http://bugs.winehq.org/show_bug.cgi?id=31071 Bug #: 31071 Summary: DotA 2: overbright/broken lighting effects Product: Wine Version: 1.5.7 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: cephryx(a)gmx.net Classification: Unclassified (This is a lengthy one because there are already lots of observations and attempt-fixes to describe.) DotA 2 is suffering from weird overbright lighting effects issues, best seen on these screenshots: appdb.winehq.org/appimage.php?iId=39263 appdb.winehq.org/appimage.php?iId=39265 All heroes, items and buildings having some lighting effects are affected. Static map decoration (flares, ...) is not (or at least to a very minor extent). Steps to reproduce: - start the game client and create a lobby in all-pick mode - start the match and pick Lina - have a look at what's supposed to be the hero's flaming hands, or at the visuals of her second spell See the attachend image for a direct comparison (what it SHOULD vs. what it DOES look like). My personal observations regarding the problem: - does not seem to occur with other source engine games (HL2, Portal2, L4D2) - persists throughout: -- ubuntu 11.04, 11.10, 12.04 -- the propriatary nvidia graphics driver series 295.xx to 302.17 (and most likely also before) -- wine 1.3.x, 1.4.x and 1.5.x up to 1.5.7 -- 32bit and 64bit systems -- kernel versions 2.6.x to 3.2.0-26-generic -- various window managers (2D as well as 3D-enabled ones) - the only wine registry setting having an effect on the problem seems to be "OffscreenRenderingMode = backbuffer" -- setting it, the overbright effect is gone, but pretty much anything else gets messed up (ambient lighting is too low and somewhat greenish; continuity of visual effects is broken, etc) - no imgame setting / console variable seems to have an effect - none of the options in the 'nvidia-settings' tool has an effect - creating a fresh 32bit wine prefix with 'WINEARCH=32bit' (instead of defaulting to 64bit) has no effect - confirmed to happen on Geforce GTX 8800, GTX 260, GT 330M Note: Unlike other source games, DotA 2 must be run with the '-nod3d9ex' parameter. Otherwise it won't render at all. However, doing so does not cause the described visual issues on Windows. I am currently using: - wine-1.5.7, GeForce GTX 260, nvidia driver 302.17, Xubuntu 12.04 x64 (xfwm4.10.0), kernel 3.2.0-26-generic I am suffering from this bug http://bugs.winehq.org/show_bug.cgi?id=30270 which MIGHT be related to the problem (though I have no evidence to prove this assumption right or wrong). The three provided logs were created with WINEPREFIX=~/.wine/dota2 wine Steam.exe &> dota2.txt and split around: - steam being fully loaded - dota 2 being fully loaded - creating a lobby, starting the match, picking a hero and entering the game map (gonna add the logs to messages below this one because I cannot create several attachments...) Though it only seems like a cosmetic problem, this bug results in a SEVERE impact on gameplay, since the player loses track of what's happening when only seeing huge overbright explosions. Also note the discussion taking place on the game's AppDB site (http://appdb.winehq.org/objectManager.php?sClass=version&iId=24458), under the message "Weird lighting effects bugs/issues", for some more details. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
