            Bug ID: 35776
           Summary: Crysis is extremely slow in Wine 1.7.14
           Product: Wine
           Version: 1.7.14
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs at winehq.org

Wine 1.7.14 brings an extreme slowdown in Crysis and I found that
this is caused by two regressions.

1) With Crysis under plain Wine 1.7.14 I see constant flickering
and the game shows less than 1 FPS. This is a regression
introduced by the commit

wined3d: Restore the pixel format of the window whose pixel format
was actually changed.

A similar problem is considered in Bug#35767 and patches suggested
there do not help as well as for that bug. This commit also affects
some old games (TES3:Morrowind, TES4:Oblivion) but slightly: it gives
about 5 FPS less than in Wine 1.7.13.

2) But after reverting the above commit I see nevertheless that Crysis
shows significantly less FPS than with Wine 1.7.13 (average 30 FPS
with 1.7.14 versus 45 FPS with 1.7.13). The second problem is caused by

wined3d: Filter redundant WINED3D_MAP_DISCARD buffer maps.

After reverting both commits in Wine 1.7.14 I see the same framerates
as in 1.7.13 in all games.

It is interesting that Wine with Command Stream patches by Stefan Doesinger
encounters only the first problem but the second commit does not cause
slowdowns.
