The game fails to start by default. In order to make it run on Fedora, I had to install gperftools, which provides tcmalloc, and symlink the installed ones replacing the game provided files. Steps are:

dnf install gperftools
cd ~/.local/share/Steam/steamapps/common/Counter-Strike\ Global\ Offensive/bin/linux64 


mv libtcmalloc_minimal.so.0 libtcmalloc_minimal.so.0.bak
mv libtcmalloc_minimal.so.4 libtcmalloc_minimal.so.4.bak
ln -s /usr/lib64/libtcmalloc_minimal.so.4 libtcmalloc_minimal.so.0
ln -s /usr/lib64/libtcmalloc_minimal.so.4 libtcmalloc_minimal.so.4

then, one can start the game with one of the following options:

For OpenGL:
    gamemoderun %command% -novid -nojoy

For Vulkan:
    gamemoderun %command% -novid -nojoy -vulkan
