FPS. Just yesterday I have tried a bit skyrim in windows 7 on a middle class notebook with the newest stable catalyst from amd.com. It definitely has problems with latency. Sometimes even if fraps displays 40+ FPS I see a very noticeable micro stutter. So it probably depends on multiple factors like the game, the drivers, the scheduler, etc.Last edited by ChrisXY; 04 January 2013, 11:18 AM.

Latency on linux
Hello,
I'm not sure to be into the right forum.
To follow this french article:
The max latency is very important. I have noted under linux: correct FPS but some time a big latency/FPS slow down. Same for my hdd.
Phoronix should include in their test the latency check for graphic card (I have have big slow down when I'm playing and kopete/skype open a window). And for hdd when you you have file copy in progress in graphic (KDE/Gnome?) and you try open an application (like chrome, with multiple small file to open).
