Summary: Portal lags for a second when creating first portal Product: Wine Version: 1.2-rc2 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: matejcik@gmail.com
when playing Portal, first time i open a portal the game stutters and lags for about a second. The lag appears when the portal just hits the ground and is about to open. It blocks the "portal opening" sample, which loops a couple times before the game resumes. It seems to be somewhat worse when GLaDOS is speaking at the same time, but that might just be a false perception (because GLaDOS's voice stutters as well). It happens with computer-controlled portal guns too, e.g. at the very start of the game, where a portal is automatically opened for you in the starting chamber.
Creating subsequent portals in the same area is OK, but sometimes I experience the same stutter in the same map a few rooms further. It reproducibly happens when a new map is loaded.
It happens with any dxlevel setting from 80 through 98. Portal depth is set to 2, i didn't test with lower setting, i will try with 0 and report back.
i checked in Windows and creating the first portal is OK
my system is intel core i5 with 32bit Ubuntu 10.04 and Wine from PPA. GPU is Radeon HD 4670, binary fglrx driver i am playing with compiz turned off
