Bug ID: 49845
           Summary: Sacred Gold: very bad performance (low fps) when
                    zoomed out
           Product: Wine
           Version: 5.0.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Sacred 1 Gold provides 3 zoom levels: Very close, middle and zoomed out. I
guess most people really only use the zoomed out setting, the other two show
such a small portion of the world that i don't know how anybody could enjoy the
experience.
Unfortunately the zoomed out setting gives very bad performance, around 20fps
on a Ryzen 2700X @ 3.7GHz. Using the middle zoom setting fps go up to about
30-35fps and the very close zoom setting gives 55-60fps.

I don't really understand what's going on, I think this is a very old game and
a 8-core 3.7GHz CPU should have no problem whatsoever to run it. The 20fps i'm
getting make the game really unenjoyable to the extent where i would rather
boot windows to play it (where i'm getting 60fps at all zoom levels).

I tried with and without CSMT, fixing the process to a single CPU core etc.
Unfortunately no luck. It is really strange that the game would run at almost
60fps when zoomed in and then take such a massive performance hit when zooming
out.
