Summary: wwiionline (Battleground Europe): bad fps drops when playing certain sounds Product: Wine Version: 1.1.8 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: directx-dsound AssignedTo: wine-bugs@winehq.org ReportedBy: rasto@ns.ksp.sk
The game suffers very bad fps drops (from ~60 to 0.5-0.2 for few seconds) when certain sounds are played with hardware sound selected. This occurs in all wine sound configurations.
Soundcards tested: 1) Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) 2) E-mu 0202 USB
To reproduce: Install wwiionline (download from ftp://downloads.wwiionline.com/). Run WW2_sse2.exe (or any other executable) to go to offline training. Select a two-engined bomber/transport aircraft, for instance the C47. Start engines with "e". Wait a few seconds until the aircraft starts to roll slowly. Now turn the engines off with "e" again. The problem is most pronounced when turning the engines off like this, but appears (often to lesser extent) often, making the game unplayable with sound. Seems to be present with sound both "hardware" and "software" but not with sound "disabled".
Occurs in all wine versions tested, from 1.1.3 to 1.1.8. OS is Debian, wine built from sources.
