Symptoms

Generally low performance, though seemingly close to ready for whitelisting.

Game is stuttering (seems like a frametiming issue) almost constantly, with frequent hitches (though these are probably caused by shaders still being cached).

On medium settings at 1440p the performance on a GTX1080ti and i9 9900k is lower than seems reasonable (hovering around 50-55FPS), considering the recommended specs are a GTX 1060 and an i5.

Possibly also experiencing some artifacting in regards to reflections and transparency appearing low res/grainy, but this has not been compared visually to native. The severity of this seemingly comes and goes, and I haven't found a reliable way to reproduce it yet. See screenshots. The silver/white particles on jacket, hair, edges or reflective surfaces of various objects, and entire floor in background of second image.

Also, the game really doesn't like being alt-tabbed.

The report provides the Proton log at steam-870780.log and system details for Proton 5.0-9, Linux kernel 5.4.0-7642-generic, and an Nvidia GTX 1080ti. Start by reviewing the log and reproducing the report with the game's Click play steps; investigate stuttering, rendering artifacts, and alt-tab behavior. Done would require a reproducible cause and verified improvement, but no source file or test is named.
