I've been playing the game for 5 hours and it runs perfectly. No glitches, frame stuttering, or weird artifacts. Just make sure that when you first load the game and the screen is black, click a few times with your mouse to get it to start. I'm not sure if this is a quirk unique to Proton or if this also happens on Windows.
To run the GOG version on Lutris, I used Winetricks to install amstream, quartz, and Visual C++. The will especially not run properly if Visual C++ isn't installed. Be sure to run on D9VK as the game uses DirectX 9. After that, it runs flawlessly outside of skipping past the opening and ending movie.
After using the "PROTON_NO_ESYNC=1 PULSE_LATENCY_MSEC=30 %command%", the game runs very well. No graphics or audio issues. There weren't many framerate drops from what I experienced. I'm not sure how much of a performance hit there is going from Windows to Proton, but I'm personally satisfied with the performance.
With the latest Proton update, I tried the game out with D9VK enabled. You still have to disable esync or otherwise, the sound won't work properly. To enable D9VK and disable esync, enter "PROTON_NO_ESYNC=1 PULSE_LATENCY_MSEC=30 PROTON_USE_D9VK=1 %command%" (without the quotations) under "Set launch options". I notice some framerate improvements as I play the game. There are still some areas where the framerate is lower than acceptable such as Jann's Challenge. However, D9VK was just included with Proton for the very first time, so it should get better down the line.
The game works out of the box and detects my DS4 without a problem. Performance is good at ultra settings and 2x SSAA. What prevents me from giving the game a platinum ranking are the occasional freezes I get while playing. However, these freezes are uncommon and you can easily avoid them by playing with breaks in between.
I played the GOG version of the game through Proton 4.2. It works perfectly. DualShock 4 support is out-of-the-box. All you have to do is hook it up by USB or Bluetooth and nothing else.
