Compatibility Report

  • Name of the game with compatibility issues:Arcana Heart 3 LOVEMAX SIXSTARS!!!!!! XTEND
  • Steam AppID of the game: 661990

System Information

  • 1 TB OLED Steam Deck LE
  • Proton version: Experimental

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

Game seems to run too fast on my oled deck normally (runs at 90 on oled when it should be running at 60), the game runs normally if i cap the framerate to 60 using the decks frame limiter or if I set DXVK_FRAME_RATE=60 as a launch command.

This problem also occurs on the crowd funding edition of XTEND and the older LOVEMAX version (370460)

Reproduction

Run the game on oled or any device with a refresh rate higher than 60 fps

Sspiffeeroo 2024-12-30 github

AH3LMSSX (661990) runs at capped 60 fps for my desktop Linux PC with 240 Hz monitor. FPS Control is turned off in the game settings.

The older AH3LM (370460) runs at uncapped frame rate (game speed is too fast).

@spiffeeroo

You mean AHLMSSX runs capped without any settings? I never touched or toggled anything on my copy, fresh install, pulled up Mangohud and can confirm the game ran at 90 FPS on my OLED Deck, not 60 fps. there's also another protondb report that also states the xtend version runs too fast on monitors higher than 60 unless you cap it with "DXVK_FRAME_RATE=60 %command%"

Edit: Took a screenshot to show it runs at my oled decks default refresh rate unless I cap it

Edit 2: Turns out it only runs at 60 without any tweaks if it's set to full screen, if it's running in windowed mode, it runs at the monitors default refresh rate

I updated the PR to include the Xtend version.
