We all use or use the Wine program to launch windows applications. But unfortunately, Wine, unlike its commercial counterparts CrossOver and Cedega, does not have a GUI for managing applications (winecfg is a bit wrong). Q4wine is designed to close this space.
So, what can Q4wine:
')
Of course, run Windows programs through Wine with the replacement of a DLL and some other goodies, for example, running on another X server:


Manage Wine processes (terminate, change priority):

I note that it is necessary when the game “slows down”, sometimes it helps :).
Manage Wine prefixes:

You can import and export prefixes:

For each prefix you can configure:
- Substitution dll-ok from Wine
- Path to executable files and Wine libraries (i.e. several versions of this free WinApi implementation can be used)
Mount iso and nrg
Such an opportunity is in Cedega, it is necessary in order to be able to install the game from the disk image:

Install components using Winetricks
You can install DirectX and other necessary components through Setup -> System Software -> Run Winetricks

PS: Do not scold too much, this is my first topic. It is an overview, step-by-step guide on tuning and installing applications I will write later.
