Summary: Kirikiri based games update screen slowly Product: Wine Version: 1.1.2 Platform: PC URL: http://kikyou.info/dl_redirect.php?%2Ftvp%2Ffiles%2Fkr23 0rc1.lzh OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: drakh@spamcop.net
Games based on the open source Kirikiri engine update the screen rather slowly. These are Japanese visual novels, mainly consisting of static images with some simple filters and compositing, accompanied by text and sounds. They're very undemanding resource wise, and screen updates happen more or less instantaneously in Windows on the same hardware. It's most noticeable when the background image changes, taking a second or two to load from top to bottom, but even text rendering is clearly slower when fast forwarding through a scene.
The engine has been used for commercial games like Fate/Stay night, though the author's generic build (linked to in the URL field) has a simple example script that demonstrates the problem. To run it, you need to have Japanese language support installed, then launch "\kirikiri2\krkr.eXe" (passing wine the LANG=ja_JP.UTF-8 variable) and point it to the "\kag3\syoukai" folder.
