• I've changed the right trackpad to "absolute mouse".
• Changed back buttons to:
  • L4 => ESC
  • R4 => left mouse
  • R5 => right mouse

Changed Steam Deck to 60 Hz and unlimited FPS. Disable V-Sync and limit to 30 FPS ingame. Set graphic settings as low as possible. Enabled dynamic resolution with 30 fps as target.

After logging in for the first time, textures are missing for a few seconds. After this waiting period, the game runs smoothly most of the time. Due to the activated "dynamic resolution", some large artifacts can be seen, especially in end-game content. This depends on how many enemies and/or effects are currently on the screen. For my gameplay, it is better to see artifacts for a short period of time than to not be able to move due to FPS drops. Theoretically, the FPS in "not high endgame content" varies between 60 and 45 FPS. Since I set it to 30 FPS, I achieve those as well. With the exception of the situations mentioned above, there it can also happen that for some time the FPS drop to 20 or even 10 FPS. Under these circumstances, even my PC (RTX 3060 and i5 12400) no longer reaches a smooth 60 FPS.

This is an online game. If there were "problems", this game would be unplayable. On the other hand. If you are experiencing some "fps drops" without those fps drops showing up in the diagnostic overlay, try changing the network mode to "predictive". This option can be found in the in-game settings. This problem has nothing to do with the Steam-Deck, but with a slow network connection.
