L2 and R2 triggers not functional on PC + Controller

Enabling Steam’s controller input is my current workaround, I had the same issue. I think what it basically does is tricks the game into thinking you are using an Xbox controller, cool thing is the game lets you change the button glyphs so it still makes sense for your PlayStation controller. You can do this by clicking on the game in steam, and going to controller options.

This is still an issue - how do you change the xbox labels to PS labels? Getting confused by the button labels as am new to controller on PC.

For those looking to change the glyphs as the person above mentioned, within PoE2, open the settings (once logged into a character), navigate to the "Input" tab, and scroll down to the "Controller #1" heading.

Under Controller Prompt Art, you are able to change the glyphs to DualSense.
