There is no native version of this game. The 'Linux native beta' available through steam is just a prepackaged WINE configuration with outdated dependencies. It works on my system, but you're better off using Proton directly anyway.
Under Proton 6.3-8, it works out of the box on my system. The resolution is limited to 640x480, but dgVoodoo2 also works fine as a wrapper (you need to put ddraw.dll in the main directory of the game and use winecfg to set ddraw to native). Visuals can be improved in dgVoodoo2 by using phong shading and multisampling. I then use FSR upscaling through gamescope to scale everything up to 4K. You could also use dgVoodoo2 to force a higher resolution directly, but the backround art in the game is locked at 640x480 and becomes blurry when bilinearly stretched. I find it much better to just keep everything at 640x480, use multisampling, and then upscale everything through FSR.
Otherwise, everything works well enough. I'm pretty sure there's a memory leak, and fire effects slow the whole thing down -- but these problems exist in the Windows version, and in my testing running through Proton hasn't ever crashed, whereras the game did crash repeatedly in Windows.
Nethergate requires a virtual desktop set to 800x600 and will crash if you attempt to force it to fullscreen. In my testing it does run fine when forced to a fullscreen borderless window through gamescope.
Nethergate requires gdiplus_winxp, renderer=GDI, vd=800x600, and the OS must be set to Windows XP.
The game is indeed unusable out of the box in any version of Proton -- either the mouse doesn't work, there's massive flickering, it crashes, or it only displays in a tiny corner of the screen. Using these settings (winetricks gdiplus_xp renderer=gdi vd=800x600 winxp) is a near native experience with only an occasional screen flicker.
