Bug#1010850: supertuxkart: bad performance compared to standalone binary release

[Julian Groß]

Package: supertuxkart
Version: 1.3+dfsg1-3
Severity: normal

Dear Maintainer,

the SuperTuxKart package runs with substantially worse performance than the standalone binaries from supertuxkart.net
Depending on the situation, my framerate increases by 40-80 FPS when switching to the standalone binaries.
According to a dev, they don't do anything special with their builds. They only have compiler optimization enabled. ("g++ -Ofast")
To me it feels like compiler optimization might just be off for the Debian package.
As far as I am aware, both releases are built from the same source version and both use the same configuration (graphics settings, etc.) at runtime.

Greetings
Julian Groß
