One minor note: to enable the benchmarking capability, bring up the Beryl Settings Manager, go to the Extras tab at the top, and enable the Benchmark plugin on the left side. Exit the Beryl Settings Manager. You then display the benchmark widget on the desktop with the key combination defined in the Beryl Settings Manager
As you can see above, my combination of hardware and software give a reading of 75 frames/second. I found this rate to be consistent, regardless of what applications I started or what activities I performed on the desktop (such as moving a window, or starting an application such as Google Earth).
My system setup is:
- Athlon XP 2500+, Barton core running at 1.8 GHz on an nVidia nForce 2 motherboard
- A Gigabyte 7600 GS AGP video card with 256MB of GDDR2 memory (which I wrote about installing here)
- 512 MiB of DRAM
- nVidia drivers
- Ubuntu 7.04
- Performance on older ATI-based hardware is horrible. The Gigabyte card replaced a 9600 SE video card (64-bit, 128MiB) in order to be able to run Beryl and Compiz at any decent rate above a snail's pace. And my other machine, europa, running a 9700 Pro, works just fine with the ATI drivers as long as I don't attempt to bring Beryl up.
- Performance on nVidia-based cards is the way you want to go. After installing the Gigabyte card the performance of the Beryl desktop has been silky smooth without artifacts or performance degradation. Again, I'm using the nVidia drivers, not the open source drivers.
