And as you've written, it isn't only about performance.<BR/><BR/>>> Also there's the generic pixmap cache which is already being used in quite a few games to speed up rendering of game elements and background from SVGs.<BR/><BR/>Sorry for stupid question, but how does this work? I guess the games might start faster, but if you resize the window, there will still be a "lag"? (notice quotation marks. I hope you understand what I mean).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6144115306124694421.post-44208930102544589722007-09-02T23:18:00.000+03:002007-09-02T23:18:00.000+03:00Cool thing.

All the libraries etc have to be reloaded as well.<BR/>Also the 11 seconds is until the time Dolphin's UI has stopped loading icons.
