current 2d performance

[Gentooer]

I just played around with some different gtk engines. Switching from Clearlooks to almost any other engine like Crux cuts my total time by about 30 seconds!

5 days later... notice the HUGE improvement... keep it up. :-)

It's a Core 2 Duo @ 2.2GHz. Your GtkComboBox and GtkDrawingArea (Circle, Text) tests performed better but my test results were better overall. I kinda doubt the CPU would make much of a difference. IMO, more likely any differences between our test results are because of a different GPU (as you pointed out), driver, or GTK software issue.

I have similar software installed and my hardware is a 1.66Ghz C2D with a 945GME.

What cpu do you have? I wonder how much of the differences were caused by the GPU and how much impact the CPU had.

The first thing I notice is the excessive times for GtkComboBox, GtkComboBoxEntry, and GtkDrawingArea (Circles, Text).

Textured Video looks beautiful now (no more tearing). Keep up the good work.
