Bug #: 33795
           Summary: Applications crash when using more than ~500 Mo video
                    memory
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

    Classification: Unclassified

Hello,

I'm experiencing a weird bug since I replaced my old graphic card with a
newer one (nVidia GTX 660). I play a lot of game through Wine (SCII, Guild Wars
2, League of Legends, Skyrim), but some of those(Skyrm and SCII) often crash
with ugly GL errors, GL_OUT_OF_MEMORY among them.

This crash happens when more than ~500-600 Mo of video memory is used
(although my card have 2Gb memory). I tried to limit the memory to 512 Mo
through the appropriate registry key, but it still crashes. If I reduce the
graphics quality, it runs ok, but then, less than 500 Mo video memory is used.
  Moreover, when I play the other games (Guild Wars 2, League of Legends), no
crash appear; but less than 500 Mo video memory is used too.

I don't think the drivers (nVidia proprietary drivers, 319.23) are in cause,
because I easily use 700-800 Mo video memory with Unigine Valley (native)
without any crash.

That's why I think this bug _could_ come from Wine (d3d->opengl part?).

Cordially.

P.S. : I'm running on Arch Linux (i386) with kernel 3.9.4 (PAE enabled), KDE
4.10.
