How do I check if I have 32 bit drivers installed?

I’m trying to install the app for overwatch and whenever I try to launch it I get the “A required DLL could not be found” and the FAQ says:
If using OpenGL: Make sure you have 32 bit drivers installed (Blizzard App is 32 bit)

If using DXVK, and it works with OpenGL: Make sure you install Vulkan correctly, including 32 bit.

One, how do I know if I’m using OpenGL? I’m just using lutris with the wine-staging. How do I see if I have 32 bit drivers installed? I installed my drivers following this [] guide.

And heres my full settings:
OS: Debian 9.5 stretch
Kernel: x86_64 Linux 4.9.0-8-amd64
Packages: 2441
Shell: bash 4.4.12
Resolution: 1920x1080
WM: OpenBox
WM Theme: Artwiz-boxed
GTK Theme: Adwaita-dark [GTK2]
Icon Theme: nuoveXT2

GPU: Gallium 0.4 on AMD POLARIS10 (DRM 3.8.0 / 4.9.0-8-amd64, LLVM 3.9.1)

Any help would be GREATLY appreciated as Overwatch is probably my number one played game.
